Advantages of Unstructured Interviews
Valid, in-depth data is the biggest strength of unstructured interviews. Interpretivists love this method because it produces rich qualitative information that helps researchers achieve verstehen - truly understanding what life is like from the respondent's perspective.
The informal nature helps build rapport and trust between interviewer and interviewee. This comfortable atmosphere encourages people to be more honest and open, especially when discussing sensitive topics. It's much easier to check that both parties understand questions and answers properly.
Flexibility and control benefit both researcher and respondent. Unlike structured interviews, the questions flow naturally from the interviewee's responses, giving them more freedom to express their views. This often leads to unexpected insights that generate new hypotheses and theories.
Remember: Elizabeth Bott's study of 20 families and Paul Willis's research with 12 lads are classic examples of successful unstructured interview research.
Sensitive groups are more likely to participate when they feel at ease with sympathetic interviewers. This makes unstructured interviews particularly valuable for researching vulnerable populations or taboo subjects that structured methods might struggle to explore effectively.
