# Focus Group Methods Focus groups generate data through **interaction**: participants respond to prompts, build on each other’s ideas, and sometimes reveal normative assumptions, vocabularies, and disagreements that individual interviews suppress or never surface. ## When to use focus groups vs interviews Use **focus groups** when group sense-making, consensus/dissensus, or cultural scripts are central—e.g., testing how a community talks about a stigma-laden topic, exploring how teams coordinate, or mapping shared meanings of a policy. Use **individual interviews** when sensitive disclosures, power asymmetries within a peer group, or detailed personal narratives are primary. Avoid focus groups when participants may fear retaliation from others in the room. ## Group composition Aim for **homogeneity on the dimension that drives comfort** (e.g., job role, experience level) and **careful heterogeneity** only when cross-perspective friction is analytically desired. Typical size is **4–8** participants; smaller groups suit complex tasks or vulnerable topics. Over-recruit slightly to handle no-shows. ## Moderator guide development Structure sessions with: (1) welcome, consent, ground rules (respect, confidentiality limits, one speaker at a time); (2) warm-up; (3) 3–5 focused question blocks with planned follow-ups; (4) closing reflection. Questions should invite **concrete examples** (“Tell us about a time…”) before abstract generalizations (“What do people think about…?”). ## Group dynamics as data Track **who speaks, who is silent, who aligns, who challenges**. Silence can mean agreement, fear, or disengagement—follow up ethically. Manage dominant speakers kindly (“Let’s hear from someone who hasn’t spoken yet”). Note laughter, interruptions, and collective corrections; these are analytic material about norms, not mere noise. ## Analysis of focus group data Transcribe **by speaker turn** with minimal identifiers in transcripts used for analysis. Code both **content** (themes) and **interaction** (alignment episodes, storytelling chains). Compare focus group findings with interviews or observations when possible to avoid over-weighting performative public accounts. ## Recording logistics Use multiple microphones when affordable; backup recording when ethical and practical. Obtain explicit consent for recording and clarify that confidentiality cannot be guaranteed among participants—set ground rules accordingly. ## How many groups? There is no magic N. Plan **iterative rounds** until you observe **pattern repetition** and diminishing novelty for your analytic goals (analogous to saturation thinking). Reporting should justify group count by data quality and stability of themes, not by a fixed rule. ## Grounded theory with focus groups Treat each exchange as **comparable incidents**. The moderator should avoid imposing preconceived categories; probe emergent distinctions participants introduce. Memo immediately after each session on hypotheses about categories, conditions, and consequences suggested by interaction patterns. ## Facilitation ethics Do not coerce disclosure; debrief emotionally heavy sessions; offer referrals when appropriate. For industry or workplace groups, clarify whether managers can attend and how that affects candor. ## Checklist - [ ] Focus group fit justified vs individual interviews. - [ ] Composition supports safety and analytic aims. - [ ] Moderator guide balances structure with emergent follow-up. - [ ] Interaction dynamics captured in notes and transcription conventions. - [ ] Confidentiality limits explained; recording consents secured. ## References (starting points) - Krueger, R.
