What is a Focus Group | Step-by-Step Guide & Examples

Published on December 10, 2021 by Tegan George . Revised on June 22, 2023.

A focus group is a research method that brings together a small group of people to answer questions in a moderated setting. The group is chosen due to predefined demographic traits, and the questions are designed to shed light on a topic of interest.

What is a focus group, step 1: choose your topic of interest, step 2: define your research scope and hypotheses, step 3: determine your focus group questions, step 4: select a moderator or co-moderator, step 5: recruit your participants, step 6: set up your focus group, step 7: host your focus group, step 8: analyze your data and report your results, advantages and disadvantages of focus groups, other interesting articles, frequently asked questions about focus groups.

Focus groups are a type of qualitative research . Observations of the group’s dynamic, their answers to focus group questions, and even their body language can guide future research on consumer decisions, products and services, or controversial topics.

Focus groups are often used in marketing, library science, social science, and user research disciplines. They can provide more nuanced and natural feedback than individual interviews and are easier to organize than experiments or large-scale surveys .

Focus groups are primarily considered a confirmatory research technique . In other words, their discussion-heavy setting is most useful for confirming or refuting preexisting beliefs. For this reason, they are great for conducting explanatory research , where you explore why something occurs when limited information is available.

A focus group may be a good choice for you if:

• You’re interested in real-time, unfiltered responses on a given topic or in the dynamics of a discussion between participants
• Your questions are rooted in feelings or perceptions , and cannot easily be answered with “yes” or “no”
• You’re confident that a relatively small number of responses will answer your question
• You’re seeking directional information that will help you uncover new questions or future research ideas
• Structured interviews : The questions are predetermined in both topic and order.
• Semi-structured interviews : A few questions are predetermined, but other questions aren’t planned.
• Unstructured interviews : None of the questions are predetermined.

Differences between types of interviews

Make sure to choose the type of interview that suits your research best. This table shows the most important differences between the four types.

Topics favorable to focus groups

As a rule of thumb, research topics related to thoughts, beliefs, and feelings work well in focus groups. If you are seeking direction, explanation, or in-depth dialogue, a focus group could be a good fit.

However, if your questions are dichotomous or if you need to reach a large audience quickly, a survey may be a better option. If your question hinges upon behavior but you are worried about influencing responses, consider an observational study .

• If you want to determine whether the student body would regularly consume vegan food, a survey would be a great way to gauge student preferences.

However, food is much more than just consumption and nourishment and can have emotional, cultural, and other implications on individuals.

• If you’re interested in something less concrete, such as students’ perceptions of vegan food or the interplay between their choices at the dining hall and their feelings of homesickness or loneliness, perhaps a focus group would be best.

Once you have determined that a focus group is the right choice for your topic, you can start thinking about what you expect the group discussion to yield.

Perhaps literature already exists on your subject or a sufficiently similar topic that you can use as a starting point. If the topic isn’t well studied, use your instincts to determine what you think is most worthy of study.

Setting your scope will help you formulate intriguing hypotheses , set clear questions, and recruit the right participants.

• Are you interested in a particular sector of the population, such as vegans or non-vegans?
• Are you interested in including vegetarians in your analysis?
• Perhaps not all students eat at the dining hall. Will your study exclude those who don’t?
• Are you only interested in students who have strong opinions on the subject?

A benefit of focus groups is that your hypotheses can be open-ended. You can be open to a wide variety of opinions, which can lead to unexpected conclusions.

The questions that you ask your focus group are crucially important to your analysis. Take your time formulating them, paying special attention to phrasing. Be careful to avoid leading questions , which can affect your responses.

Overall, your focus group questions should be:

• Open-ended and flexible
• Impossible to answer with “yes” or “no” (questions that start with “why” or “how” are often best)
• Unambiguous, getting straight to the point while still stimulating discussion
• Unbiased and neutral

If you are discussing a controversial topic, be careful that your questions do not cause social desirability bias . Here, your respondents may lie about their true beliefs to mask any socially unacceptable or unpopular opinions. This and other demand characteristics can hurt your analysis and lead to several types of reseach bias in your results, particularly if your participants react in a different way once knowing they’re being observed. These include self-selection bias , the Hawthorne effect , the Pygmalion effect , and recall bias .

• Engagement questions make your participants feel comfortable and at ease: “What is your favorite food at the dining hall?”
• Exploration questions drill down to the focus of your analysis: “What pros and cons of offering vegan options do you see?”
• Exit questions pick up on anything you may have previously missed in your discussion: “Is there anything you’d like to mention about vegan options in the dining hall that we haven’t discussed?”

It is important to have more than one moderator in the room. If you would like to take the lead asking questions, select a co-moderator who can coordinate the technology, take notes, and observe the behavior of the participants.

If your hypotheses have behavioral aspects, consider asking someone else to be lead moderator so that you are free to take a more observational role.

Depending on your topic, there are a few types of moderator roles that you can choose from.

• The most common is the dual-moderator , introduced above.
• Another common option is the dueling-moderator style . Here, you and your co-moderator take opposing sides on an issue to allow participants to see different perspectives and respond accordingly.

Depending on your research topic, there are a few sampling methods you can choose from to help you recruit and select participants.

• Voluntary response sampling , such as posting a flyer on campus and finding participants based on responses
• Convenience sampling of those who are most readily accessible to you, such as fellow students at your university
• Stratified sampling of a particular age, race, ethnicity, gender identity, or other characteristic of interest to you
• Judgment sampling of a specific set of participants that you already know you want to include

Beware of sampling bias and selection bias , which can occur when some members of the population are more likely to be included than others.

Number of participants

In most cases, one focus group will not be sufficient to answer your research question. It is likely that you will need to schedule three to four groups. A good rule of thumb is to stop when you’ve reached a saturation point (i.e., when you aren’t receiving new responses to your questions).

Most focus groups have 6–10 participants. It’s a good idea to over-recruit just in case someone doesn’t show up. As a rule of thumb, you shouldn’t have fewer than 6 or more than 12 participants, in order to get the most reliable results.

Lastly, it’s preferable for your participants not to know you or each other, as this can bias your results.

A focus group is not just a group of people coming together to discuss their opinions. While well-run focus groups have an enjoyable and relaxed atmosphere, they are backed up by rigorous methods to provide robust observations.

Confirm a time and date

Be sure to confirm a time and date with your participants well in advance. Focus groups usually meet for 45–90 minutes, but some can last longer. However, beware of the possibility of wandering attention spans. If you really think your session needs to last longer than 90 minutes, schedule a few breaks.

Confirm whether it will take place in person or online

You will also need to decide whether the group will meet in person or online. If you are hosting it in person, be sure to pick an appropriate location.

• An uncomfortable or awkward location may affect the mood or level of participation of your group members.
• Online sessions are convenient, as participants can join from home, but they can also lessen the connection between participants.

As a general rule, make sure you are in a noise-free environment that minimizes distractions and interruptions to your participants.

Consent and ethical considerations

It’s important to take into account ethical considerations and informed consent when conducting your research. Informed consent means that participants possess all the information they need to decide whether they want to participate in the research before it starts. This includes information about benefits, risks, funding, and institutional approval.

Participants should also sign a release form that states that they are comfortable with being audio- or video-recorded. While verbal consent may be sufficient, it is best to ask participants to sign a form.

A disadvantage of focus groups is that they are too small to provide true anonymity to participants. Make sure that your participants know this prior to participating.

There are a few things you can do to commit to keeping information private. You can secure confidentiality by removing all identifying information from your report or offer to pseudonymize the data later. Data pseudonymization entails replacing any identifying information about participants with pseudonymous or false identifiers.

Preparation prior to participation

If there is something you would like participants to read, study, or prepare beforehand, be sure to let them know well in advance. It’s also a good idea to call them the day before to ensure they will still be participating.

Consider conducting a tech check prior to the arrival of your participants, and note any environmental or external factors that could affect the mood of the group that day. Be sure that you are organized and ready, as a stressful atmosphere can be distracting and counterproductive.

Starting the focus group

Welcome individuals to the focus group by introducing the topic, yourself, and your co-moderator, and go over any ground rules or suggestions for a successful discussion. It’s important to make your participants feel at ease and forthcoming with their responses.

Consider starting out with an icebreaker, which will allow participants to relax and settle into the space a bit. Your icebreaker can be related to your study topic or not; it’s just an exercise to get participants talking.

Leading the discussion

Once you start asking your questions, try to keep response times equal between participants. Take note of the most and least talkative members of the group, as well as any participants with particularly strong or dominant personalities.

You can ask less talkative members questions directly to encourage them to participate or ask participants questions by name to even the playing field. Feel free to ask participants to elaborate on their answers or to give an example.

As a moderator, strive to remain neutral . Refrain from reacting to responses, and be aware of your body language (e.g., nodding, raising eyebrows) and the possibility for observer bias . Active listening skills, such as parroting back answers or asking for clarification, are good methods to encourage participation and signal that you’re listening.

Many focus groups offer a monetary incentive for participants. Depending on your research budget, this is a nice way to show appreciation for their time and commitment. To keep everyone feeling fresh, consider offering snacks or drinks as well.

After concluding your focus group, you and your co-moderator should debrief, recording initial impressions of the discussion as well as any highlights, issues, or immediate conclusions you’ve drawn.

The next step is to transcribe and clean your data . Assign each participant a number or pseudonym for organizational purposes. Transcribe the recordings and conduct content analysis to look for themes or categories of responses. The categories you choose can then form the basis for reporting your results.

Just like other research methods, focus groups come with advantages and disadvantages.

• They are fairly straightforward to organize and results have strong face validity .
• They are usually inexpensive, even if you compensate participant.
• A focus group is much less time-consuming than a survey or experiment , and you get immediate results.
• Focus group results are often more comprehensible and intuitive than raw data.

Disadvantages

• It can be difficult to assemble a truly representative sample. Focus groups are generally not considered externally valid due to their small sample sizes.
• Due to the small sample size, you cannot ensure the anonymity of respondents, which may influence their desire to speak freely.
• Depth of analysis can be a concern, as it can be challenging to get honest opinions on controversial topics.
• There is a lot of room for error in the data analysis and high potential for observer dependency in drawing conclusions. You have to be careful not to cherry-pick responses to fit a prior conclusion.

A focus group is a research method that brings together a small group of people to answer questions in a moderated setting. The group is chosen due to predefined demographic traits, and the questions are designed to shed light on a topic of interest. It is one of 4 types of interviews .

As a rule of thumb, questions related to thoughts, beliefs, and feelings work well in focus groups. Take your time formulating strong questions, paying special attention to phrasing. Be careful to avoid leading questions , which can bias your responses.

There are various approaches to qualitative data analysis , but they all share five steps in common:

• Prepare and organize your data.
• Review and explore your data.
• Develop a data coding system.
• Assign codes to the data.
• Identify recurring themes.

The specifics of each step depend on the focus of the analysis. Some common approaches include textual analysis , thematic analysis , and discourse analysis .

Every dataset requires different techniques to clean dirty data , but you need to address these issues in a systematic way. You focus on finding and resolving data points that don’t agree or fit with the rest of your dataset.

These data might be missing values, outliers, duplicate values, incorrectly formatted, or irrelevant. You’ll start with screening and diagnosing your data. Then, you’ll often standardize and accept or remove data to make your dataset consistent and valid.

The four most common types of interviews are:

• Structured interviews : The questions are predetermined in both topic and order. 
• Focus group interviews : The questions are presented to a group instead of one individual.

It’s impossible to completely avoid observer bias in studies where data collection is done or recorded manually, but you can take steps to reduce this type of bias in your research .

Scope of research is determined at the beginning of your research process , prior to the data collection stage. Sometimes called “scope of study,” your scope delineates what will and will not be covered in your project. It helps you focus your work and your time, ensuring that you’ll be able to achieve your goals and outcomes.

Defining a scope can be very useful in any research project, from a research proposal to a thesis or dissertation . A scope is needed for all types of research: quantitative , qualitative , and mixed methods .

To define your scope of research, consider the following:

• Budget constraints or any specifics of grant funding
• Your proposed timeline and duration
• Specifics about your population of study, your proposed sample size , and the research methodology you’ll pursue
• Any inclusion and exclusion criteria
• Any anticipated control , extraneous , or confounding variables that could bias your research if not accounted for properly.

Highlights that qualitative research is used increasingly in dentistry. Interviews and focus groups remain the most common qualitative methods of data collection.

Suggests the advent of digital technologies has transformed how qualitative research can now be undertaken.

Suggests interviews and focus groups can offer significant, meaningful insight into participants' experiences, beliefs and perspectives, which can help to inform developments in dental practice.

Qualitative research is used increasingly in dentistry, due to its potential to provide meaningful, in-depth insights into participants' experiences, perspectives, beliefs and behaviours. These insights can subsequently help to inform developments in dental practice and further related research. The most common methods of data collection used in qualitative research are interviews and focus groups. While these are primarily conducted face-to-face, the ongoing evolution of digital technologies, such as video chat and online forums, has further transformed these methods of data collection. This paper therefore discusses interviews and focus groups in detail, outlines how they can be used in practice, how digital technologies can further inform the data collection process, and what these methods can offer dentistry.

Introduction

Traditionally, research in dentistry has primarily been quantitative in nature. 1 However, in recent years, there has been a growing interest in qualitative research within the profession, due to its potential to further inform developments in practice, policy, education and training. Consequently, in 2008, the British Dental Journal (BDJ) published a four paper qualitative research series, 2 , 3 , 4 , 5 to help increase awareness and understanding of this particular methodological approach.

Since the papers were originally published, two scoping reviews have demonstrated the ongoing proliferation in the use of qualitative research within the field of oral healthcare. 1 , 6 To date, the original four paper series continue to be well cited and two of the main papers remain widely accessed among the BDJ readership. 2 , 3 The potential value of well-conducted qualitative research to evidence-based practice is now also widely recognised by service providers, policy makers, funding bodies and those who commission, support and use healthcare research.

Besides increasing standalone use, qualitative methods are now also routinely incorporated into larger mixed method study designs, such as clinical trials, as they can offer additional, meaningful insights into complex problems that simply could not be provided by quantitative methods alone. Qualitative methods can also be used to further facilitate in-depth understanding of important aspects of clinical trial processes, such as recruitment. For example, Ellis et al . investigated why edentulous older patients, dissatisfied with conventional dentures, decline implant treatment, despite its established efficacy, and frequently refuse to participate in related randomised clinical trials, even when financial constraints are removed. 7 Through the use of focus groups in Canada and the UK, the authors found that fears of pain and potential complications, along with perceived embarrassment, exacerbated by age, are common reasons why older patients typically refuse dental implants. 7

The last decade has also seen further developments in qualitative research, due to the ongoing evolution of digital technologies. These developments have transformed how researchers can access and share information, communicate and collaborate, recruit and engage participants, collect and analyse data and disseminate and translate research findings. 8 Where appropriate, such technologies are therefore capable of extending and enhancing how qualitative research is undertaken. 9 For example, it is now possible to collect qualitative data via instant messaging, email or online/video chat, using appropriate online platforms.

These innovative approaches to research are therefore cost-effective, convenient, reduce geographical constraints and are often useful for accessing 'hard to reach' participants (for example, those who are immobile or socially isolated). 8 , 9 However, digital technologies are still relatively new and constantly evolving and therefore present a variety of pragmatic and methodological challenges. Furthermore, given their very nature, their use in many qualitative studies and/or with certain participant groups may be inappropriate and should therefore always be carefully considered. While it is beyond the scope of this paper to provide a detailed explication regarding the use of digital technologies in qualitative research, insight is provided into how such technologies can be used to facilitate the data collection process in interviews and focus groups.

In light of such developments, it is perhaps therefore timely to update the main paper 3 of the original BDJ series. As with the previous publications, this paper has been purposely written in an accessible style, to enhance readability, particularly for those who are new to qualitative research. While the focus remains on the most common qualitative methods of data collection – interviews and focus groups – appropriate revisions have been made to provide a novel perspective, and should therefore be helpful to those who would like to know more about qualitative research. This paper specifically focuses on undertaking qualitative research with adult participants only.

Overview of qualitative research

Qualitative research is an approach that focuses on people and their experiences, behaviours and opinions. 10 , 11 The qualitative researcher seeks to answer questions of 'how' and 'why', providing detailed insight and understanding, 11 which quantitative methods cannot reach. 12 Within qualitative research, there are distinct methodologies influencing how the researcher approaches the research question, data collection and data analysis. 13 For example, phenomenological studies focus on the lived experience of individuals, explored through their description of the phenomenon. Ethnographic studies explore the culture of a group and typically involve the use of multiple methods to uncover the issues. 14

While methodology is the 'thinking tool', the methods are the 'doing tools'; 13 the ways in which data are collected and analysed. There are multiple qualitative data collection methods, including interviews, focus groups, observations, documentary analysis, participant diaries, photography and videography. Two of the most commonly used qualitative methods are interviews and focus groups, which are explored in this article. The data generated through these methods can be analysed in one of many ways, according to the methodological approach chosen. A common approach is thematic data analysis, involving the identification of themes and subthemes across the data set. Further information on approaches to qualitative data analysis has been discussed elsewhere. 1

Qualitative research is an evolving and adaptable approach, used by different disciplines for different purposes. Traditionally, qualitative data, specifically interviews, focus groups and observations, have been collected face-to-face with participants. In more recent years, digital technologies have contributed to the ongoing evolution of qualitative research. Digital technologies offer researchers different ways of recruiting participants and collecting data, and offer participants opportunities to be involved in research that is not necessarily face-to-face.

Research interviews are a fundamental qualitative research method 15 and are utilised across methodological approaches. Interviews enable the researcher to learn in depth about the perspectives, experiences, beliefs and motivations of the participant. 3 , 16 Examples include, exploring patients' perspectives of fear/anxiety triggers in dental treatment, 17 patients' experiences of oral health and diabetes, 18 and dental students' motivations for their choice of career. 19

Interviews may be structured, semi-structured or unstructured, 3 according to the purpose of the study, with less structured interviews facilitating a more in depth and flexible interviewing approach. 20 Structured interviews are similar to verbal questionnaires and are used if the researcher requires clarification on a topic; however they produce less in-depth data about a participant's experience. 3 Unstructured interviews may be used when little is known about a topic and involves the researcher asking an opening question; 3 the participant then leads the discussion. 20 Semi-structured interviews are commonly used in healthcare research, enabling the researcher to ask predetermined questions, 20 while ensuring the participant discusses issues they feel are important.

Interviews can be undertaken face-to-face or using digital methods when the researcher and participant are in different locations. Audio-recording the interview, with the consent of the participant, is essential for all interviews regardless of the medium as it enables accurate transcription; the process of turning the audio file into a word-for-word transcript. This transcript is the data, which the researcher then analyses according to the chosen approach.

Types of interview

Qualitative studies often utilise one-to-one, face-to-face interviews with research participants. This involves arranging a mutually convenient time and place to meet the participant, signing a consent form and audio-recording the interview. However, digital technologies have expanded the potential for interviews in research, enabling individuals to participate in qualitative research regardless of location.

Telephone interviews can be a useful alternative to face-to-face interviews and are commonly used in qualitative research. They enable participants from different geographical areas to participate and may be less onerous for participants than meeting a researcher in person. 15 A qualitative study explored patients' perspectives of dental implants and utilised telephone interviews due to the quality of the data that could be yielded. 21 The researcher needs to consider how they will audio record the interview, which can be facilitated by purchasing a recorder that connects directly to the telephone. One potential disadvantage of telephone interviews is the inability of the interviewer and researcher to see each other. This is resolved using software for audio and video calls online – such as Skype – to conduct interviews with participants in qualitative studies. Advantages of this approach include being able to see the participant if video calls are used, enabling observation of non-verbal communication, and the software can be free to use. However, participants are required to have a device and internet connection, as well as being computer literate, potentially limiting who can participate in the study. One qualitative study explored the role of dental hygienists in reducing oral health disparities in Canada. 22 The researcher conducted interviews using Skype, which enabled dental hygienists from across Canada to be interviewed within the research budget, accommodating the participants' schedules. 22

A less commonly used approach to qualitative interviews is the use of social virtual worlds. A qualitative study accessed a social virtual world – Second Life – to explore the health literacy skills of individuals who use social virtual worlds to access health information. 23 The researcher created an avatar and interview room, and undertook interviews with participants using voice and text methods. 23 This approach to recruitment and data collection enables individuals from diverse geographical locations to participate, while remaining anonymous if they wish. Furthermore, for interviews conducted using text methods, transcription of the interview is not required as the researcher can save the written conversation with the participant, with the participant's consent. However, the researcher and participant need to be familiar with how the social virtual world works to engage in an interview this way.

Conducting an interview

Ensuring informed consent before any interview is a fundamental aspect of the research process. Participants in research must be afforded autonomy and respect; consent should be informed and voluntary. 24 Individuals should have the opportunity to read an information sheet about the study, ask questions, understand how their data will be stored and used, and know that they are free to withdraw at any point without reprisal. The qualitative researcher should take written consent before undertaking the interview. In a face-to-face interview, this is straightforward: the researcher and participant both sign copies of the consent form, keeping one each. However, this approach is less straightforward when the researcher and participant do not meet in person. A recent protocol paper outlined an approach for taking consent for telephone interviews, which involved: audio recording the participant agreeing to each point on the consent form; the researcher signing the consent form and keeping a copy; and posting a copy to the participant. 25 This process could be replicated in other interview studies using digital methods.

There are advantages and disadvantages of using face-to-face and digital methods for research interviews. Ultimately, for both approaches, the quality of the interview is determined by the researcher. 16 Appropriate training and preparation are thus required. Healthcare professionals can use their interpersonal communication skills when undertaking a research interview, particularly questioning, listening and conversing. 3 However, the purpose of an interview is to gain information about the study topic, 26 rather than offering help and advice. 3 The researcher therefore needs to listen attentively to participants, enabling them to describe their experience without interruption. 3 The use of active listening skills also help to facilitate the interview. 14 Spradley outlined elements and strategies for research interviews, 27 which are a useful guide for qualitative researchers:

Greeting and explaining the project/interview

Asking descriptive (broad), structural (explore response to descriptive) and contrast (difference between) questions

Asymmetry between the researcher and participant talking

Expressing interest and cultural ignorance

Repeating, restating and incorporating the participant's words when asking questions

Creating hypothetical situations

Asking friendly questions

Knowing when to leave.

For semi-structured interviews, a topic guide (also called an interview schedule) is used to guide the content of the interview – an example of a topic guide is outlined in Box 1 . The topic guide, usually based on the research questions, existing literature and, for healthcare professionals, their clinical experience, is developed by the research team. The topic guide should include open ended questions that elicit in-depth information, and offer participants the opportunity to talk about issues important to them. This is vital in qualitative research where the researcher is interested in exploring the experiences and perspectives of participants. It can be useful for qualitative researchers to pilot the topic guide with the first participants, 10 to ensure the questions are relevant and understandable, and amending the questions if required.

Regardless of the medium of interview, the researcher must consider the setting of the interview. For face-to-face interviews, this could be in the participant's home, in an office or another mutually convenient location. A quiet location is preferable to promote confidentiality, enable the researcher and participant to concentrate on the conversation, and to facilitate accurate audio-recording of the interview. For interviews using digital methods the same principles apply: a quiet, private space where the researcher and participant feel comfortable and confident to participate in an interview.

Focus groups

A focus group is a moderated group discussion on a pre-defined topic, for research purposes. 28 , 29 While not aligned to a particular qualitative methodology (for example, grounded theory or phenomenology) as such, focus groups are used increasingly in healthcare research, as they are useful for exploring collective perspectives, attitudes, behaviours and experiences. Consequently, they can yield rich, in-depth data and illuminate agreement and inconsistencies 28 within and, where appropriate, between groups. Examples include public perceptions of dental implants and subsequent impact on help-seeking and decision making, 30 and general dental practitioners' views on patient safety in dentistry. 31

Focus groups can be used alone or in conjunction with other methods, such as interviews or observations, and can therefore help to confirm, extend or enrich understanding and provide alternative insights. 28 The social interaction between participants often results in lively discussion and can therefore facilitate the collection of rich, meaningful data. However, they are complex to organise and manage, due to the number of participants, and may also be inappropriate for exploring particularly sensitive issues that many participants may feel uncomfortable about discussing in a group environment.

Focus groups are primarily undertaken face-to-face but can now also be undertaken online, using appropriate technologies such as email, bulletin boards, online research communities, chat rooms, discussion forums, social media and video conferencing. 32 Using such technologies, data collection can also be synchronous (for example, online discussions in 'real time') or, unlike traditional face-to-face focus groups, asynchronous (for example, online/email discussions in 'non-real time'). While many of the fundamental principles of focus group research are the same, regardless of how they are conducted, a number of subtle nuances are associated with the online medium. 32 Some of which are discussed further in the following sections.

Focus group considerations

Some key considerations associated with face-to-face focus groups are: how many participants are required; should participants within each group know each other (or not) and how many focus groups are needed within a single study? These issues are much debated and there is no definitive answer. However, the number of focus groups required will largely depend on the topic area, the depth and breadth of data needed, the desired level of participation required 29 and the necessity (or not) for data saturation.

The optimum group size is around six to eight participants (excluding researchers) but can work effectively with between three and 14 participants. 3 If the group is too small, it may limit discussion, but if it is too large, it may become disorganised and difficult to manage. It is, however, prudent to over-recruit for a focus group by approximately two to three participants, to allow for potential non-attenders. For many researchers, particularly novice researchers, group size may also be informed by pragmatic considerations, such as the type of study, resources available and moderator experience. 28 Similar size and mix considerations exist for online focus groups. Typically, synchronous online focus groups will have around three to eight participants but, as the discussion does not happen simultaneously, asynchronous groups may have as many as 10–30 participants. 33

The topic area and potential group interaction should guide group composition considerations. Pre-existing groups, where participants know each other (for example, work colleagues) may be easier to recruit, have shared experiences and may enjoy a familiarity, which facilitates discussion and/or the ability to challenge each other courteously. 3 However, if there is a potential power imbalance within the group or if existing group norms and hierarchies may adversely affect the ability of participants to speak freely, then 'stranger groups' (that is, where participants do not already know each other) may be more appropriate. 34 , 35

Focus group management

Face-to-face focus groups should normally be conducted by two researchers; a moderator and an observer. 28 The moderator facilitates group discussion, while the observer typically monitors group dynamics, behaviours, non-verbal cues, seating arrangements and speaking order, which is essential for transcription and analysis. The same principles of informed consent, as discussed in the interview section, also apply to focus groups, regardless of medium. However, the consent process for online discussions will probably be managed somewhat differently. For example, while an appropriate participant information leaflet (and consent form) would still be required, the process is likely to be managed electronically (for example, via email) and would need to specifically address issues relating to technology (for example, anonymity and use, storage and access to online data). 32

The venue in which a face to face focus group is conducted should be of a suitable size, private, quiet, free from distractions and in a collectively convenient location. It should also be conducted at a time appropriate for participants, 28 as this is likely to promote attendance. As with interviews, the same ethical considerations apply (as discussed earlier). However, online focus groups may present additional ethical challenges associated with issues such as informed consent, appropriate access and secure data storage. Further guidance can be found elsewhere. 8 , 32

Before the focus group commences, the researchers should establish rapport with participants, as this will help to put them at ease and result in a more meaningful discussion. Consequently, researchers should introduce themselves, provide further clarity about the study and how the process will work in practice and outline the 'ground rules'. Ground rules are designed to assist, not hinder, group discussion and typically include: 3 , 28 , 29

Discussions within the group are confidential to the group

Only one person can speak at a time

All participants should have sufficient opportunity to contribute

There should be no unnecessary interruptions while someone is speaking

Everyone can be expected to be listened to and their views respected

Challenging contrary opinions is appropriate, but ridiculing is not.

Moderating a focus group requires considered management and good interpersonal skills to help guide the discussion and, where appropriate, keep it sufficiently focused. Avoid, therefore, participating, leading, expressing personal opinions or correcting participants' knowledge 3 , 28 as this may bias the process. A relaxed, interested demeanour will also help participants to feel comfortable and promote candid discourse. Moderators should also prevent the discussion being dominated by any one person, ensure differences of opinions are discussed fairly and, if required, encourage reticent participants to contribute. 3 Asking open questions, reflecting on significant issues, inviting further debate, probing responses accordingly, and seeking further clarification, as and where appropriate, will help to obtain sufficient depth and insight into the topic area.

Moderating online focus groups requires comparable skills, particularly if the discussion is synchronous, as the discussion may be dominated by those who can type proficiently. 36 It is therefore important that sufficient time and respect is accorded to those who may not be able to type as quickly. Asynchronous discussions are usually less problematic in this respect, as interactions are less instant. However, moderating an asynchronous discussion presents additional challenges, particularly if participants are geographically dispersed, as they may be online at different times. Consequently, the moderator will not always be present and the discussion may therefore need to occur over several days, which can be difficult to manage and facilitate and invariably requires considerable flexibility. 32 It is also worth recognising that establishing rapport with participants via online medium is often more challenging than via face-to-face and may therefore require additional time, skills, effort and consideration.

As with research interviews, focus groups should be guided by an appropriate interview schedule, as discussed earlier in the paper. For example, the schedule will usually be informed by the review of the literature and study aims, and will merely provide a topic guide to help inform subsequent discussions. To provide a verbatim account of the discussion, focus groups must be recorded, using an audio-recorder with a good quality multi-directional microphone. While videotaping is possible, some participants may find it obtrusive, 3 which may adversely affect group dynamics. The use (or not) of a video recorder, should therefore be carefully considered.

At the end of the focus group, a few minutes should be spent rounding up and reflecting on the discussion. 28 Depending on the topic area, it is possible that some participants may have revealed deeply personal issues and may therefore require further help and support, such as a constructive debrief or possibly even referral on to a relevant third party. It is also possible that some participants may feel that the discussion did not adequately reflect their views and, consequently, may no longer wish to be associated with the study. 28 Such occurrences are likely to be uncommon, but should they arise, it is important to further discuss any concerns and, if appropriate, offer them the opportunity to withdraw (including any data relating to them) from the study. Immediately after the discussion, researchers should compile notes regarding thoughts and ideas about the focus group, which can assist with data analysis and, if appropriate, any further data collection.

Qualitative research is increasingly being utilised within dental research to explore the experiences, perspectives, motivations and beliefs of participants. The contributions of qualitative research to evidence-based practice are increasingly being recognised, both as standalone research and as part of larger mixed-method studies, including clinical trials. Interviews and focus groups remain commonly used data collection methods in qualitative research, and with the advent of digital technologies, their utilisation continues to evolve. However, digital methods of qualitative data collection present additional methodological, ethical and practical considerations, but also potentially offer considerable flexibility to participants and researchers. Consequently, regardless of format, qualitative methods have significant potential to inform important areas of dental practice, policy and further related research.

Focus Groups

Focus groups bring individuals from the study population together in a specific setting in order to discuss an issue as a group. The discussion generates research data.

Focus groups typically have these features:

• Four to ten participants meeting for up to two hours
• A facilitator or facilitators to guide discussion using open-ended questions
• An emphasis on the group talking among itself rather than to the facilitator
• Discussion is recorded and then transcribed for analysis by researchers

Researchers conduct several individual focus group meetings to produce a series. The number of focus groups in the series depends on the study’s aim, methods and resources.

Focus groups use a group setting to generate data different to that obtained in a one-to-one interview. The group context may allow for better examination of beliefs, attitudes, values, perspectives, knowledge and ideas.

Focus groups can be useful in action research methodology and other study designs which seek to empower research participants. Focus groups are also useful in multimethod studies utilising different forms of data collection.

• Quick way to collect data from several people 
• Produces data unique to group setting (e.g. teasing, arguing and non-verbal behaviour) due to the interaction between participants. This is a unique feature of focus groups. 
• Unlike written questionnaires, focus groups don’t rely on participant literacy to generate data 
• Can encourage participation from marginalised groups 
• Can facilitate discussion of stigmatised or counter-cultural topics due to feeling of mutual support among focus group participants 
• Can generate more critical comments than individual interviews. This is valuable for research aimed at improving products or services. 
• Can be used to validate findings from quantitative research methods by providing a deeper understanding that statistics cannot.

Limitations

• Individual perspectives that dissent from the focus group’s majority may remain hidden due to overriding behavioural or cultural norms, or a desire to be seen as conforming. 
• Confidentiality of individual responses is compromised due to the existence of the group 
• Only applicable when the population of interest has shared social and cultural experience or share common areas of concern. 
• Group discussion does not provide enough depth for researchers to understand experiences, especially in comparison to in-depth interviews. 
• Data is representative of the range of views in a population, not the prevalence of such views. 
• The facilitator has a strong effect on the focus groups behaviour and can therefore influence the extent to which issues or views are explored. 
• Data analysis is usually very time consuming due to the quantity produced.

Example questions

• What are the experiences, needs and wishes of mothers who received midwifery care at tertiary hospitals in Victoria, Australia?
• How useful is the patient perspective for the creation of an information information booklet for patients with liver cancer?
• What factors influence nursing students' development of end-of-life communication skills?

Focus Group

Definition:

A focus group is a qualitative research method used to gather in-depth insights and opinions from a group of individuals about a particular product, service, concept, or idea.

The focus group typically consists of 6-10 participants who are selected based on shared characteristics such as demographics, interests, or experiences. The discussion is moderated by a trained facilitator who asks open-ended questions to encourage participants to share their thoughts, feelings, and attitudes towards the topic.

Focus groups are an effective way to gather detailed information about consumer behavior, attitudes, and perceptions, and can provide valuable insights to inform decision-making in a range of fields including marketing, product development, and public policy.

Types of Focus Group

The following are some types or methods of Focus Groups:

Traditional Focus Group

This is the most common type of focus group, where a small group of people is brought together to discuss a particular topic. The discussion is typically led by a skilled facilitator who asks open-ended questions to encourage participants to share their thoughts and opinions.

Mini Focus Group

A mini-focus group involves a smaller group of participants, typically 3 to 5 people. This type of focus group is useful when the topic being discussed is particularly sensitive or when the participants are difficult to recruit.

Dual Moderator Focus Group

In a dual-moderator focus group, two facilitators are used to manage the discussion. This can help to ensure that the discussion stays on track and that all participants have an opportunity to share their opinions.

Teleconference or Online Focus Group

Teleconferences or online focus groups are conducted using video conferencing technology or online discussion forums. This allows participants to join the discussion from anywhere in the world, making it easier to recruit participants and reducing the cost of conducting the focus group.

Client-led Focus Group

In a client-led focus group, the client who is commissioning the research takes an active role in the discussion. This type of focus group is useful when the client has specific questions they want to ask or when they want to gain a deeper understanding of their customers.

The following Table can explain Focus Group types more clearly

How To Conduct a Focus Group

To conduct a focus group, follow these general steps:

Define the Research Question

Identify the key research question or objective that you want to explore through the focus group. Develop a discussion guide that outlines the topics and questions you want to cover during the session.

Recruit Participants

Identify the target audience for the focus group and recruit participants who meet the eligibility criteria. You can use various recruitment methods such as social media, online panels, or referrals from existing customers.

Select a Venue

Choose a location that is convenient for the participants and has the necessary facilities such as audio-visual equipment, seating, and refreshments.

Conduct the Session

During the focus group session, introduce the topic, and review the objectives of the research. Encourage participants to share their thoughts and opinions by asking open-ended questions and probing deeper into their responses. Ensure that the discussion remains on topic and that all participants have an opportunity to contribute.

Record the Session

Use audio or video recording equipment to capture the discussion. Note-taking is also essential to ensure that you capture all key points and insights.

Analyze the data

Once the focus group is complete, transcribe and analyze the data. Look for common themes, patterns, and insights that emerge from the discussion. Use this information to generate insights and recommendations that can be applied to the research question.

When to use Focus Group Method

The focus group method is typically used in the following situations:

Exploratory Research

When a researcher wants to explore a new or complex topic in-depth, focus groups can be used to generate ideas, opinions, and insights.

Product Development

Focus groups are often used to gather feedback from consumers about new products or product features to help identify potential areas for improvement.

Marketing Research

Focus groups can be used to test marketing concepts, messaging, or advertising campaigns to determine their effectiveness and appeal to different target audiences.

Customer Feedback

Focus groups can be used to gather feedback from customers about their experiences with a particular product or service, helping companies improve customer satisfaction and loyalty.

Public Policy Research

Focus groups can be used to gather public opinions and attitudes on social or political issues, helping policymakers make more informed decisions.

Examples of Focus Group

Here are some real-time examples of focus groups:

• A tech company wants to improve the user experience of their mobile app. They conduct a focus group with a diverse group of users to gather feedback on the app’s design, functionality, and features. The focus group consists of 8 participants who are selected based on their age, gender, ethnicity, and level of experience with the app. During the session, a trained facilitator asks open-ended questions to encourage participants to share their thoughts and opinions on the app. The facilitator also observes the participants’ behavior and reactions to the app’s features. After the focus group, the data is analyzed to identify common themes and issues raised by the participants. The insights gathered from the focus group are used to inform improvements to the app’s design and functionality, with the goal of creating a more user-friendly and engaging experience for all users.
• A car manufacturer wants to develop a new electric vehicle that appeals to a younger demographic. They conduct a focus group with millennials to gather their opinions on the design, features, and pricing of the vehicle.
• A political campaign team wants to develop effective messaging for their candidate’s campaign. They conduct a focus group with voters to gather their opinions on key issues and identify the most persuasive arguments and messages.
• A restaurant chain wants to develop a new menu that appeals to health-conscious customers. They conduct a focus group with fitness enthusiasts to gather their opinions on the types of food and drinks that they would like to see on the menu.
• A healthcare organization wants to develop a new wellness program for their employees. They conduct a focus group with employees to gather their opinions on the types of programs, incentives, and support that would be most effective in promoting healthy behaviors.
• A clothing retailer wants to develop a new line of sustainable and eco-friendly clothing. They conduct a focus group with environmentally conscious consumers to gather their opinions on the design, materials, and pricing of the clothing.

Purpose of Focus Group

The key objectives of a focus group include:

Generating New Ideas and insights

Focus groups are used to explore new or complex topics in-depth, generating new ideas and insights that may not have been previously considered.

Understanding Consumer Behavior

Focus groups can be used to gather information on consumer behavior, attitudes, and perceptions to inform marketing and product development strategies.

Testing Concepts and Ideas

Focus groups can be used to test marketing concepts, messaging, or product prototypes to determine their effectiveness and appeal to different target audiences.

Gathering Customer Feedback

Informing decision-making.

Focus groups can provide valuable insights to inform decision-making in a range of fields including marketing, product development, and public policy.

Advantages of Focus Group

The advantages of using focus groups are:

• In-depth insights: Focus groups provide in-depth insights into the attitudes, opinions, and behaviors of a target audience on a specific topic, allowing researchers to gain a deeper understanding of the issues being explored.
• Group dynamics: The group dynamics of focus groups can provide additional insights, as participants may build on each other’s ideas, share experiences, and debate different perspectives.
• Efficient data collection: Focus groups are an efficient way to collect data from multiple individuals at the same time, making them a cost-effective method of research.
• Flexibility : Focus groups can be adapted to suit a range of research objectives, from exploratory research to concept testing and customer feedback.
• Real-time feedback: Focus groups provide real-time feedback on new products or concepts, allowing researchers to make immediate adjustments and improvements based on participant feedback.
• Participant engagement: Focus groups can be a more engaging and interactive research method than surveys or other quantitative methods, as participants have the opportunity to express their opinions and interact with other participants.

Limitations of Focus Groups

While focus groups can provide valuable insights, there are also some limitations to using them.

• Small sample size: Focus groups typically involve a small number of participants, which may not be representative of the broader population being studied.
• Group dynamics : While group dynamics can be an advantage of focus groups, they can also be a limitation, as dominant personalities may sway the discussion or participants may not feel comfortable expressing their true opinions.
• Limited generalizability : Because focus groups involve a small sample size, the results may not be generalizable to the broader population.
• Limited depth of responses: Because focus groups are time-limited, participants may not have the opportunity to fully explore or elaborate on their opinions or experiences.
• Potential for bias: The facilitator of a focus group may inadvertently influence the discussion or the selection of participants may not be representative, leading to potential bias in the results.
• Difficulty in analysis : The qualitative data collected in focus groups can be difficult to analyze, as it is often subjective and requires a skilled researcher to interpret and identify themes.

Characteristics of Focus Group

• Small group size: Focus groups typically involve a small number of participants, ranging from 6 to 12 people. This allows for a more in-depth and focused discussion.
• Targeted participants: Participants in focus groups are selected based on specific criteria, such as age, gender, or experience with a particular product or service.
• Facilitated discussion: A skilled facilitator leads the discussion, asking open-ended questions and encouraging participants to share their thoughts and experiences.
• I nteractive and conversational: Focus groups are interactive and conversational, with participants building on each other’s ideas and responding to one another’s opinions.
• Qualitative data: The data collected in focus groups is qualitative, providing detailed insights into participants’ attitudes, opinions, and behaviors.
• Non-threatening environment: Participants are encouraged to share their thoughts and experiences in a non-threatening and supportive environment.
• Limited time frame: Focus groups are typically time-limited, lasting between 1 and 2 hours, to ensure that the discussion stays focused and productive.

A focus group is a qualitative research method that involves facilitating a small group discussion with participants who share common characteristics or experiences that are relevant to the research topic. The goal is to gain insights through group conversation and observation of dynamics.

In a focus group:

• A moderator asks questions and leads a group of typically 6 to 12 pre-screened participants through a discussion focused on a particular topic.
• Group members are encouraged to talk with one another, exchange anecdotes, comment on each others’ experiences and points of view, and build on each others’ responses.
• The goal is to create a candid, natural conversation that provides insights into the participants’ perceptions, attitudes, beliefs, and opinions on the topic.
• Focus groups capitalize on group dynamics to elicit multiple perspectives in a social environment as participants are influenced by and influence others through open discussion.
• The interactive responses allow researchers to quickly gather more contextual, nuanced qualitative data compared to surveys or one-on-one interviews.

Focus groups allow researchers to gather perspectives from multiple people at once in an interactive group setting. This group dynamic surfaces richer responses as participants build on each other’s comments, discuss issues in-depth, and voice agreements or disagreements.

It is important that participants feel comfortable expressing diverse viewpoints rather than being pressured into a consensus.

Focus groups emerged as an alternative to questionnaires in the 1930s over concerns that surveys fostered passive responses or failed to capture people’s authentic perspectives.

During World War II, focus groups were used to evaluate military morale-boosting radio programs. By the 1950s focus groups became widely adopted in marketing research to test consumer preferences.

A key benefit K. Merton highlighted in 1956 was grouping participants with shared knowledge of a topic. This common grounding enables people to provide context to their experiences and allows contrasts between viewpoints to emerge across the group.

As a result, focus groups can elicit a wider range of perspectives than one-on-one interviews.

Step 1 : Clarify the Focus Group’s Purpose and Orientation

Clarify the purpose and orientation of the focus group (Tracy, 2013). Carefully consider whether a focus group or individual interviews will provide the type of qualitative data needed to address your research questions.

Determine if the interactive, fast-paced group discussion format is aligned with gathering perspectives vs. in-depth attitudes on a topic.

Consider incorporating special techniques like extended focus groups with pre-surveys, touchstones using creative imagery/metaphors to focus the topic, or bracketing through ongoing conceptual inspection.

For example

A touchstone in a focus group refers to using a shared experience, activity, metaphor, or other creative technique to provide a common reference point and orientation for grounding the discussion.

The purpose of Mulvale et al. (2021) was to understand the hospital experiences of youth after suicide attempts.

The researchers created a touchstone to focus the discussion specifically around the hospital visit. This provided a shared orientation for the vulnerable participants to open up about their emotional journeys.

In the example from Mulvale et al. (2021), the researchers designated the hospital visit following suicide attempts as the touchstone. This means:

• The visit served as a defining shared experience all youth participants could draw upon to guide the focus group discussion, since they unfortunately had this in common.
• Framing questions around recounting and making meaning out of the hospitalization focused the conversation to elicit rich details about interactions, emotions, challenges, supports needed, and more in relation to this watershed event.
• The hospital visit as a touchstone likely resonated profoundly across youth given the intensity and vulnerability surrounding their suicide attempts. This deepened their willingness to open up and established group rapport.

So in this case, the touchstone concentrated the dialogue around a common catalyst experience enabling youth to build understanding, voice difficulties, and potentially find healing through sharing their journey with empathetic peers who had endured the same trauma.

Step 2 : Select a Homogeneous Grouping Characteristic

Select a homogeneous grouping characteristic (Krueger & Casey, 2009) to recruit participants with a commonality, like shared roles, experiences, or demographics, to enable meaningful discussion.

A sample size of between 6 to 10 participants allows for adequate mingling (MacIntosh 1993).

More members may diminish the ability to capture all viewpoints. Fewer risks limited diversity of thought.

Balance recruitment across income, gender, age, and cultural factors to increase heterogeneity in perspectives. Consider screening criteria to qualify relevant participants.

Choosing focus group participants requires balancing homogeneity and diversity – too much variation across gender, class, profession, etc., can inhibit sharing, while over-similarity limits perspectives. Groups should feel mutual comfort and relevance of experience to enable open contributions while still representing a mix of viewpoints on the topic (Morgan 1988).

Mulvale et al. (2021) determined grouping by gender rather than age or ethnicity was more impactful for suicide attempt experiences.

They fostered difficult discussions by bringing together male and female youth separately based on the sensitive nature of topics like societal expectations around distress.

Step 3 : Designate a Moderator

Designate a skilled, neutral moderator (Crowe, 2003; Morgan, 1997) to steer productive dialogue given their expertise in guiding group interactions. Consider cultural insider moderators positioned to foster participant sharing by understanding community norms.

Define moderator responsibilities like directing discussion flow, monitoring air time across members, and capturing observational notes on behaviors/dynamics.

Choose whether the moderator also analyzes data or only facilitates the group.

Mulvale et al. (2021) designated a moderator experienced working with marginalized youth to encourage sharing by establishing an empathetic, non-judgmental environment through trust-building and active listening guidance.

Step 4 : Develop a Focus Group Guide

Develop an extensive focus group guide (Krueger & Casey, 2009). Include an introduction to set a relaxed tone, explain the study rationale, review confidentiality protection procedures, and facilitate a participant introduction activity.

Also include guidelines reiterating respect, listening, and sharing principles both verbally and in writing.

Group confidentiality agreement

The group context introduces distinct ethical demands around informed consent, participant expectations, confidentiality, and data treatment. Establishing guidelines at the outset helps address relevant issues.

Create a group confidentiality agreement (Berg, 2004) specifying that all comments made during the session must remain private, anonymous in data analysis, and not discussed outside the group without permission.

Have it signed, demonstrating a communal commitment to sustaining a safe, secure environment for honest sharing.

Berg (2004) recommends a formal signed agreement prohibiting participants from publicly talking about anything said in the focus group without permission. This reassures members their personal disclosures are safeguarded.

Develop questions starting general then funneling down to 10-12 key questions on critical topics. Integrate think/pair/share activities between question sets to encourage inclusion. Close with a conclusion to summarize key ideas voiced without endorsing consensus.

Krueger and Casey (2009) recommend structuring focus group questions in five stages:

Opening Questions:

• Start with easy, non-threatening questions to make participants comfortable, often related to their background and experience with the topic.
• Get everyone talking and open up initial dialogue.
• Example: “Let’s go around and have each person share how long you’ve lived in this city.”

Introductory Questions:

• Transition to the key focus group objectives and main topics of interest.
• Remain quite general to provide baseline understanding before drilling down.
• Example: “Thinking broadly, how would you describe the arts and cultural offerings in your community?”

Transition Questions:

• Serve as a logical link between introductory and key questions.
• Funnel participants toward critical topics guided by research aims.
• Example: “Specifically related to concerts and theatre performances, what venues in town have you attended events at over the past year?”

Key Questions:

• Drive at the heart of study goals, and issues under investigation.
• Ask 5-10 questions that foster organic, interactive discussion between participants.
• Example: “What enhances or detracts from the concert-going experience at these various venues?”

Ending Questions:

• Provide an opportunity for final thoughts or anything missed.
• Assess the degree of consensus on key topics.
• Example: “If you could improve just one thing about the concert and theatre options here, what would you prioritize?”

It is vital to extensively pilot test draft questions to hone the wording, flow, timing, tone and tackle any gaps to adequately cover research objectives through dynamic group discussion.

Step 5 : Prepare the focus group room

Prepare the focus group room (Krueger & Casey, 2009) attending to details like circular seating for eye contact, centralized recording equipment with backup power, name cards, and refreshments to create a welcoming, affirming environment critical for participants to feel valued, comfortable engaging in genuine dialogue as a collective.

Arrange seating comfortably in a circle to facilitate discussion flow and eye contact among members. Decide if space for breakout conversations or activities like role-playing is needed.

Refreshments

• Coordinate snacks or light refreshments to be available when focus group members arrive, especially for longer sessions. This contributes to a welcoming atmosphere.
• Even if no snacks are provided, consider making bottled water available throughout the session.
• Set out colorful pens and blank name tags for focus group members to write their preferred name or pseudonym when they arrive.
• Attaching name tags to clothing facilitates interaction and expedites learning names.
• If short on preparation time, prepare printed name tags in advance based on RSVPs, but blank name tags enable anonymity if preferred.

Krueger & Casey (2009) suggest welcoming focus group members with comfortable, inclusive seating arrangements in a circle to enable eye contact. Providing snacks and music sets a relaxed tone.

Step 6 : Conduct the focus group

Conduct the focus group utilizing moderation skills like conveying empathy, observing verbal and non-verbal cues, gently redirecting and probing overlooked members, and affirming the usefulness of knowledge sharing.

Use facilitation principles (Krueger & Casey, 2009; Tracy 2013) like ensuring psychological safety, mutual respect, equitable airtime, and eliciting an array of perspectives to expand group knowledge. Gain member buy-in through collaborative review.

Record discussions through detailed note-taking, audio/video recording, and seating charts tracking engaged participation.

The role of moderator

The moderator is critical in facilitating open, interactive discussion in the group. Their main responsibilities are:

• Providing clear explanations of the purpose and helping participants feel comfortable
• Promoting debate by asking open-ended questions
• Drawing out differences of opinion and a range of perspectives by challenging participants
• Probing for more details when needed or moving the conversation forward
• Keeping the discussion focused and on track
• Ensuring all participants get a chance to speak
• Remaining neutral and non-judgmental, without sharing personal opinions

Moderators need strong interpersonal abilities to build participant trust and comfort sharing. The degree of control and input from the moderator depends on the research goals and personal style.

With multiple moderators, roles, and responsibilities should be clear and consistent across groups. Careful preparation is key for effective moderation.

Mulvale et al. (2021) fostered psychological safety for youth to share intense emotions about suicide attempts without judgment. The moderator ensured equitable speaking opportunities within a compassionate climate.

Krueger & Casey (2009) advise moderators to handle displays of distress empathetically by offering a break and emotional support through active listening instead of ignoring reactions. This upholds ethical principles.

Advantages and disadvantages of focus groups

Focus groups efficiently provide interactive qualitative data that can yield useful insights into emerging themes. However, findings may be skewed by group behaviors and still require larger sample validation through added research methods. Careful planning is vital.

• Efficient way to gather a range of perspectives in participants’ own words in a short time
• Group dynamic encourages more complex responses as members build on others’ comments
• Can observe meaningful group interactions, consensus, or disagreements
• Flexibility for moderators to probe unanticipated insights during discussion
• Often feels more comfortable sharing as part of a group rather than one-on-one
• Helps participants recall and reflect by listening to others tell their stories

Disadvantages

• Small sample size makes findings difficult to generalize
• Groupthink: influential members may discourage dissenting views from being shared
• Social desirability bias: reluctance from participants to oppose perceived majority opinions
• Requires highly skilled moderators to foster inclusive participation and contain domineering members
• Confidentiality harder to ensure than with individual interviews
• Transcriptions may have overlapping talk that is difficult to capture accurately
• Group dynamics adds layers of complexity for analysis beyond just the content of responses

Methodological Aspects of Focus Groups in Health Research

Anja p. tausch.

1 GESIS–Leibniz Institute for the Social Sciences, Mannheim, Germany

Natalja Menold

Although focus groups are commonly used in health research to explore the perspectives of patients or health care professionals, few studies consider methodological aspects in this specific context. For this reason, we interviewed nine researchers who had conducted focus groups in the context of a project devoted to the development of an electronic personal health record. We performed qualitative content analysis on the interview data relating to recruitment, communication between the focus group participants, and appraisal of the focus group method. The interview data revealed aspects of the focus group method that are particularly relevant for health research and that should be considered in that context. They include, for example, the preferability of face-to-face recruitment, the necessity to allow participants in patient groups sufficient time to introduce themselves, and the use of methods such as participant-generated cards and prioritization.

Focus groups have been widely used in health research in recent years to explore the perspectives of patients and other groups in the health care system (e.g., Carr et al., 2003 ; Côté-Arsenault & Morrison-Beedy, 2005 ; Kitzinger, 2006 ). They are often included in mixed-methods studies to gain more information on how to construct questionnaires or interpret results ( Creswell & Plano Clark, 2007 ; Kroll, Neri, & Miller, 2005 ).

The fact that the group process helps people to identify and clarify their views is considered to be an important advantage of focus groups compared with individual interviews ( Kitzinger, 1995 ). The group functions as a promoter of synergy and spontaneity by encouraging the participants to comment, explain, disagree, and share their views. Thus, experiences are shared and opinions voiced that might not surface during individual interviews ( Carey, 1994 ; Stewart, Shamdasani, & Rook, 2007 ). Although focus groups allow participants to respond in their own words and to choose discussion topics themselves, they are not completely unstructured. Questions relating to the research topic are designed by the researchers and are used to guide the discussion ( Stewart et al., 2007 ). The degree of structure of the focus group depends on the openness of the research question(s). Hence, although it takes more time and effort to organize focus groups, and they cause greater logistical problems than individual interviews do, they might generate more ideas about, and yield deeper insights into, the problem under investigation ( Coenen, Stamm, Stucki, & Cieza, 2012 ; Kingry, Tiedje, & Friedman, 1990 ; Morgan, 2009 ).

Historically, focus groups were used mainly for market research before the method was adopted for application in qualitative research in the social sciences ( Morgan, 1996 ). The use of focus groups in health care research is even more recent. For this reason, methodological recommendations on using focus groups in the health care context are quite rare, and researchers rely mainly on general advice from the social sciences (e.g., Krueger, 1988 ; Morgan, 1993 ; Morgan & Krueger, 1998 ; Stewart et al., 2007 ). Even though focus groups have been used in a great variety of health research fields, such as patients’ treatments and perceptions in the context of specific illnesses (rheumatoid arthritis: for example, Feldthusen, Björk, Forsblad-d’Elia, & Mannerkorpi, 2013 ; cancer: for example, Gerber, Hamann, Rasco, Woodruff, & Lee, 2012 ; diabetes: for example, Nafees, Lloyd, Kennedy-Martin, & Hynd, 2006 ; heart failure: for example, Rasmusson et al., 2014 ), community health research (e.g., Daley et al., 2010 ; Rhodes, Hergenrather, Wilkin, Alegría-Ortega, & Montaño, 2006 ), or invention of new diagnostic or therapeutic methods (e.g., Vincent, Clark, Marquez Zimmer, & Sanchez, 2006 ), the method and its particular use in health research is rarely reflected. Methodological articles about the focus group method in health care journals mainly summarize general advice from the social sciences (e.g., Kingry et al., 1990 ; Kitzinger, 1995 , 2006 ), while field-specific aspects of the target groups (patients, doctors, other medical staff) and the research questions (not only sociological but often also medical or technical) are seldom addressed. Reports on participant recruitment and methods of conducting the focus groups are primarily episodic in nature (e.g., Coenen et al., 2012 ; Côté-Arsenault & Morrison-Beedy, 2005 ) and often focus on very specific aspects of the method (communication: for example, Lehoux, Poland, & Daudelin, 2006 ; activating methods: for example, Colucci, 2007 ) or aim at a comparison between face-to-face focus groups and other methods (individual interviews: for example, Coenen et al., 2012 ; telephone groups: for example, Frazier et al., 2010 ; Internet groups: for example, Nicholas et al., 2010 ). Thus, systematic reviews of factors influencing the results of focus groups as well as advantages, disadvantages, and pitfalls are missing. One consequence is that researchers might find it difficult to recruit enough participants or might be surprised by the communication styles of the target groups. Furthermore, in the tradition of classical clinical research, the group discussions might result in a question-and-answer situation or “resemble individual interviews done in group settings” ( Colucci, 2007 , p. 1,424), thereby missing out on the opportunity to use the group setting to activate all participants and to encourage a deeper elaboration of their ideas. Colucci, for example, proposed the use of exercises (e.g., activity-oriented questions) to focus the attention of the group on the core topic and to facilitate subsequent analyses.

Recommendations from the social sciences on using the focus group method can be subsumed under the following headings: subjects (target groups, composition of groups, recruitment), communication in the groups (discussion guide, moderator, moderating techniques), and analysis of focus groups (e.g., Morgan, 1993 ; Morgan & Krueger, 1998 ; Stewart et al., 2007 ). Specific requirements for health research can be identified in all three thematic fields: Recruitment might be facilitated by using registers of quality circles to recruit physicians or pharmacists, or by recruiting patients in outpatients departments. It might be hampered by heavy burdens on target groups—be they time burdens (e.g., clinical schedules, time-consuming therapy) or health constraints (e.g., physical fitness). With regard to communication in focus groups, finding suitable locations, identifying optimal group sizes, planning a good time line, as well as selecting suitable moderators (e.g., persons who are capable of translating medical terms into everyday language) might pose a challenge. The analysis of focus groups in health care research might also require special procedures because the focus group method is used to answer not only sociological research questions (e.g., related to the reconstruction of the perspectives of target groups) but also more specific research questions, such as user requirements with regard to written information or technical innovations.

The aim of our study was to gather more systematic methodological information for conducting focus groups in the context of health research in general and in the more specific context of the implementation of a technical innovation. To this end, we conducted interviews with focus group moderators about their experiences when planning and moderating focus groups. The groups in question were part of a research program aimed at developing and evaluating an electronic personal health record. We chose this program for several reasons: First, because it consisted of several subprojects devoted to different research topics related to the development of a personal electronic health record, it offered a variety of research content (cf. next section). Second, the focus groups were conducted to answer research questions of varying breadth, which can be regarded as typical of research in health care. Third, the focus groups comprised a variety of target groups—not only patients but also different types of health care professionals (general practitioners, independent specialists with different areas of specialization, hospital doctors, pharmacists, medical assistants, nursing staff).

In this article, we report the findings of these interviews in relation to the following questions: (a) What challenges associated with the characteristics of the target groups of health research (patients, physicians, other health care professionals) might be considered during the recruitment process? How should the specific research question relating to a technical innovation be taken into account during the recruitment process? (b) Should specific aspects of the communication styles of target groups be taken into account when planning and moderating focus groups in health care? Can additional challenges be identified in relation to the technical research question? and (c) How was the method appraised by the interviewees in their own research context?

Research Program and Description of Focus Groups

The “Information Technology for Patient-Centered Health Care” (INFOPAT) research program ( www.infopat.eu ) addresses the fact that, because patients with chronic conditions (e.g., colorectal cancer, type 2 diabetes) have complex health care needs, many personal health data are collected in different health care settings. The aim of the program is to develop and evaluate an electronic personal health record aimed at improving regional health care for chronically ill people and strengthening patients’ participation in their health care process. Subprojects are devoted, for example, to developing the personal electronic health record (Project Cluster 1), a medication platform (Project Cluster 2), and a case management system for chronically ill patients (Project Cluster 3). In the first, qualitative, phase, the researchers explored patients’ and health care professionals’ experiences with cross-sectoral health care and patient self-management, and their expectations regarding the advantages and disadvantages of a personal electronic health record. The information gathered in this phase of the program served as a basis for constructing a personal electronic health record prototype. This prototype was implemented as an intervention in a second, quantitative, phase dedicated to investigating the impact of such a record on a range of health care variables (e.g., self-management, health status, patient–doctor relationship, compliance). The University Hospital Heidelberg Ethics Committee approved the studies of the INFOPAT research program. All participants gave their written informed consent, and the participants’ anonymity and confidentiality were ensured throughout the studies according to the ethical standards of German Sociological Association. 1

Twenty-one focus groups were conducted during the qualitative phase of the program. Three groups consisted of colorectal cancer patients, four comprised type 2 diabetes patients, four were made up of physicians, three comprised physicians and pharmacists, four consisted of physicians and other health care professionals, and three consisted of other health care professionals (for more detailed information, see Tausch & Menold, 2015 ). Participants were recruited from urban and rural districts of the Rhine-Neckar region in Germany. Patients were approached in clinics, by their local general practitioners, or in self-help groups. Health care professionals were recruited in clinics, cooperating medical practices, and professional networks.

The focus groups took place at several locations at the National Center of Tumor Diseases (NCT) in Heidelberg, Germany, and the University of Heidelberg. The groups consisted of between four and seven participants and lasted between 1.5 and 2 hours. All focus groups were conducted by two researchers—a moderator and a co-moderator; a third researcher took notes. Semistructured discussion guides were used, and the groups were video- and audio recorded (cf., for example, Baudendistel et al., 2015 ; Kamradt et al., 2015 ). The researchers performed content analysis on the transcripts; the schema of categories was oriented toward the research questions. The focus groups addressed research questions of varying breadth, including, for example, individual health care experiences (comparatively broad), the expected impact of the record on the patient–doctor relationship (medium breadth), and technical requirements for such a personal health record (comparatively narrow). The variety of the research questions was important for our study because it proved to be of relevance for the interviewees’ appraisal of the usefulness of the focus group method.

Interviews With the Focus Group Moderators

We conducted qualitative interviews with nine of the 10 focus group moderators in the INFOPAT program (one moderator moved to a different department shortly after the completion of data collection and was not available for interview). The interviewees were aged between 30 and 54 years ( M age = 36 years; SD = 8.3 years). Their professions were health scientist, pharmacist, general practitioner, or medical ethicist. Their professional experience ranged from one to 23 years ( M = 7.1 years, SD = 7.7 years), and they had little or no previous experience of organizing and conducting focus groups. The moderators were interviewed in groups of one to three persons according to their project assignment (cf. Table 1 ).

Overview of Interviews and Interviewees.

The interviews lasted approximately 1 hour, and the interview questions were guided by the chronological order in which a focus group is organized and conducted (recruitment, preparation, moderation, methods) and by the utilization and usefulness of the results. We tape recorded the interviews, transcribed them verbatim, and performed qualitative content analysis on the transcripts ( Elo & Kyngäs, 2008 ; Mayring, 2015 ) with the help of the program MAXQDA 10.0.

The final system of categories 2 ( Tausch & Menold, 2015 ) consisted of two types of codes: All relevant text passages were coded with respect to the content of the statement. In addition, a second type of code was required if the statement related to a specific group of participants (e.g., patients, hospital doctors, men, women).

On the basis of the research questions, the contents of interview statements were classified into the three superordinate thematic categories: recruitment, communication in the focus groups, and appraisal of the focus group method. Consequently, the reporting of the results is structured according to three main topics.

Recruitment

Statements relating to the recruitment of the participants were sorted into the main categories “factors promoting participation”, “factors preventing participation”, and “general appraisal of the recruitment process”. Figure 1 shows the subcategories that were identified under these main categories. Because many of the statements referred only to patients or only to health care professionals (physicians, other health care professionals), the subcodes shown in Figure 1 are sorted by these two types of participants.

Factors relating to the recruitment process.

Factors relevant for all target groups

As the following interviewee statement shows, addressing potential participants face-to-face (rather than in writing) proved crucial for the success of recruitment in all target groups:

Well, a really good tip when recruiting patients is . . . to address the people yourself. Not to get someone else to do it who . . . has nothing to do with [the project], because ultimately you really do have to explain a lot of things, also directly to the patient. And then it’s always good if the person [who does the recruiting] is actually involved in the project. 3

In the case of the clinicians, being addressed by a superior was even more effective for their willingness to participate: “And then top down. If the nursing director asks me, then it’s not so easy to say no.”

Furthermore, a positive response was more often achieved if the groups were scheduled at convenient times for the addressees, and they only had to choose between several alternatives. Patients welcomed times contiguous with their therapies: “And many [of the patients] said: ‘Yes, maybe we can do it after my chemotherapy, on that day when I’m in the clinic anyway?’” Whereas medical assistants were given the opportunity to take part in the groups during working hours, general practitioners preferred evening appointments on less busy weekdays (e.g., Wednesdays and Fridays):

Well, what I found quite good was to suggest a day and a time. And we concentrated on the fact that practices are often closed on Wednesday afternoons. So that’s a relatively convenient day. And then evenings for the pharmacists from seven-thirty onwards.

Interest in the topic of the discussion, or at least in research in general, was an important variable for participation. Together with lack of time, it turned out to be the main reason why sampling plans could not be realized. Among patients, men were much more interested in discussing a technical innovation such as an electronic personal health record, while women—besides their lesser interest—often declined because of family responsibilities: “Well, I’d say a higher proportion of women said: ‘I have a lot to do at home, housework and with the children, therefore I can’t do it.’”

Family physicians, physicians from cooperating medical practices, and hospital doctors showed more interest in discussing an electronic personal health record than did medical specialists in private practice, who often saw no personal gain in such an innovation. For example, one interviewee stated,

Family physicians generally have a greater willingness [to engage with] this [health] record topic. They see . . . also a personal benefit for themselves. . . . or they simply think it might be of relevance to them or they are interested in the topic for other reasons. Some of them even approached us themselves and said, “Oh, that interests me and I’d like to take part.”

In addition, because of heavy workload, private practitioners were difficult to reach (e.g., by telephone). This also lowered the participation of this target group on the focus groups.

Factors relevant only for patients

Two other variables that influenced patients’ willingness to participate were mentioned in the interviews. First, because this target group consisted of cancer patients and diabetes patients with multimorbidity, poor physical fitness also prevented several addressees from participating in the groups. The inability to climb stairs, or the general inability to leave the house, made it impossible for them to reach the location where the groups took place: “[They] immediately replied: ‘Well, no, . . . that’s really too much for me,’ and unfortunately they could not, therefore, be included in the groups.” Furthermore, unstable physical fitness often led to high drop-out rates. The moderators of the focus groups therefore proposed that up to twice as many participants as required should be recruited: “And depending on the severity of the illness, you have to expect a drop-out rate of up to fifty percent. So, if you want to have four people, you should invite eight.”

Second, moderators reported that patients’ liking for, or dislike of, talking and discussing influenced their tendency to join the groups. Participating patients were generally described as talkative. For example: “And with patients, all in all, I had the feeling that those who agreed [to participate] were all people who liked talking, because those who did not like talking refused out of hand.” Patients who refused to participate often argued that they felt uncomfortable speaking in front of a group: “And the men, when they declined they often said: ‘No, group discussion is not for me! I don’t like talking in front of a group.’”

The researchers eventually succeeded in recruiting sufficient participants. However, they were not able to realize the sampling plans according to a certain proportion of male and female patients or types of physicians. “Well, we finally managed to fill up our groups, but only as many [participants] as necessary.” Comparing the different target groups, recruiting patients was described as easier than recruiting physicians: “And that was much easier insofar as you just had to go to the clinic and each day there were five or six patients whom you could address.” However, only 10% of the patients who were addressed agreed to participate. In the health care professional group, the recruitment rates ranged between 0% and 30%, depending on the subgroup. This can be demonstrated by the following interviewee utterance:

And in the private practitioner sector it was rather . . . . Well, we tried to recruit specialists in private practice, in other words internists, gastroenterologists, and oncologists. The success [rate proved to be] extremely poor. . . . Well, on the whole, the willingness to take part, the interest, is not there. Or, well they don’t give the reasons, but they say they don’t want to take part. So that was difficult and, yes, it didn’t go too well.

Communication in the Focus Groups

With regard to the communication in the focus groups, the moderators identified factors that influenced communication in a positive or negative way. In addition, we discussed a number of factors with them that are often described in the social science literature as problematic when conducting focus groups. However, the interviewees considered that some of these factors had not influenced communication in the focus groups conducted within the framework of the INFOPAT program. In our system of categories, we also coded whether the factors in question were related to (a) the setting or (b) the moderation of the focus groups (cf. Figure 2 ).

Influences on and characteristics of the focus group discussion.

Factors relating to the setting

As Figure 2 shows, communication was reported to be positively influenced by small group size, location, provision of food and beverages, and conducting the focus group without a break. In contrast to general recommendations on focus groups in the context of sociological research, the moderators in the INFOPAT program considered a smaller group size of between four and six participants to be ideal. With regard to location, the interviewees reported that, depending on the target group, different places were perceived as positive. Patients preferred locations inside the clinic because they were easy to reach and caused no additional effort. Furthermore, because these locations were familiar to them, they facilitated an atmosphere of security and ease, which was seen as an important prerequisite for an open and honest discussion. This is clear from the following quotation:

Well, the patient focus groups were all located at the clinic. We chose this location on purpose to make it easier for them, because they come to the clinic anyway for their therapy. And they know the place and they feel comfortable and in good hands.

By contrast, the clinician groups benefited from being located outside the clinic. In contrast to other common addressees of focus groups, these professionals were not only accustomed to participating in groups outside their familiar surroundings but also this location helped them to distance themselves from their professional duties and to engage more deeply in the discussion, as shown by the following quotation:

Yes, one was located at the O-Center. We chose this location on purpose so that the clinicians had to leave the hospital. It’s not too far, only a few yards away. But we wanted them to leave the clinic, and not to run back to the ward when they were called. And, well, I liked this location.

Food and beverages were welcome in all the groups and also helped to create a positive and trusting atmosphere. And finally, the interviewees found that it was better to omit the break, thereby avoiding the interruption of the ongoing discussion. This is reasonable considering the comparatively short duration of the focus group session (between 1.5 and 2 hours). Statements relating to a break might have been different in the case of longer focus group durations.

The interviewees reported that the size and temperature of the room and time pressure on the participants or the moderator had a negative impact on communication. Some of the focus groups in the project took place in midsummer and had to be held in rooms without blinds or air conditioning. The moderators of these groups had to work hard to maintain the participants’ (and their own) attention and concentration. Time pressure on the participants (e.g., the clinicians) led to an unwillingness to engage in active discussion and created a question-and-answer situation, as shown by the following statement:

And in one group of physicians . . . we never reached the point where they joined in fully. During the whole discussion they never completely arrived. And they had already cut the time short in advance. They were under so much time pressure that they were not able to discuss in an open manner.

Moderators reported that they, too, had experienced time pressure—namely, in situations where they did not have enough time to prepare the room and the recording devices. This had caused them to be nervous and stressed at the beginning of the discussion, which had negatively affected the mood of the participants, thereby rendering an honest and open discussion particularly difficult.

Factors relating to the moderation

Many of the positive factors reported by the interviewees have already been described for focus groups in general—for example, using open questions, directly addressing quiet participants, and handling the discussion guide in a flexible way. Furthermore, by showing interest in every statement, and by generating a feeling of security in every participant, moderators fostered a fruitful discussion:

I believe that another important point is that you are calm yourself. That you give the people the feeling “you can feel safe with me, you don’t have to worry that I will make fun of you . . . or that I won’t take you seriously.”

Interviewees also considered that building a bridge between the technical innovation under discussion (a web-based electronic personal health record) and everyday life (e.g., online banking) was an important factor in getting all participants to contribute to the discussion. As one interviewee noted,

We tried to anchor it in their everyday lives. And . . . the example that always worked was when we said: “Think of it as if it were a kind of online banking.” Everyone understands what online banking is. It’s about important data on the internet; they’re safe there somehow. I have my password. And people understood that. Well, it’s important to anchor it in their reality . . . because otherwise the topic is simply far too abstract.

In this context, the fact that the groups were moderated by the researchers themselves proved very helpful because they were able to answer all questions relating to the research topic. As the following quote shows, this was an important prerequisite for opinion formation on the part of participants:

Well, I think that a really important quality criterion . . . is that you have completely penetrated [the topic]. If you only know the process from the outside . . . and you then conduct the focus group about it. . . . Somewhere, at some stage, [one discussion] narrowly missed the point. . . . You simply have to be totally immersed in the topic, well, I believe that [someone who is totally immersed in the topic] is the ideal person for the job. And in our case the thinking was, okay, so I’m a doctor, but on balance it’s more important that both [moderators] are absolutely well informed because it’s a complex topic.

The more specific the research question was, the more useful the moderating strategy of inviting one participant after the other to express their opinion appeared to be. By using this strategy, the moderators ensured that every participant contributed to the discussion.

A point that was strongly emphasized by the interviewees was the duration of the round of introductions at the beginning of the focus group session. In the patient groups, introductions took much more time than the researchers had expected. Patients had a high need to express themselves and to tell the others about their illness and their experiences with the health system. Although this left less time to work through the topics in the discussion guide, the researchers came to realize that there were several good reasons not to limit these contributions: First, the introductions round proved important for helping the participants to “arrive” at the focus group, for creating a basis of trust, and for building up a sense of community among the participants. Second, the interviewees reported that, because many topics in the discussion guide (e.g., participants’ experiences with coordinating visits to different medical specialists) had already been brought up in the round of introductions, they did not have to be discussed further at a later stage:

And that is the crux of this general exchange of experiences at the beginning. Sure, it costs you a lot of time, but I almost think that if you don’t give them that time, you won’t get what you want from them, in the sense that you say: “I want to hear your frank opinion or attitude.” You don’t want them to simply answer you because they think that’s what you want to hear. You have to create an atmosphere in which they really forget where they are. I’m relatively convinced that you wouldn’t achieve that without such [a round of introductions].

The moderators’ experience in the physician groups was different. These groups benefited from having a rather short round of introductions. Giving participants too much time to introduce themselves meant that they presented their expertise rather than reporting their experiences. In contrast to the patient groups, this did not substantially contribute to the discussion of the research topics.

Depending on the context, status differences between the moderators and the participants, or among the participants, were appraised differently by interviewees. In one group comprising physicians and medical assistants, the moderators observed that status differences had a negative influence on communication. Very young female medical assistants, in particular, did not feel free to express their opinions in the presence of their superiors. By contrast, presumed differences in status between family doctors, hospital doctors, and medical specialists in private practice did not have any negative impact on communication. Nor did different forms of address (some participants in these groups were addressed by their first name and some by their last name, depending on the relationship between the moderator and the participants). Status differences between moderators (if medical doctors) and participants (patients) had an impact on communication when patients regarded doctors as an important source of information (e.g., about the meaning of their blood values) or as representatives of the health care system to whom complaints about the system should be addressed. The latter case was the subject of the following interview statement by a moderator who is a physician by profession:

And a lot [was said about] the kind of experiences they had had here at the NCT. And of course, when the patients have been treated here for many years—or even for not so many [years], but they have had many experiences—they sometimes reported at length. And I had the feeling that this had a bit of a feedback function, quite generally, for the NCT. Also the somehow frustrating experiences they had had, or a lot of things that had not gone that well in conversational exchanges [with the staff]. There was a relatively large amount of feedback that didn’t have a lot to do with the topic because I was, of course, involved as a senior physician and I am not an external researcher, but rather someone who is also seen as being jointly responsible, or at least as someone who can channel criticism.

Finally, because most of the moderators were not medical professionals, they did not experience the translation of medical or technical terms into everyday language as problematic. Rather, they automatically used terms that were also familiar to the participants.

Characteristics of the discussion

The factors described above resulted in focus group discussions that might be interpreted as characteristic of health research. The patient focus groups were characterized by a strong need to talk and a high need for information. In the health care professional focus groups, researchers experienced a greater variety of communication styles. Because of a lack of time, or because they falsely expected a question-and-answer situation, some groups demonstrated a low degree of willingness to engage in discussion:

Although, I believe that was partly due . . . well there was one [woman] who was very demanding; she wanted to know straight away: “Yes, what’s the issue here? What do I have to say to you?” Well, the three who came from the one practice, I think they really had the feeling that we would ask them questions and they would bravely answer them and then they could go home again. So, for them this principle that they were supposed to engage in a discussion, for them that was somehow a bit, I don’t know . . . disconcerting. . . . They really thought: “Okay, well we want to know now what this is all about. And they’ll ask us the questions and then we’ll say yes, no, don’t know, maybe. And then we’ll go home again.” Well, at least that was my impression.

Other groups, especially those consisting of different types of health care professionals (e.g., physicians with different areas of specialization, or physicians and pharmacists), were characterized by lively discussion and a great variety of opinions.

Appraisal of the Focus Group Method

We classified moderators’ statements relating to the appraisal of the focus group method into four main categories: “advantages of the method”, “disadvantages of the method”, “recommendations for other researchers in related research areas”, and “statements on how they used the results” (cf. Figure 3 ).

Appraisal of the focus group method.

The researchers reported that the focus group method yielded a rich blend of perspectives and opinions, brought forth, in particular, by the interaction between the participants:

But for this question and the topic, and for our lack of knowledge, that was . . . a lot of new information . . . and very many good ideas and critical remarks that you naturally read in the literature from time to time. But, let’s say, because of the complexity of the participants’ reactions and the weight they attached to things, it’s different than reading in a literature review that [this or that] could be taken into account.

The results of the focus groups further enriched the researchers’ work by relating it to everyday life: “Well, what was nice was that the topic was related to the participants’ lives. That people said: ‘Now the topic is important for me.’” Furthermore, the method yielded information about which aspects were most important and how the variety of opinions should be prioritized. This was achieved, in particular, by using participant-generated cards:

And with regard to prioritization, we incorporated it using participant-generated cards. We said: “Look: If you could develop this record now, what would be the three most important things that must absolutely be taken into consideration, from your point of view, no matter what they relate to.” And they wrote them down on the cards. And after that they were asked to carry out their own prioritization—that is, what was most important to them personally. One person wrote “data protection” first, while another [wrote] “sharing with my wife.” . . . That was good. . . . That helped a lot because it was simply clear once again what things were important to them.

In cases where concrete questions had to be answered or decisions had to be made, the interviewees also welcomed the opportunity to use structuring methods such as presentations, flip-charts, and participant-generated cards to obtain the relevant information:

. . . Well, the aim was that at the end we [would] have a set of requirements for the engineering [people]. And the engineering [people] don’t so much want to know about experiences and desires and barriers, but rather they want to know should the button be green or red and can you click on it. And that’s why I thought at the beginning it will be difficult with a focus group and an open discussion. Now, if you say that one can also interpret a focus group the way we did, partly with very specific questions and these participant-generated cards, then I think it is indeed possible to answer such questions as well.

Disadvantages

The main disadvantages of the focus group method were seen in the considerable organizational effort and expenditure of time involved. A question raised by some of the interviewees was whether comparable results could have been achieved using less time-consuming and organizationally demanding methods.

It’s true to say that you lose time. Well, you could implement [the innovation] straight away and see whether it’s better. Maybe, in this case you’re wrong and you just think it’s better or in any case not worse than before. You basically lose a year on this whole focus groups thing.

Moreover, in some cases, the discussion went in an unwanted direction and the moderators never fully succeeded in bringing the group back to the intended topics.

Furthermore, like many other medical research projects, INFOPAT included quite specific research questions. In this connection, the moderators emphasized that open focus group discussions would not have succeeded in answering those questions. Only by using methods such as participant-generated cards and prioritization was it possible to answer at least some of them. Nonetheless, some interviewees did not consider the focus group method to be really suitable for this type of research questions:

Of course we also have our engineers as counterparts who . . . need very specific requirements at some point. The question is whether such a focus group . . . . [It] can’t answer that in detail in this first stage. It’s simply not practicable.

Recommendations

As described under the “Communication in the Focus Groups” section above, the round of introductions in the patient groups lasted much longer than planned, thereby shortening the time available for other topics in the discussion guide. As a result, the moderators decided to choose a different thematic focus in each group so that every topic was discussed more deeply in at least one group.

What we usually did was to consider what hadn’t been addressed that much in the previous focus group. That [topic] was given more room in the next focus group because the guide, well it was quite a lot. You could have easily gone on discussing for another hour or two.

Using the results

On the whole, the researchers were satisfied with the number of groups that were conducted and the results that they yielded. They did not agree that more groups would have led to better, or different, results—with one possible exception, namely, in the case of specific target groups (e.g., migrants). Only one group had been composed of patients with a migrant background, and, as one interviewee stated, “I just thought, the patients with a migrant background . . . now that was [only] one group, it by no means covers the whole range.”

In cases where the results of the focus groups were perceived as not being concrete enough to proceed to the next research step (e.g., formulating a specification sheet for the construction of the electronic personal health record), the researchers planned to bring experts together in a roundtable format to make decisions on the basis of the priorities, agreements, and disagreements that had emerged from the focus groups. Following the construction of a prototype, they intended to conduct further focus groups to validate or adapt the usability of the electronic personal health record system.

Our analysis of interviews with focus group moderators yielded considerable insights into methodological aspects of conducting focus groups in health research. Our first research question related to characteristics of the target groups that should be considered during the recruitment process. We identified face-to-face contact as an important factor promoting focus group participation. The interviewees considered this type of contact to be better suited to answering target persons’ questions and explaining the method and aims of the focus groups. Moreover, they felt that addressees might find it more difficult to decline a face-to-face invitation than a written one. With regard to health care professionals, an invitation issued by a hierarchically higher person was most effective, even though ethical aspects should be considered in this case, and voluntary participation should nevertheless be ensured. Otherwise, the order to participate might prevent an atmosphere of open communication and might lead to a lower quantity or to more negative statements.

Furthermore, whereas physicians are usually accustomed to discussing topics with others, an important characteristic that influenced willingness to participate on the part of members of other target groups (other health care professionals, patients) was a liking for, or a dislike of, talking. Researchers might take account of this fact by explaining the method in more detail, by developing arguments to overcome fears, or, as suggested, for example, by Colucci (2007) , by convincing the addressees with other activities implemented in the focus groups. Other relevant personal characteristics—be they related to the research topic (e.g., technical interest in the case of an electronic innovation) or to the specific target group (e.g., physical fitness on the part of patients or lack of time on the part of health care professionals)—should be anticipated when planning recruitment. These characteristics might be taken into account by preparing arguments, providing incentives, giving thought to favorable dates and times, and choosing easily accessible locations. An interesting finding was that, depending on the target group, different locations were considered to have a positive influence on the discussion. Whereas locations inside the clinic were preferred in the case of the patient focus groups because of familiarity and easy accessibility, hospital doctors were more engaged in the discussion when the focus group site was located at least some yards away from their workplace.

Finally, the experience of our researchers that up to 50% of the patients had to cancel at short notice because of health problems does not appear to be uncommon in this research context. That overrecruitment is an effective strategy—particularly in health care research—has been reported by other authors (e.g., Coenen et al., 2012 ).

With our second research question, we focused on aspects of communication in the focus groups. The interviews revealed several factors specific to research topics and addressees of health care studies that influenced the discussions. Consequently, in addition to considering general recommendations regarding the organization and moderation of focus groups (e.g., choosing adequate rooms with a pleasant atmosphere, serving food and beverages, using open questions, showing interest in all contributions, and directly addressing quiet participants), these health care specific aspects should be taken into account. Relevant factors that should be addressed when moderating focus groups in this context are (a) the strong need to talk and the high need for information in the patient groups, (b) status differences between the participants or between the moderators and the participants, (c) the size of the focus group, and (d) the specificity of the topic of discussion. The interview data revealed that these factors influenced the discussions and thus the results achieved with the groups. In addition, the following four possibilities of addressing these factors were identified:

First, the moderators had to devote more time to the round of introductions in the patient groups, which served as a warm-up, created an atmosphere of fellowship and openness, and accommodated this target group’s strong need to talk. Second, with respect to status differences between the moderator and the participants, no definite recommendations can be derived from the interviews. The interviewees found that it was less favorable when the moderator was perceived not only in that role but also in other roles (e.g., physician), because this might hamper a goal-oriented discussion. However, they considered deep insight into the research topic on the part of the moderators to be beneficial, at least for certain research topics. Thus, one should carefully weigh up whether it is more advantageous or more disadvantageous when the group moderator is a physician. Interviewees considered status differences between participants to be disadvantageous only in one case, where—because of organizational constraints—medical assistants and their superiors joined the same focus group, which gave rise to some reticence on the part of the young assistants. Similar problems have been reported by other authors, for example, Côté-Arsenault and Morrison-Beedy (2005 ; see also Hollander, 2004 ). However, interviewees did not experience as problematic status differences between physicians with different areas of specialization.

Third, with respect to group size, interviewees found comparatively small focus groups appropriate to give all participants enough time to tell their stories. In contrast to social science research, where groups of between eight and 20 participants are recommended, our interviewees considered groups of between four and six persons to be optimal. This is in line with Côté-Arsenault and Morrison-Beedy (2005) , who recommended small groups for health research, especially when sensitive topics are discussed. Our interview data revealed that this recommendation might also be useful for other health research topics.

Fourth, with regard to the topic of the discussion, interviewees found it helpful to structure different phases of the discussion in different ways, depending on the specificity of the research questions. In contrast to social science research, certain types of research questions in health research require comparatively specific answers. Some of the focus groups in our study were aimed at collecting participants’ expectations regarding an electronic personal health record or—even more specifically—at developing a product specifications document. Conducting focus groups during the development of a technical innovation is a method that is being increasingly used in health care research. Hence, the experiences of the interviewees with regard to these aspects of their research might be relevant for many other research programs. For this type of research questions, it proved useful to include more structured parts in the discussion, for example, having certain questions answered by each participant in turn, or using methods such as participant-generated cards and prioritization. This made it easier to obtain the opinion of each participant and to cover as many concerns and expectations as possible. This finding is in line with recommendations by Colucci (2007) , who proposed the use of activity-oriented questions for health research topics as an enrichment of data collection and a means of making it easier to talk about sensitive and complex topics.

All the moderators found that their discussion guides contained too many questions and too many topics. This might have been due, at least partly, to a desire to determine all relevant aspects in advance—a tendency that might be typical of health research. However, Morgan (1995) also addressed this phenomenon in relation to social research in general: “A common error in focus group question guidelines is too much emphasis on what is of interest to the researcher and not enough emphasis on what is of interest to the participants” (p. 520).

With our third research question, we addressed the appraisal of the focus group method in the interviewees’ research context. Our results show that one should think carefully before using focus groups in the field of health research. The impression that they are quick and easy to conduct might be a misconception, especially in this research context. In fact, the appraisal of the method by the moderators revealed both advantages and disadvantages. The main advantages were the rich blend of perspectives and opinions obtained and the opportunity to have them prioritized by the target groups. For their research topics, the interviewees saw a further important advantage in the fact that they were able to relate their scientific research to everyday life, a point that might be of general importance for a number of research questions in health research, especially those that refer to new medical diagnostics or technical innovations.

The interviewees considered that the main disadvantages of focus groups were the substantial organizational effort and expenditure of time they required. They raised the question whether comparable results could have been achieved using less costly methods. Fortunately, we conducted our interviews with researchers from a research program aimed at answering research questions of different degrees of specificity. As a result, the moderators were able to compare the usefulness of focus groups for different types of research questions. Their statements revealed that they were satisfied with the results relating to more open research questions such as experiences with cross-sectoral health care. For more specific research questions, the interviewees valued the possibility of organizing the discussions in a more structured way and using methods that activated all participants (e.g., participant-generated cards, prioritizations). Nonetheless, they considered meetings of experts to be a necessary intermediate step, for example, on the way to a product specifications document. We recommend that, depending on the specificity of the results that are projected, consideration should be given to including such intermediate steps in the planning stage.

Limitations of the Study

Our analysis of the interviews with the focus group moderators revealed a number of methodological problems that typically occur when focus groups are used in a health research context and yielded recommendations on using such groups in this context. However, some limitations of the present study should also be discussed: First, we conducted our research with focus group moderators, all of whom worked in the same research program. Even though the INFOPAT program consists of several subprojects, they all deal to a greater or lesser extent with the advantages and disadvantages of an electronic support system (electronic personal health record). Furthermore, the moderators were mainly health scientists and had little or no experience with conducting focus groups. This might also have been specific for the research program in which our study was conducted. In other health care programs, focus groups might be moderated mainly by physicists or lay persons (e.g., in participatory health research). Consequently, had we also conducted interviews with focus group moderators from other research areas or included moderators with other professions or more focus group experience, this might have led to different results. However, our research project is rather typical for applied qualitative research in medical science when developing new technologies. Here, focus groups are used by the researchers to find out the potential requirements for the new technology. The researchers are often experts in a specific scientific topic and have no or only limited experience in conducting qualitative research in terms of focus groups. Therefore, our findings are of a particular importance for the researchers with little experiences in conducting focus groups, which can apply to every research, conducted first time. In addition, the little experience of our focus group moderators was a special advantage and strength of the study. More experienced moderators would have prevented some of the problems our moderators—as other unexperienced moderators—faced. As a result, the moderators would not have named these potential problems in the interviews and given no advice for preventing them.

Second, the study was conducted in Germany and thus represents problems and challenges of the German health care system. In other countries, physicians might have different work-shifts or there might be different possibilities in the health care system to reach the target groups. Therefore, more research on the methodology of focus groups in the context of the development of new technologies in health care in other countries and cultures with a consideration of additional relevant groups is needed.

Third, in our interviews, we focused mainly on the organization and conducting of focus groups. For two reasons, we did not address the aspect of data analysis: First, we conducted the interviews shortly after the focus groups had been completed, at a time when data analysis was still in progress. Second, analysis of qualitative data can be carried out in many different ways, depending on research questions and preferences of researchers, and some of the recommended methods are very complex. Had we discussed them in detail, it would have been too time-consuming in the interviews.

Concluding Remarks

Our results revealed a number of methodological challenges that might be typical of conducting focus groups in health research. We hope that our findings will be of use to researchers in similar research fields. Furthermore, we encourage other researchers who are interested in health research topics to gather more information about methodological aspects specific to this research field. Our results were achieved in the context of the development of a technical innovation. It might be interesting to endeavor to replicate them in other health care research projects dealing with technical innovations. Moreover, we would encourage researchers of other topics in health research to interview focus group moderators about their experiences in their specific research context. We hope that our results will serve as a useful basis for comparing results in different areas of health research.

Table of contents

What is a focus group, step 1: choose your topic of interest, step 2: define your research scope and hypotheses, step 3: determine your focus group questions, step 4: select a moderator or co-moderator, step 5: recruit your participants, step 6: set up your focus group, step 7: host your focus group, step 8: analyse your data and report your results, advantages and disadvantages of focus groups, frequently asked questions about focus groups.

Focus groups are a type of qualitative research . Observations of the group’s dynamic, their answers to focus group questions, and even their body language can guide future research on consumer decisions, products and services, or controversial topics.

Focus groups are often used in marketing, library science, social science, and user research disciplines. They can provide more nuanced and natural feedback than individual interviews and are easier to organise than experiments or large-scale surveys .

Prevent plagiarism, run a free check.

Focus groups are primarily considered a confirmatory research technique . In other words, their discussion-heavy setting is most useful for confirming or refuting preexisting beliefs. For this reason, they are great for conducting explanatory research , where you explore why something occurs when limited information is available.

A focus group may be a good choice for you if:

• You’re interested in real-time, unfiltered responses on a given topic or in the dynamics of a discussion between participants
• Your questions are rooted in feelings or perceptions , and cannot easily be answered with ‘yes’ or ‘no’
• You’re confident that a relatively small number of responses will answer your question
• You’re seeking directional information that will help you uncover new questions or future research ideas
• Structured interviews : The questions are predetermined in both topic and order.
• Semi-structured interviews : A few questions are predetermined, but other questions aren’t planned.
• Unstructured interviews : None of the questions are predetermined.

Differences between types of interviews

Make sure to choose the type of interview that suits your research best. This table shows the most important differences between the four types.

Topics favorable to focus groups

As a rule of thumb, research topics related to thoughts, beliefs, and feelings work well in focus groups. If you are seeking direction, explanation, or in-depth dialogue, a focus group could be a good fit.

However, if your questions are dichotomous or if you need to reach a large audience quickly, a survey may be a better option. If your question hinges upon behaviour but you are worried about influencing responses, consider an observational study .

• If you want to determine whether the student body would regularly consume vegan food, a survey would be a great way to gauge student preferences.

However, food is much more than just consumption and nourishment and can have emotional, cultural, and other implications on individuals.

• If you’re interested in something less concrete, such as students’ perceptions of vegan food or the interplay between their choices at the dining hall and their feelings of homesickness or loneliness, perhaps a focus group would be best.

Once you have determined that a focus group is the right choice for your topic, you can start thinking about what you expect the group discussion to yield.

Perhaps literature already exists on your subject or a sufficiently similar topic that you can use as a starting point. If the topic isn’t well studied, use your instincts to determine what you think is most worthy of study.

Setting your scope will help you formulate intriguing hypotheses , set clear questions, and recruit the right participants.

• Are you interested in a particular sector of the population, such as vegans or non-vegans?
• Are you interested in including vegetarians in your analysis?
• Perhaps not all students eat at the dining hall. Will your study exclude those who don’t?
• Are you only interested in students who have strong opinions on the subject?

A benefit of focus groups is that your hypotheses can be open-ended. You can be open to a wide variety of opinions, which can lead to unexpected conclusions.

The questions that you ask your focus group are crucially important to your analysis. Take your time formulating them, paying special attention to phrasing. Be careful to avoid leading questions , which can affect your responses.

Overall, your focus group questions should be:

• Open-ended and flexible
• Impossible to answer with ‘yes’ or ‘no’ (questions that start with ‘why’ or ‘how’ are often best)
• Unambiguous, getting straight to the point while still stimulating discussion
• Unbiased and neutral

If you are discussing a controversial topic, be careful that your questions do not cause social desirability bias . Here, your respondents may lie about their true beliefs to mask any socially unacceptable or unpopular opinions. This and other demand characteristics can hurt your analysis and bias your results.

• Engagement questions make your participants feel comfortable and at ease: ‘What is your favourite food at the dining hall?’
• Exploration questions drill down to the focus of your analysis: ‘What pros and cons of offering vegan options do you see?’
• Exit questions pick up on anything you may have previously missed in your discussion: ‘Is there anything you’d like to mention about vegan options in the dining hall that we haven’t discussed?’

It is important to have more than one moderator in the room. If you would like to take the lead asking questions, select a co-moderator who can coordinate the technology, take notes, and observe the behaviour of the participants.

If your hypotheses have behavioural aspects, consider asking someone else to be lead moderator so that you are free to take a more observational role.

Depending on your topic, there are a few types of moderator roles that you can choose from.

• The most common is the dual-moderator , introduced above.
• Another common option is the dueling-moderator style . Here, you and your co-moderator take opposing sides on an issue to allow participants to see different perspectives and respond accordingly.

Depending on your research topic, there are a few sampling methods you can choose from to help you recruit and select participants.

• Voluntary response sampling , such as posting a flyer on campus and finding participants based on responses
• Convenience sampling of those who are most readily accessible to you, such as fellow students at your university
• Stratified sampling of a particular age, race, ethnicity, gender identity, or other characteristic of interest to you
• Judgement sampling of a specific set of participants that you already know you want to include

Beware of sampling bias , which can occur when some members of the population are more likely to be included than others.

Number of participants

In most cases, one focus group will not be sufficient to answer your research question. It is likely that you will need to schedule three to four groups. A good rule of thumb is to stop when you’ve reached a saturation point (i.e., when you aren’t receiving new responses to your questions).

Most focus groups have 6–10 participants. It’s a good idea to over-recruit just in case someone doesn’t show up. As a rule of thumb, you shouldn’t have fewer than 6 or more than 12 participants, in order to get the most reliable results.

Lastly, it’s preferable for your participants not to know you or each other, as this can bias your results.

A focus group is not just a group of people coming together to discuss their opinions. While well-run focus groups have an enjoyable and relaxed atmosphere, they are backed up by rigorous methods to provide robust observations.

Confirm a time and date

Be sure to confirm a time and date with your participants well in advance. Focus groups usually meet for 45–90 minutes, but some can last longer. However, beware of the possibility of wandering attention spans. If you really think your session needs to last longer than 90 minutes, schedule a few breaks.

Confirm whether it will take place in person or online

You will also need to decide whether the group will meet in person or online. If you are hosting it in person, be sure to pick an appropriate location.

• An uncomfortable or awkward location may affect the mood or level of participation of your group members.
• Online sessions are convenient, as participants can join from home, but they can also lessen the connection between participants.

As a general rule, make sure you are in a noise-free environment that minimises distractions and interruptions to your participants.

Consent and ethical considerations

It’s important to take into account ethical considerations and informed consent when conducting your research. Informed consent means that participants possess all the information they need to decide whether they want to participate in the research before it starts. This includes information about benefits, risks, funding, and institutional approval.

Participants should also sign a release form that states that they are comfortable with being audio- or video-recorded. While verbal consent may be sufficient, it is best to ask participants to sign a form.

A disadvantage of focus groups is that they are too small to provide true anonymity to participants. Make sure that your participants know this prior to participating.

There are a few things you can do to commit to keeping information private. You can secure confidentiality by removing all identifying information from your report or offer to pseudonymise the data later. Data pseudonymisation entails replacing any identifying information about participants with pseudonymous or false identifiers.

Preparation prior to participation

If there is something you would like participants to read, study, or prepare beforehand, be sure to let them know well in advance. It’s also a good idea to call them the day before to ensure they will still be participating.

Consider conducting a tech check prior to the arrival of your participants, and note any environmental or external factors that could affect the mood of the group that day. Be sure that you are organised and ready, as a stressful atmosphere can be distracting and counterproductive.

Starting the focus group

Welcome individuals to the focus group by introducing the topic, yourself, and your co-moderator, and go over any ground rules or suggestions for a successful discussion. It’s important to make your participants feel at ease and forthcoming with their responses.

Consider starting out with an icebreaker, which will allow participants to relax and settle into the space a bit. Your icebreaker can be related to your study topic or not; it’s just an exercise to get participants talking.

Leading the discussion

Once you start asking your questions, try to keep response times equal between participants. Take note of the most and least talkative members of the group, as well as any participants with particularly strong or dominant personalities.

You can ask less talkative members questions directly to encourage them to participate or ask participants questions by name to even the playing field. Feel free to ask participants to elaborate on their answers or to give an example.

As a moderator, strive to remain neutral. Refrain from reacting to responses, and be aware of your body language (e.g., nodding, raising eyebrows). Active listening skills, such as parroting back answers or asking for clarification, are good methods to encourage participation and signal that you’re listening.

Many focus groups offer a monetary incentive for participants. Depending on your research budget, this is a nice way to show appreciation for their time and commitment. To keep everyone feeling fresh, consider offering snacks or drinks as well.

After concluding your focus group, you and your co-moderator should debrief, recording initial impressions of the discussion as well as any highlights, issues, or immediate conclusions you’ve drawn.

The next step is to transcribe and clean your data . Assign each participant a number or pseudonym for organisational purposes. Transcribe the recordings and conduct content analysis to look for themes or categories of responses. The categories you choose can then form the basis for reporting your results.

Just like other research methods, focus groups come with advantages and disadvantages.

• They are fairly straightforward to organise and results have strong face validity .
• They are usually inexpensive, even if you compensate participant.
• A focus group is much less time-consuming than a survey or experiment , and you get immediate results.
• Focus group results are often more comprehensible and intuitive than raw data.

Disadvantages

• It can be difficult to assemble a truly representative sample. Focus groups are generally not considered externally valid due to their small sample sizes.
• Due to the small sample size, you cannot ensure the anonymity of respondents, which may influence their desire to speak freely.
• Depth of analysis can be a concern, as it can be challenging to get honest opinions on controversial topics.
• There is a lot of room for error in the data analysis and high potential for observer dependency in drawing conclusions. You have to be careful not to cherry-pick responses to fit a prior conclusion.

A focus group is a research method that brings together a small group of people to answer questions in a moderated setting. The group is chosen due to predefined demographic traits, and the questions are designed to shed light on a topic of interest. It is one of four types of interviews .

As a rule of thumb, questions related to thoughts, beliefs, and feelings work well in focus groups . Take your time formulating strong questions, paying special attention to phrasing. Be careful to avoid leading questions , which can bias your responses.

The four most common types of interviews are:

• Focus group interviews : The questions are presented to a group instead of one individual.

Social desirability bias is the tendency for interview participants to give responses that will be viewed favourably by the interviewer or other participants. It occurs in all types of interviews and surveys , but is most common in semi-structured interviews , unstructured interviews , and focus groups .

Social desirability bias can be mitigated by ensuring participants feel at ease and comfortable sharing their views. Make sure to pay attention to your own body language and any physical or verbal cues, such as nodding or widening your eyes.

This type of bias in research can also occur in observations if the participants know they’re being observed. They might alter their behaviour accordingly.

Jean Kaluza

Qualitative research is a fact-finding method for exploring and understanding people's beliefs, attitudes, experiences, and behaviors.

It involves collecting and analyzing data for insights into complex phenomena and social issues.

Researchers take this detailed data and analyze it using techniques such as content analysis, thematic analysis, or grounded theory to identify patterns and themes in the data.

Qualitative research can inform policies, design interventions, or improve services. 

Analyze focus group sessions

• What is a focus group?

A focus group is a qualitative fact-finding method involving a small group of five to 10 people discussing a specific topic or issue. A moderator leads the group, poses open-ended questions, and encourages participant discussion and interaction.

A focus group aims to gain insights into participants' opinions, attitudes, beliefs, and behaviors about the discussed topic. 

Marketing research, product development, and social sciences use focus groups to understand consumer behavior, attitudes, and preferences. They can also explore social issues, gather feedback on new ideas, or evaluate the effectiveness of a program or intervention.

You can conduct in-person or online focus groups and record and transcribe the sessions for analysis. You use thematic or content analysis to analyze the data and identify patterns in the participants' responses.

• Why do researchers use focus groups?

Researchers use focus groups for various reasons, primarily to gain qualitative insights and opinions from people with similar characteristics. 

Here are other reasons for focus groups:

Understand consumer behavior

Focus groups are ideal in marketing research for gathering insights into consumer preferences and behavior. Researchers can better understand what motivates their target audience, needs, wants, and what drives their purchasing decisions.

Gather feedback on new ideas

Focus groups can gather feedback on new products, services, or ideas. Researchers can present a new concept to a focus group and ask for their opinions to see how well they receive the idea. They can also learn what changes might be necessary and the potential market.

Evaluate the effectiveness of programs or interventions

Focus groups can help evaluate the effectiveness of a program or intervention. Researchers can ask participants to share their experiences and opinions to gain insights into their experience with the program. They can determine what aspects of the program work well, what could be improved, and its impact on participants.

Explore social issues

Focus groups can help explore social issues, such as attitudes toward a particular topic or the impact of a social program. Bringing together a diverse group of people can help researchers gain a more nuanced understanding of the issue and identify potential solutions or interventions.

Focus groups are a helpful tool for gaining qualitative insights and opinions from people with shared attributes. You can use these groups in different settings, and they’re handy for exploring complex issues that require in-depth understanding.

When should you use a focus group?

Here are some situations where a focus group might be appropriate:

If you’re launching a new product or service and want to gather feedback on your concept, features, and branding

To better understand your target audience's behavior, attitudes, and partiality by helping you identify patterns and trends in their decision-making

When you want to evaluate the effectiveness of a program or intervention by understanding the participant's experiences and opinions

If you want to develop effective marketing strategies with insights into what resonates with your target audience

When you want to explore social issues, such as the impact of a social program, and gain a deeper understanding of the issue at hand

Focus groups are less useful for situations where you need quantitative data or a representative sample of the broader population. It's essential to carefully plan your focus group, including selecting willing participants, choosing a moderator, and developing a discussion guide to achieve your research goals.

• 7 examples of focus groups

Researchers can use focus groups in different settings to gather feedback and opinions on products, services, or topics. Here are some examples of focus groups:

1. Product testing

Marketers can use a focus group to test a new product. For example, a company plans to launch a new line of skincare products and wants to get feedback from potential customers before the launch. The company organizes focus groups with participants who match their target market demographic and supplies a moderator with a discussion guide.

The moderator asks the focus group participants to try the products and provide feedback on the product's packaging, scent, texture, effectiveness, and overall appeal. 

They question participants about their current skincare routine, what products they use, and what they look for in skincare products.

The company changes the product packaging, ingredients, and pricing based on feedback. This ensures the product meets the needs and preferences of the target market. 

Now, the company can launch the new skincare line with confidence that its target market will love the product.

2. Advertising campaigns

Focus groups can test the success of advertising campaigns. Participants provide feedback on the ad's messaging, visuals, and tone, helping a company refine the campaign before launch.

For example, a brand organizes a focus group with participants who match their target demographic before launching their new advertising campaign.

If the focus group participants find the ad's message too complicated or unclear, the company can simplify the message based on feedback. This makes the ad more attractive and digestible for its target audience.

3. Political campaigns

Political participants can use focus groups to gather information about: 

What issues are most important to voters

How voters feel about the candidate and their message

How the candidate can improve their message and campaign strategy

For example, a political campaign might convene a focus group of voters from a particular demographic, such as suburban women or young adults. 

The leader might ask the focus group questions about their feelings and attitudes towards the candidate, the issues they care about most, and how they perceive the candidate's stance.

4. Market research

Marketers can use focus groups to gather information about consumers' likes and dislikes about a particular product or service. They can use this information to guide product development, marketing, and advertising strategies.

For example, a company forms a focus group to gather feedback on a new product concept, such as a new type of food packaging. 

The moderator asks the focus group questions about their perceptions of the product, the likelihood of purchasing it, and any suggestions they have for improving it. 

5. Product development

Focus groups can gather qualitative data from potential users or customers to understand their needs, preferences, and experiences with the product.

Companies can use focus groups at different stages, from the initial concept development to the testing and refinement of prototypes. 

For example, a business gathers a focus group to provide feedback on a new music streaming service app, and participants answer questions about: 

Their experiences with their current music streaming experiences

Preferences for layout

Impressions of the new streaming service

Product development teams can use this feedback to ensure the product meets the needs and expectations of the target market.

6. Healthcare

Healthcare focus groups can gather feedback and insights from patients, healthcare providers, and other stakeholders. 

Healthcare providers can use focus groups to gather qualitative data on various topics, including patient experiences, healthcare delivery, policies, and products.

For example, a provider uses a focus group to gather feedback on a new healthcare policy related to access to care. Participants answer questions about their experiences accessing healthcare, opinions on the policy, and any suggestions for improvements.

7. Education

Educators can use focus groups to get insights into student experiences and preferences to improve the quality of education and student engagement. 

Focus groups can also collect feedback from teachers and parents on issues such as teaching methods, parental involvement, and student performance.

Decision-makers can use this feedback to improve curriculum development, teaching methods, school policies, and educational products to meet the needs of students and educators.

• The pros and cons of focus groups

Focus groups are a popular research method to gather feedback and opinions from small, diverse groups. While focus groups can provide valuable insights, they also have drawbacks.

Provides in-depth insights

Focus groups allow in-depth discussions and more comprehensive insights into a topic. Participants can provide detailed feedback and share their opinions, attitudes, and experiences.

Encourages group dynamics

Focus groups encourage participants to interact and discuss the topic with each other, generating new ideas and insights. Participants can build on each other's thoughts and ideas, leading to a more extensive and nuanced discussion.

Cost-effective

Conducting a focus group can be less expensive than other research methods, such as one-on-one interviews or surveys . It can be more cost-effective to gather a group in one location rather than travel to different locations to conduct individual interviews.

Can be used to test ideas

Focus groups can test new ideas, products, or services before they launch. It allows companies to gather feedback from potential customers, enabling more informed decisions.

Flexibility

Researchers can adapt focus groups to various topics and settings, from academic research to market research.

The moderator can conduct focus groups quickly, making them a valuable tool for gathering data in a short amount of time.

Small sample size

Focus groups usually involve a small number of participants. The opinions of a focus group may not represent the broader population.

Potential bias

Group dynamics can influence the opinions and attitudes of a focus group, so they may not reflect the opinions of individual participants. 

Limited scope

Focus groups may only provide insights into a specific topic or product instead of broader insights into consumer behavior or attitudes.

Time-consuming

Conducting a focus group can be time-consuming, as it requires organizing and scheduling participants, setting up a location, and analyzing the data.

Interpretation

The interpretation of focus group data can be subjective and dependent on the researcher's perspective and biases.

Researchers should use focus groups and other research methods to ensure comprehensive and accurate findings.

• How do you run a focus group?

Here are some steps to follow when running a focus group:

Before planning your focus group, define your research objectives and determine what you hope to achieve through the focus group.

Determine your target audience by categorizing them with common characteristics to provide the necessary insights.

Identify potential participants that fit your target audience, offer an incentive to encourage participation, and recruit them for the focus group. 

Select a skilled moderator to facilitate the discussion and keep it focused. The moderator should understand qualitative research techniques and have good interpersonal skills.

Develop a discussion guide outlining the questions for the focus group. The questions should elicit insights and opinions from participants on the research objectives.

Hold the focus group in a comfortable, quiet location. Introduce the moderator and explain the purpose of the focus group. The moderator should guide the discussion, asking questions from the discussion guide and encouraging participation from everyone.

Record the discussion using audio or video recording equipment. Consider taking notes during the discussion to capture critical points.

Transcribe the audio or video recording and analyze the data to identify patterns and themes. 

Use the data to draw conclusions and make recommendations based on the research objectives. Use techniques such as content analysis , thematic analysis , or grounded theory to identify patterns and themes in the data.

Prepare a report summarizing the findings of the focus group and provide recommendations based on the research objectives.

Follow these steps to conduct a successful focus group, uncover valuable insights, and achieve your research objectives.

• Five sample focus group questions

Here are some sample focus group questions that you could use in different research contexts avoiding leading questions and emphasizing open-ended questions:

1. Exploring a new product or service:

What are your first impressions of this product/service?

What do you like/dislike about the product/service?

How does this product/service compare to similar products/services?

What improvements could we make to the product/service?

2. Understanding consumer behavior:

What factors influence your decision to purchase a product/service?

How do you typically research products/services before making a purchase?

How do you feel about the pricing of products/services?

How do you use technology when shopping for products/services?

3. Evaluating the effectiveness of a program or intervention:

What do you think are the strengths of the program/intervention?

What challenges have you faced in participating in the program/intervention?

How has the program/intervention impacted your life?

What changes would you recommend to improve the program/intervention?

4. Developing marketing strategies:

What messages do you think would resonate with your target audience?

What channels do you think are most effective for reaching your target audience?

What motivates your target audience to make a purchase?

How do you think your target audience perceives your brand?

5. Exploring social issues:

What are your attitudes toward [topic]?

How has [topic] impacted your life or those you know?

What are some potential solutions to address [topic]?

What are some barriers to addressing [topic]?

These are just a few examples of questions that you could use in focus groups. Carefully design questions relevant to the research objectives that elicit meaningful participant insights.

• Techniques of data collection depend on various factors like whether the data required is quantitative or qualitative.
• The data could be primary data or secondary data.
• Various techniques of data collection for questionnaire, sampling, field study, survey, case study, etc
• It is a detailed account of a single social phenomenon.
• Offers a holistic view on the subject.
• Particular situations and incidents like riots and conflicts are more appropriate for this method as they require an in-depth study.
• The case study method is a very popular form of qualitative analysis.
• Pauline V. Young describes case study as “a comprehensive study of a social unit be that unit a person, a group, a social institution, a district or a community.”
• Case study method results in fruitful hypotheses along with the data which may be helpful in testing them, and thus it enables the generalised knowledge to get richer and richer.
• The limitation of this method : Read Bain does not consider the case data as significant scientific data since they do not provide knowledge of the “impersonal, universal, non-ethical, non-practical, repetitive aspects of phenomena.” Real information is often not collected because the subjectivity of the researcher does enter in the collection of information in a case study.
• Also there is danger of false generalisation.

FOCUS GROUP TECHNIQUE

• Mainly used for non-positivist research.
• This is basically bringing together a group of people to have an extensive and free flowing discussion relating to the focus issue.
• The moderator in the discussion keeps it on the desired focus.
• The usual procedure is to tape record the conversation and analyse them later.
• Usually, there is no structure or discussion pattern.
• Observation bias is significant in Focus group exercise as compared to Participant Observation.

CONTENT ANALYSIS

• The research method is often used in interpretative sociological research.
• It is a methodology for studying the content of communication.
• Earl R Babbie define it as “the study of recorded human communication such as books websites paintings and law.”
• The term Content Analysis is generally applied to the analysis of written communication or visual material rather than interview data.
• This technique produces quantitative data which can be processed by the computer and analysed statistically as well.
• It is criticized for involving subjective judgements which may create data that are quantifiable but not valid.
