What is the purpose of obtaining parental permission in research involving minors?

Obtaining parental permission in research involving minors is fundamentally aimed at protecting those individuals who are unable to legally provide informed consent on their own behalf. Minors generally do not possess the legal capacity to consent to participation in research due to their age and limited understanding of the potential risks and benefits involved. By requiring parental permission, researchers ensure that a responsible adult has made an informed decision about the child's participation in the study. This approach aligns with ethical standards in research, emphasizing the welfare and rights of vulnerable populations, such as children.

While other options touch on various aspects of research, they do not encompass the primary reason parental permission is mandated. Limiting researcher liability or facilitating faster data collection does not address the core ethical concern of safeguarding the interests of minors. Also, adhering strictly to the study protocol is important, but it is secondary to the ethical requirement of obtaining consent from guardians.
