What is required to obtain consent for use of data in research?

• A. Verbal approval with no documentation.
• B. Consent is not required for de-identified data.
• C. Purpose and procedures are not disclosed.
• D. Clear disclosure of purpose, procedures, risks, benefits, confidentiality, and voluntary participation.

Answer: (D)

Obtaining informed consent in research means giving people enough information to decide whether they want to participate, and doing so in a way that respects their autonomy. The best choice lists the essential elements that must be disclosed: the purpose of the research, the procedures involved, any potential risks and benefits, how confidentiality will be protected, and the fact that participation is voluntary. This combination ensures the participant can understand what they’re agreeing to, weigh the implications, and decide freely, with there being a record of that consent.

Verbal approval without documentation falls short because it doesn’t provide a verifiable record or ensure that all necessary information was communicated and understood. Saying that consent isn’t required for de-identified data isn’t universally accurate either; while de-identified data can reduce risk and may allow use without consent in some contexts, the consent process itself, when used, must include the full disclosures listed above.
