When conducting research involving children, which practice best protects vulnerable participants?

• A. Not involving guardians in consent
• B. Informed consent from guardians and assent from children, minimizing risk and protecting confidentiality
• C. Not informing participants of risks
• D. Data can be published without confidentiality

Answer: (B)

Protecting vulnerable participants in research, especially children, hinges on obtaining informed consent from guardians and assent from the child, while also minimizing risk and safeguarding confidentiality. Guardians provide consent after being fully informed about the study’s purpose, procedures, risks, and benefits, and the child’s assent shows they agree to participate in language and terms appropriate for their age. This approach respects both parental responsibility and the child’s developing autonomy, creating protections that reduce potential harms and protect privacy.

Choosing not to involve guardians would skip essential ethical and legal protections, and not informing participants of risks undermines their ability to make an informed choice. Allowing publication of data without maintaining confidentiality could expose private information and cause real harm. Together, guardian consent, child assent, risk minimization, and confidentiality protection best shield young participants.
