Interviews are a type of self-report technique that involve an interviewer asking questions (generally on a one-to-one basis) and recording responses. There are different types of interview: structured (where the interviewer has a set list of questions with which to lead the conversation and a framework which will be rigidly adhered to); semi-structured (where the interviewer may have a list of topics or questions, but has extra flexibility to develop the conversation further, should participant responses lead to deeper/more detailed discussion); and unstructured (which are more like a conversation with no set questions).
