After a study has received initial ethics approval and data collection has begun, a researcher who wants to make a significant change to the research procedure must obtain additional formal approval from the ethics review board before implementing that change.

If a researcher needs to make anything other than a minor change to their study after it has begun, they must seek additional formal approval from the Institutional Review Board (IRB) or relevant ethics committee before implementing the modification to the research design or procedure.

A researcher's ethical obligations do not end once a study receives institutional approval. It is critical to adhere strictly to the submitted research protocol throughout the study. If any adjustments beyond minor changes are required, the researcher must seek additional approval from the institutional review board before implementing those modifications.

Protocol Modification Approval

During an ongoing research study, investigators must continuously monitor their participants for any unanticipated reactions. If participants exhibit unexpected distress or negative responses, researchers should seek their feedback during the debriefing process and must be prepared to adjust the study's procedures to ensure ethical compliance and participant safety.
