What does "a priori risk assessment" involve?

A priori risk assessment involves evaluating the potential risks associated with a research project before the actual research begins. This proactive approach is critical for ensuring that potential hazards to participants are identified and addressed in advance, thereby enhancing the ethical conduct of research.

By conducting an a priori risk assessment, researchers can anticipate problems and develop strategies to mitigate identified risks, ensuring the safety and well-being of participants. This process allows institutions to comply with ethical standards and regulatory requirements, ensuring that human subjects are protected throughout the research lifecycle.

In contrast, evaluating risks after research completion would not provide protection for participants during the study; collecting data on previous studies might inform risk assessments but does not occur prior to initiating research; and reviewing participant feedback on risks pertains to post-study evaluations rather than preemptive assessments. All of these activities happen at different phases and serve different purposes in the research process.
