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 telephone-assisted survey is a structured data-collection method in which a trained interviewer administers a standardised questionnaire to respondents over the telephone, often supported by Computer-Assisted Telephone Interviewing (CATI) software. It combines the efficiency of remote administration with the response-quality advantages of live interviewer guidance, making it widely used in social, public-health, market-research, and political polling contexts.
