概要	A face-to-face structured interview is a data collection method in which a trained interviewer meets each respondent in person and asks a fixed set of questions in a predetermined order, recording responses verbatim or using a closed-response format. It combines the response-rate advantages of personal contact with the standardization of a fixed instrument, making it a cornerstone of large-scale social, health, and policy surveys.	An online structured interview applies the classical structured interview protocol — a fixed set of predetermined questions asked in a fixed order — via internet-mediated channels such as video conferencing, synchronous chat, or email. Every participant receives the exact same questions, enabling systematic comparison across respondents while eliminating geographic barriers. It combines the standardization benefits of face-to-face structured interviewing with the reach, cost efficiency, and scheduling flexibility of online data collection.
