Which step involves ensuring protection of participants?

Selecting the research design is a crucial step in ensuring the protection of participants in a study. This phase involves deciding how the research will be structured and conducted, including considerations for participant safety and ethical guidelines. A well-designed study incorporates protocols that identify risks, ensure informed consent, and outline confidentiality measures, all aimed at safeguarding participant welfare.

During the research design process, researchers must evaluate potential risks associated with their study and implement strategies to minimize those risks. This could include selecting appropriate populations, defining intervention protocols, and instituting oversight mechanisms like Institutional Review Boards (IRBs) to monitor participant protection.

While data collection, hypothesis development, and measurement methods are essential elements of research, they primarily focus on the operational aspects of the study rather than the foundational ethical considerations, making the selection of research design the most critical step in protecting participants.
