요약	A telephone-assisted in-depth interview is a qualitative data collection method in which a researcher conducts a lengthy, open-ended, exploratory conversation with a participant via telephone. It preserves the depth and flexibility of face-to-face in-depth interviewing while overcoming geographic and mobility barriers, making it particularly useful when participants are dispersed, housebound, or when travel is impractical.	A structured interview is a data collection technique in which every participant is asked exactly the same pre-specified questions in the same order, using standardized wording. Because the interview schedule is fixed, responses across participants are directly comparable, enabling quantitative aggregation and statistical analysis. It sits at the most standardized end of the interview continuum, between the self-administered questionnaire and the semi-structured interview.
