Which aspect does IRB primarily focus on regarding research involving human subjects?

The primary focus of an Institutional Review Board (IRB) is on the rights and welfare of human subjects involved in research. This is in alignment with ethical standards designed to protect participants from harm and ensure that their participation is based on informed consent. The IRB reviews study protocols to ensure that risks are minimized and that any potential benefits justify those risks.

This focus concerns various aspects, such as ensuring that participants are fully informed of the nature of the study, potential risks, and their right to withdraw at any time without penalty. The protection of vulnerable populations is also a significant priority, as these groups may require additional safeguards to ensure their rights and welfare are adequately protected.

While the scientific validity of the research and financial implications might be relevant in broader project evaluations, these factors do not take precedence over the ethical responsibility to safeguard human subjects. Similarly, marketing strategies, although important for dissemination of research findings, do not relate to the ethical conduct of research involving human subjects. This clear ethical focus underscores the critical role that IRBs play in maintaining the integrity and safety of research studies.
