Questionnaires 3. Structured and unstructured questions: advantages and disadvantages of each type

Types of questions There are two main types Structured (Closed responses) – use when the response falls into easily defined categories. Rating scales are structured questions too. Unstructured (Open responses) – use when the responses could be quite varied and you can’t decide what the responses might be.

Advantages of structured questions Quick and easy to answer Answers are easier to analyse Possible responses makes the meaning of the question clearer

Disadvantages of structured questions Requires knowledge of likely responses Restricts possible answer (inclusion of “other” category gives no information) Respondents with no opinion or knowledge provide an answer anyway.

Advantages of unstructured questions Permits an unlimited number of answers Allows detailed answers Allows unanticipated answers

Disadvantages of unstructured questions Coding responses is difficult and time consuming The questionnaire takes longer to complete Answers can be irrelevant if the question is misunderstood.
