When are structured interviews most useful?

Structured interviews work best in research that relies on a well-defined theoretical framework. In such cases, the interviewer can devise questions based on existing research, ensuring that new data builds upon prior knowledge. This type of interview is particularly useful when the researcher is confident about which questions are important and can accurately predict the kind of information needed.

Unlike unstructured interviews, which allow for more open-ended responses and probing questions, structured interviews are designed to collect specific data. This approach is ideal when the goal is to obtain consistent, comparable responses from multiple participants. It is less suitable for research contexts that are exploratory or where the researcher is unsure about which questions might yield the most useful data.

Advantages of structured interviews

One key advantage of structured interviews is that they provide focus. When the conversation follows a strict set of questions, there is less chance for the interview to veer off-topic. By sticking to the script, the interviewer ensures that the conversation remains relevant and aligned with the research goals.

Structured interviews also make it easier to compare responses across different participants. Since everyone is asked the same questions in the same order, the data collected is uniform and more straightforward to analyze. This consistency is a major benefit, particularly when large groups of people are interviewed. Researchers can efficiently group responses and look for patterns or commonalities.

In terms of logistics, structured interviews are often easier to organize. Since the interviewer doesn’t need to improvise or follow up with new questions, it requires less skill and experience to conduct a structured interview. Interviewers can be easily trained to follow a pre-written guide, making it feasible for research teams to delegate this task to assistants.

Another practical advantage is that structured interviews can be conducted relatively quickly. Since there is a fixed set of questions, the duration of each interview is predictable, making it easier to plan for multiple interviews in a short period. This efficiency is valuable when dealing with large sample sizes.
