What does "risk-benefit analysis" entail in the context of human subjects research?

In the context of human subjects research, "risk-benefit analysis" involves a systematic evaluation of the potential risks to participants in a study compared to the anticipated benefits that the research may yield. This analysis is crucial for ethical decision-making, as it helps ensure that the rights and welfare of participants are protected. Ethical guidelines, such as those outlined in the Belmont Report, advocate for researchers to minimize risks and maximize potential benefits as part of their responsibility toward participants.

A thorough risk-benefit analysis enables researchers to identify any possible adverse effects of the research on participants and to weigh these against the possible advancements in knowledge or improvements to public health that the research may produce. This assessment helps in obtaining ethical approval from Institutional Review Boards (IRBs), which is necessary before carrying out human subject research. By prioritizing participant safety while also considering the contributions of the research to society, this analysis plays a foundational role in conducting responsible and ethical research.
