What do we call a written set of questions for research participants?

A written set of questions for research participants is referred to as a questionnaire. A questionnaire is specifically designed to gather information from respondents, and it can be used in various research contexts to collect quantitative or qualitative data. The questions within a questionnaire can range from multiple choice to open-ended formats, allowing researchers to gain insights into participants’ opinions, behaviors, or experiences.

In contrast, the other options, while related, serve different purposes. An interview typically involves direct interaction between the researcher and the participant and may be more conversational in nature. A survey is broader and can encompass various data collection methods, including questionnaires and interviews, but does not exclusively refer to written questions. A feedback form is usually a structured way for recipients to provide their opinions about a specific experience and is often narrower in focus compared to a questionnaire, which can cover a wider range of topics.
