· Interviewer can explain the questions and overcome illiteracy problems
· Data can be seen as reliable as all the participants are answering the same questions
· These interviews use pre-coded questions, which make the data easier to compute and analyse than the data gained in unstructured interviews
· The interviewer has little interaction with the participant so there is less chance of interviewer bias than in unstructured interviews.
· The structure of the interview means the interviewer can’t probe and ask further questions, so the data isn’t as rich
· They are more time consuming and expensive than other methods such as postal questionnaires
· There is still the risk of interviewer bias
