Which statement best describes informed consent in psychiatric research?

• A. Coercion is allowed.
• B. Consent is not needed for minimal risk.
• C. Voluntary participation without coercion or undue influence; understanding of risks; ability to withdraw; confidentiality.
• D. Payment is the key.

Answer: (C)

Informed consent in psychiatric research rests on voluntary participation without coercion or undue influence, understanding of the risks and procedures, the ability to withdraw at any time, and assurances of confidentiality. This combination protects a participant’s autonomy and safety, which is especially crucial in psychiatry where vulnerability may be present. Coercion invalidates consent, so that option isn’t acceptable. Consent is still required for minimal-risk research, though there are regulatory allowances for specific waivers in limited cases; the idea that consent isn’t needed in general is incorrect. Payment can influence enrollment but does not substitute for informed, voluntary agreement or replace understanding of risks and rights.
