What constitutes coercion in obtaining informed consent?

Coercion in obtaining informed consent is characterized by actions that force or unduly influence individuals to participate in research against their better judgment or without true voluntary agreement. When researchers apply pressure, manipulation, or significant incentives that create an undue influence on the participants, this undermines the ethical principle of voluntary participation, which is essential for ethical research practices.

This approach goes against the core of informed consent, which is rooted in respect for the autonomy of individuals. Participants should make decisions based on a clear understanding of what they are consenting to, free from any form of intimidation or overwhelming pressure. The other options presented do not exemplify coercion; offering incentives can sometimes be ethical if it encourages participation without pressure, providing clear information is vital for informed consent, and allowing withdrawal enhances the participant's autonomy and reduces the potential for coercion.
