In-depth interviews are characterized by:

• A. Focus groups with 6-10 participants
• B. One-on-one, semi-structured interviews lasting 60-90 minutes with verbatim transcription
• C. Systematic observation with field notes
• D. Document analysis of diaries

Answer: (B)

In-depth interviews aim to uncover rich, detailed understandings of individuals’ experiences, perceptions, and meanings through direct, guided conversation. They are conducted one-on-one using a semi-structured interview guide, which provides consistent topics while allowing flexible probing based on the interviewee’s responses. A key feature is the duration—typically long enough to explore topics in depth, such as 60–90 minutes—so researchers can tease out nuance and context. Transcribing the interview verbatim ensures every nuance, hesitation, and phrasing is captured for thorough later analysis. This combination—single participant, semi-structured format, substantial length, and verbatim transcription—best represents the method. The other descriptions point to different data collection approaches. Focus groups involve multiple participants at once, where group dynamics shape responses. Systematic observation with field notes focuses on watching and recording behaviors in natural settings rather than conducting in-depth conversations. Document analysis of diaries centers on existing documents rather than performing live interviews.
