Risks and Safeguards in Social-Behavioural Research With Adults With Developmental Disabilities: A Qualitative Systematic Review.
Katherine McDonald, Madison Brodeur, Ariel Schwartz
PMID 40052433WHAT IT FOUND
Research risks for adults with developmental disabilities are largely the same as for others, but fatigue, privacy invasion, and confusing researcher boundaries need specific attention.
Safeguards should prioritize participant choice, respect, and clear communication to ensure ethical inclusion rather than restriction.
Key findings
01Most risks identified in social-behavioural research with adults with developmental disabilities are similar to those for other populations, though fatigue and sensory sensitivity require specific management.
02Privacy and confidentiality are threatened by home-based or prolonged observation methods, and mandatory reporting requirements can create new risks like re-traumatisation if not handled with support.
03Effective safeguards include reducing session length, allowing breaks, offering choices in data use, and maintaining clear, respectful researcher-participant boundaries.

What it does not show
The review included only 23 manuscripts, a relatively small evidence base. Most included studies were retrospective reflections by researchers rather than direct reports from participants with disabilities. The review excluded grey literature and did not analyse risk-benefit ratios or group-level risks. The focus was strictly on social-behavioural research, so findings may not apply to biomedical trials.
Declared interests
The authors declare no conflicts of interest. The work was funded by the MGH Institute of Health Professions and the Patient-Centered Outcomes Research Institute.
The easy way to misread this
Do not assume this review proves these safeguards reduce harm or improve retention. The included studies were mostly descriptive reflections, not controlled trials, so the effectiveness of these strategies remains untested.
