Which data collection method is used to obtain in-depth information from a single knowledgeable community member?

• A. Key informant interviews
• B. Focus groups
• C. Health surveys
• D. Participant observation

Answer: (A)

Key informant interviews involve one-on-one, in-depth conversations with a person who has specialized knowledge about the community. This approach yields rich, detailed information about beliefs, needs, and barriers that might not emerge in group settings or from standardized surveys. It allows you to ask open-ended questions and follow-up probes to explore nuances and context specific to that informant’s experiences. Focus groups gather insights from several participants together, which can surface shared themes but may dilute the depth of any single perspective and can be influenced by group dynamics. Health surveys collect broad, often quantitative data from many people, providing general patterns rather than deep, contextual understanding. Participant observation involves the researcher immersing in the community to observe behaviors and interactions, generating valuable contextual data through watching rather than interviewing a single informant. For obtaining detailed information from a knowledgeable community member, the in-depth, one-on-one interview approach is the best fit.
