概要	A telephone-assisted semi-structured interview is a qualitative data collection technique in which a researcher conducts a guided conversation with a participant over the telephone, using a pre-designed topic guide that balances predetermined questions with freedom to probe and explore. It combines the flexibility of semi-structured interviewing with the geographic reach and logistical convenience of telephone communication, making it widely used in health, social, and organizational research.	A face-to-face semi-structured interview is a qualitative data collection technique in which a researcher meets a participant in person and follows a prepared topic guide of open-ended questions while retaining the flexibility to probe, reorder, and explore emerging themes. It combines the consistency of a predetermined agenda with the depth and responsiveness of an open dialogue, making it one of the most widely used methods in qualitative and mixed-methods research across the social, health, and educational sciences.
