Which statements summarize the Belmont Report's key requirements for ethical research?

• A. Requires confidentiality of data at all times.
• B. Requires informed consent and mandates IRB review.
• C. Encourages withholding information from participants.
• D. Has no bearing on modern ethics committees.

Answer: (B)

The central idea being tested is how ethical research is protected through two key safeguards: informed consent and independent review. The Belmont Report established that participants must freely consent to participate, with enough information about the study’s purpose, risks, and benefits, and they must be allowed to withdraw. It also requires that research be reviewed by an institutional review board (IRB) to ensure risks are minimized and participant welfare is protected.

Using these ideas, the best answer says that ethical research rests on obtaining voluntary informed consent and having IRB oversight. The emphasis is on giving participants real information and autonomy, and on independent review to check that risks are reasonable and protections are in place.

Why the other statements don’t fit: while confidentiality and privacy protections are important in practice, Belmont does not present confidentiality as the sole, blanket requirement “at all times.” Withholding information is directly contrary to informed consent and participant autonomy. And Belmont has a strong bearing on modern ethics committees—IRBs and ethics oversight are foundational, not irrelevant to today’s research ethics.
