When should researchers seek consent to participate in research?

• A. At any time during the course of the research.
• B. After the participant has completed the research activity.
• C. Prior to commencing participation in the research.
• D. Whenever the researcher chooses.

Answer: (C)

Obtaining consent before participation is essential to respect a person’s autonomy and ensure they understand what the study involves. The initial consent should happen prior to any data collection or involvement, so participants can decide with clear information about procedures, risks, benefits, and their right to withdraw. If circumstances change or new information arises, researchers may seek ongoing or updated consent, but participation should not start without it. The other options miss this essential timing: consent after completion cannot govern participation, and leaving consent to the researcher’s discretion undermines voluntariness and informed participation.
