What is the purpose of a consent form in research?

• A. To document that the participant has been informed and agrees to participate.
• B. To ensure researchers publish results regardless of consent.
• C. To mandate compliance with all study procedures.
• D. To document participants' voluntary withdrawal from the study after enrollment.

Answer: (A)

Consent forms capture informed voluntary participation. They provide a written record that explains the study’s purpose, procedures, potential risks and benefits, confidentiality protections, and the participant’s right to withdraw at any time. This supports respecting people’s autonomy and ensures researchers obtain a genuine, informed agreement, which is also required for ethical oversight and regulatory compliance. The form isn’t about guaranteeing publication, nor about mandating how participants must follow procedures; and while it may mention withdrawal, the main purpose is documenting informed consent.
