What does the statement "Please fill out the following questionnaire. It will take you 15-20 minutes" primarily describe in a consent form?

The statement "Please fill out the following questionnaire. It will take you 15-20 minutes" clearly outlines the expectations placed on participants. It specifies the action required from them, which is to fill out a questionnaire, and provides an estimate of the time commitment involved. This detail is crucial in a consent form as it ensures that participants are fully informed about what their participation entails before they agree to take part in the study.

While there are other important aspects of consent forms, such as advising participants about risks, discussing potential benefits, and confidentiality terms, this statement is solely focused on the participants' obligations and what they need to do to engage with the research. Thus, it effectively communicates the expectations set for them in the context of participation.
