What does federal regulation state about documentation of minors' assent in research?

Federal regulations specify that documentation of minors' assent is not universally required. Instead, it allows for flexibility depending on the context of the research and the judgment of the investigator and the Institutional Review Board (IRB). In many cases, researchers are encouraged to obtain assent from minors when possible; however, they are not obligated to document this assent formally. This nuanced approach acknowledges that assent is important and respects the developing capacities of minors, yet it does not impose a rigid requirement for formal documentation.

The other answer choices suggest stricter conditions. For instance, claiming that documentation is mandatory in all studies does not align with the federal guidelines that provide discretion to researchers. Storing documentation permanently is not required either; the regulations do not specify a permanent storage requirement for assent documentation. Lastly, the notion that documentation is only necessary for high-risk studies misrepresents the general expectation; while higher-risk studies might have different protocols, the lack of a universal requirement remains regardless of risk level.
