What does it mean when a study can be reviewed under expedited procedures?

When a study can be reviewed under expedited procedures, it specifically indicates that the research involves minimal risk to participants. The expedited review process is designed for studies that present no greater risk than those already established in existing research guidelines. Such studies might include certain types of behavioral research or the use of data collected in a non-invasive manner.

The rationale behind this expedited review is to ensure that research can still proceed efficiently while safeguarding the welfare of participants. By qualifying for an expedited review, the research does not require the full board review that is typically reserved for studies presenting more than minimal risk. Understanding this criterion is crucial for researchers planning studies involving human subjects, especially within vulnerable populations, such as prisoners. The other options do not align with the concept of expedited review: immediate approval isn't guaranteed through this process, ethical standards are still mandatory in all research studies, and comprehensive data collection doesn't inherently relate to the level of risk involved.
