Sintesi	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 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.
