A focus group is a structured group discussion of 6–10 participants, facilitated by a trained moderator, used to collect rich qualitative data on attitudes, perceptions, and experiences. Focus groups are a powerful data collection method for PhD dissertations and academic research, generating interactive data that individual interviews cannot produce.
What Is a Focus Group in Research?
Focus groups were developed in the 1940s by sociologist Robert Merton as "focused interviews" with groups. Today they are widely used in social sciences, healthcare, marketing research, education, and policy research. Their defining characteristic is that data emerges from group interaction — participants respond to each other, build on ideas, challenge views, and share diverse perspectives.

Step-by-Step: How to Conduct a Focus Group
Step 1: Define Your Research Purpose
Clarify what you want to explore. Focus groups are ideal for: exploring shared attitudes; understanding community perspectives; generating hypotheses for further study; evaluating programmes or policies; and exploring meanings behind behaviours.
Step 2: Design the Discussion Guide
A focus group discussion guide is a structured but flexible list of 5–8 open-ended questions, organised from general to specific. It includes:
- Opening question: Easy, non-threatening ("Tell me about your experience with X")
- Introductory questions: Introduce the main topic broadly
- Transition questions: Move towards key questions
- Key questions: Core research questions (3–5 questions, most time here)
- Closing question: "Is there anything important we haven't discussed?"
Step 3: Recruit Participants
Recruitment should be purposive — select participants who have direct experience with or knowledge of your research topic. Key criteria:
- Define inclusion criteria clearly
- Avoid including people who know each other well (may inhibit honest discussion)
- Recruit slightly more than needed (over-recruit by 2–3 to allow for no-shows)
- Provide clear participant information and obtain informed consent
Step 4: Set Up the Environment
Choose a neutral, comfortable venue where participants can speak freely. Arrange seating in a circle or horseshoe so all participants can see each other. Ensure privacy and confidentiality. Set up audio/video recording equipment with participants' consent.
Step 5: Facilitate the Discussion
The moderator's role is to guide — not lead — the discussion:
- Open with a warm welcome and ground rules (confidentiality, everyone's voice matters, no right/wrong answers)
- Use probes to deepen responses: "Can you tell me more about that?" "Does anyone else feel the same way?" "What do others think?"
- Ensure all voices are heard — invite quiet participants and manage dominant speakers
- Remain neutral — do not express personal opinions or lead participants
- An observer/note-taker should document non-verbal cues and interaction patterns
Step 6: Record and Transcribe
Audio or video record the session (with consent). Transcribe recordings verbatim, noting pauses, laughter, or simultaneous speaking. Note-taker notes on group dynamics supplement the transcript.
Online Focus Groups for PhD Research
If in-person focus groups are not feasible, online focus groups via Zoom, Teams, or Google Meet are increasingly accepted in academic research. Use breakout rooms for smaller groups, ensure participants have quiet environments, and use the chat function as a backup for shy participants. Note that online formats may reduce interaction spontaneity but increase geographic reach and convenience.

How to Analyse Focus Group Data
| Step | Activity | Output |
|---|---|---|
| 1 | Transcribe recordings verbatim | Full text transcripts with speaker labels |
| 2 | Read transcripts multiple times (immersion) | Annotated transcripts, initial impressions |
| 3 | Open coding — label meaningful segments | List of initial codes |
| 4 | Group codes into categories | Categorised codebook |
| 5 | Develop themes across groups | 3–6 overarching themes |
| 6 | Write up themes with illustrative quotes | Findings chapter narrative |
Common Mistakes to Avoid
- Using leading questions that suggest expected answers
- Allowing one or two participants to dominate the discussion
- Not piloting the discussion guide before the actual focus groups
- Failing to record or transcribe sessions properly
- Treating focus group data as equivalent to individual interview data without acknowledging the social construction of responses

A focus group is a guided group discussion led by a trained moderator, involving 6–10 purposively selected participants who share relevant characteristics. It is a qualitative data collection method used to explore attitudes, opinions, perceptions, and experiences on a specific topic. Focus groups generate data through interaction — participants build on each other's comments, producing richer data than individual interviews.
The ideal size for a focus group is 6–10 participants. Groups smaller than 5 may lack sufficient interaction and diversity of views; groups larger than 12 become difficult to manage and some voices get marginalised. For sensitive topics, smaller groups (5–7) are often preferable. Most studies run 3–5 focus groups to achieve thematic saturation across different participant sub-groups.
The number of focus groups depends on your research purpose and the diversity of your target population. Most qualitative studies use 3–6 focus groups. You should continue until theoretical saturation is reached — when new groups produce no new themes. In practice, running separate groups for different sub-populations (e.g., male/female, urban/rural) ensures adequate representation of diverse perspectives.
Focus group data is typically analysed using thematic analysis or framework analysis. Steps: (1) Transcribe recordings verbatim; (2) Read transcripts multiple times to become familiar with the data; (3) Apply initial (open) codes to segments; (4) Group codes into categories; (5) Develop themes that capture the essence of participant views; (6) Write up themes with illustrative quotes. Note that interaction patterns (disagreements, consensus moments) are also data in focus groups.
Individual interviews explore personal, in-depth narratives — suitable for sensitive topics or unique experiences. Focus groups generate data through interaction and group dynamics — ideal for exploring shared experiences, community norms, or consensus/disagreement on issues. Focus groups are more time-efficient (collect from 6–10 people at once) but may inhibit disclosure of sensitive or minority views. Both methods can be used together in a multi-method qualitative study.
