Which data collection method would most likely yield in-depth, descriptive accounts of participants' experiences?

• A. Structured interview
• B. Semi-structured interview
• C. Postal questionnaire
• D. Unstructured interview

Answer: (D)

Focusing on collecting rich, descriptive accounts of people's experiences, the unstructured interview stands out. In this format the conversation flows with little constraint: participants describe their experiences in their own words, and the interviewer can follow topics as they emerge, ask probing questions, and explore meanings, contexts, and feelings in depth. This openness yields detailed narratives and nuanced insights that aren’t easily captured by fixed questions or brief responses. Structured interviews use predetermined questions and fixed response options, which tends to produce short, standardized answers and limits how deeply a participant can elaborate. Semi-structured interviews keep a guide but still allow some flexibility, so they can capture more depth than structured formats, yet data often remain somewhat guided and comparable across interviews. Postal questionnaires typically rely on written, often closed-ended or brief open-ended responses, which seldom provide detailed personal narratives. For in-depth, descriptive accounts of experiences, the unstructured interview is the best fit.
