Semi-structured interviews are a qualitative research method that combines elements of both structured and unstructured interviews. In this approach, the interviewer prepares a set of open-ended questions but remains flexible, allowing for spontaneous follow-up questions based on the interviewee's responses. This format encourages a more natural conversation, enabling deeper insights into the interviewee's thoughts and experiences. These interviews are commonly used in fields like sociology, psychology, and market research. They provide rich, detailed data while still maintaining some consistency across interviews, making it easier to analyze and compare responses.
