Ethical Practices and Protection of Research Participants
What this domain measures
This domain tests your command of the ethical framework governing human subjects research: the principles of respect for persons, beneficence, and justice, and how they translate into informed consent, risk minimization, privacy protection, and equitable selection. Expect questions that present an ethically ambiguous scenario and ask for the most appropriate action.
Core concepts to know
- Informed consent: voluntary, informed, and ongoing. It requires comprehension, not just a signature. Special protections apply to vulnerable populations (children, prisoners, cognitively impaired adults, pregnant women).
- Risk-benefit analysis: risks must be minimized and reasonable in relation to anticipated benefits.
- Equitable selection: participants should be chosen fairly; burden and benefit should not fall disproportionately on one group.
- Privacy and confidentiality: data minimization, secure storage, and limits on access.
- IRB/IEC authority: approval before initiation, continuing review, and reporting of unanticipated problems and protocol deviations.
- Vulnerability and coercion: undue influence, therapeutic misconception, and power imbalances in recruitment.
Traps to watch
- Treating a signed form as proof of valid consent when comprehension or voluntariness was compromised.
- Choosing the "efficient" option that bypasses IRB review or consent requirements.
- Missing that a protocol deviation affecting participant safety must be reported, even if no harm occurred.
- Overlooking that consent is a process, not a single event.
Rule of thumb
When two answers seem plausible, choose the one that preserves participant autonomy and adds an oversight step (report, consult, re-consent) rather than the one that resolves the issue quietly.
Worked example
A participant signs consent but later says they did not understand the randomization. The correct response is to re-educate and re-document consent, not to proceed on the theory that the signature is sufficient. Comprehension failure undermines the validity of consent.
