What is considered "minimal risk" in research according to federal guidelines?

The concept of "minimal risk" in research is defined by federal guidelines as a scenario where the probability of harm or discomfort experienced by participants is not greater than what they would encounter in their daily lives. This definition aims to protect participants by ensuring that the risks involved in research activities are closely aligned with the risks they face in typical situations.

Understanding this criterion is essential for researchers when designing studies involving human subjects. It helps in determining the ethical boundaries of research and in justifying the need for informed consent. In practice, this means that research protocols should be carefully reviewed to assess whether the risks are indeed minimal and do not impose unnecessary burdens on participants.

Other options may misinterpret the definition of minimal risk, as they either suggest higher levels of risk than what is considered acceptable or focus on specific research methodologies rather than the broader definition of risk in everyday contexts.
