Tóm tắt	Vulnerable populations are groups with limited capacity to protect themselves due to age, cognitive ability, institutional dependency, or social circumstances. Regulatory frameworks in the U.S. (45 CFR 46 Subparts B, C, D) and internationally identify specific vulnerable populations—children, prisoners, pregnant women, cognitively impaired individuals—and mandate additional ethical protections beyond standard informed consent. These protections include obtaining informed consent from surrogate decision-makers (parents, guardians), additional assurances of minimal risk, and enhanced monitoring for safety. Research ethics committees apply heightened scrutiny to studies involving vulnerable populations and may deny approval if special protections are inadequate.	Participant debriefing is a post-study conversation or disclosure providing information to participants after research participation concludes. Debriefing serves multiple ethical purposes: (1) explaining the research aims and design, (2) revealing any deception (if applicable), (3) addressing misconceptions, (4) offering support if the research caused discomfort, (5) providing information about study findings, and (6) ensuring participants understand their rights (e.g., right to withdraw data). Debriefing is especially important in research involving deception (participants must learn the truth), sensitive topics (participants may experience distress), or invasive procedures (participants deserve explanation). The American Psychological Association's Ethical Code, ESOMAR guidelines, and international research ethics frameworks emphasize debriefing as a core protective procedure.
