Decision workbook and example

Choose a coherent approach

Qualitative work investigates meaning, experience and processes, but not through one universal method. Explain the epistemological position and analytical approach. Thematic analysis, grounded theory and phenomenology carry different commitments.

Explain sampling and positionality

Document why people or settings were selected and describe access limitations. Interview counts are not governed by a universal number. Preserve reflexive notes about researcher assumptions and relationships with participants.

Preserve context in collection

Pilot open questions and follow-up prompts. Establish appropriate arrangements for recording, quotations and retention. Document transcription and translation choices that affect meaning and remove identifying details appropriately.

Make interpretation traceable

Connect codes, extracts, analytical notes and category revisions. Software organizes materials but does not establish the validity of an interpretation. Use coder agreement or saturation only when coherent with the chosen approach and clearly defined.

Report within methodological limits

COREQ addresses reporting interviews and focus groups; other methods may need other guidance. Quotations should support interpretation and respect privacy. Examine contradictory cases and alternatives, and do not infer statistical generalizability automatically from purposive sampling.

Practical research checklist

  • Explain the methodological approach.
  • Document sampling and researcher role.
  • Connect codes, evidence and interpretations.
  • Use appropriate reporting guidance.

Worked case and implementation decisions

The following is a fictional teaching case. Do not use its numbers or wording as actual study findings.

For a fictional support-experience study, “Describe a recent situation when seeking help was easy or difficult” is less leading than “Why is university support poor?” The synthetic excerpt “I did not know whom to ask” may receive the initial code access-route uncertainty; one code is not a final theme. Record context, researcher position, sampling and interpretive memos. Saturation or adequacy criteria must fit the actual methodological approach rather than a universal interview number.
