Which method involves a well-trained interviewer asking semi-structured questions in person?

The method that involves a well-trained interviewer asking semi-structured questions in person is referred to as an in-depth interview. This qualitative research technique allows for a deep exploration of the interviewee's thoughts, feelings, and motivations regarding a particular topic. The semi-structured format provides flexibility; while the interviewer has a guideline of questions, they can adapt the conversation to delve deeper into relevant areas that emerge during the dialogue.

This depth of interaction is particularly beneficial for gaining insights that may not be captured through more rigid methods, such as surveys, which typically rely on fixed responses. In-depth interviews are ideal for understanding complex behaviors or attitudes, as the interviewer can probe further based on the participant's responses, creating a dynamic and responsive discussion. The face-to-face nature of this method also helps to build rapport, which can facilitate more open and honest communication from the interviewees.
