Which of the following statements is true regarding the regulations that govern research?
The true statement is that research is governed by overlapping federal, state, and institutional regulations, and requirements vary by country and funding source. U.S.-funded human-subjects studies generally must follow U.S. rules (the Common Rule, 45 CFR 46) regardless of where the research is conducted.
The answer
The correct statement recognizes that research regulation is layered, not singular. Human-subjects research in the United States is governed simultaneously by federal law, state law, and each institution's own policies, and the exact requirements depend on where the research happens and who is paying for it. The cornerstone federal rule is 45 CFR 46, commonly called the Common Rule, issued by the Department of Health and Human Services (HHS) and adopted by most federal agencies that fund research. A separate set of rules from the FDA (21 CFR 50 and 56) applies when a study involves drugs, devices, or biologics.
A key point the true statement captures: when a study is U.S.-funded or conducted by a U.S. institution, U.S. regulations follow the research even if the participants and researchers are physically in another country. The foreign site's local laws and ethics committees also apply, so the study must satisfy both frameworks—whichever protections are stronger.
Why the other options are wrong
Typical distractors on this CITI question fail because they oversimplify:
- "A single federal law governs all research." False. No one statute covers everything; oversight is split across HHS, FDA, and other agencies, plus state and institutional rules.
- "Regulations only apply to federally funded research." False. Many institutions extend the Common Rule to all research regardless of funding source, and FDA rules apply based on the product studied, not the money.
- "U.S. rules stop at the border." False. U.S. requirements travel with U.S. funding and U.S. investigators; international research is held to U.S. standards in addition to local ones.
- "Only the IRB decides the rules." False. The IRB applies and enforces the regulations, but it does not create the underlying federal law.
The bigger picture
Under the Common Rule, the Office for Human Research Protections (OHRP) oversees compliance for HHS-funded research, while the FDA oversees regulated products. Institutions receiving federal funds sign a Federalwide Assurance (FWA) committing them to these protections. The day-to-day gatekeeper is the Institutional Review Board (IRB), which reviews and must approve human-subjects research before it begins, weighing risks against benefits and ensuring informed consent.
The practical takeaway for researchers: never assume one rulebook. Before a study starts, you must identify (1) the funding source, (2) the location(s) of the research, (3) the type of subjects and data, and (4) whether an FDA-regulated product is involved. Each of those factors can pull in a different regulatory requirement. The 'true' statement is the one that acknowledges this overlapping, context-dependent structure rather than reducing it to a single law or jurisdiction.
- 1
Does the study involve human subjects or their identifiable data?
If no, the Common Rule generally does not apply. If yes, continue—IRB review is likely required.
- 2
Is it federally funded or conducted at an institution with a Federalwide Assurance?
- 3
Does it involve an FDA-regulated drug, device, or biologic?
- 4
Is any part of the research conducted abroad?
Frequently asked
What federal regulations govern human subjects research?
The primary regulation is 45 CFR 46, the 'Common Rule,' administered by HHS through the Office for Human Research Protections. When a study involves FDA-regulated drugs, devices, or biologics, FDA regulations at 21 CFR 50 (informed consent) and 21 CFR 56 (IRBs) also apply.
What is 45 CFR 46 (the Common Rule)?
It is the U.S. federal policy for the protection of human research subjects. It requires IRB review, informed consent, and special protections for vulnerable populations. It was adopted by numerous federal agencies, which is why it is called the 'Common' Rule, and it was substantially revised in 2018.
Do U.S. research regulations apply to studies conducted abroad?
Yes. When research is funded by the U.S. government or run by a U.S. institution with a Federalwide Assurance, U.S. protections follow the study overseas. Researchers must also comply with the host country's laws and local ethics committee review, meeting whichever standards are more protective.
Who enforces research regulations in the United States?
The Office for Human Research Protections (OHRP) enforces the Common Rule for HHS-funded research, and the FDA enforces its own rules for regulated products. At the local level, each institution's IRB reviews and monitors studies to ensure compliance.
What is the role of an IRB?
An Institutional Review Board reviews research involving human subjects before it starts, and periodically during the study, to ensure risks are minimized, benefits justify the risks, informed consent is obtained, and vulnerable participants are protected. The IRB can approve, require changes to, or disapprove research.
