What is the primary purpose of informed consent in research?

• A. Describing the study to the participant and obtaining permission to include them
• B. Ensuring confidentiality of data
• C. Determining participant compensation
• D. Measuring participant eligibility for the study

Answer: (A)

Informed consent centers on respecting a participant’s autonomy by ensuring they understand what the study involves and can decide, of their own free will, whether to take part. The best description is that it involves describing the study to the participant and obtaining their permission to include them. This captures the essential act of informing and securing voluntary agreement. While aspects like confidentiality, compensation, and eligibility are important parts of conducting research, they are not the primary purpose of informed consent themselves; they are topics that may be covered within the consent process, but the core aim is enabling an informed, voluntary decision and offering the right to withdraw at any time.
