What type of consent requires signatures only from those who do not agree to participate?

1. Informed consent

2. Active consent

3. Passive consent

4. Explicit consent

The correct answer is: Passive consent

The type of consent that requires signatures only from those who do not agree to participate is classified as passive consent. This approach allows individuals to be included in a study or program by default unless they explicitly opt out. It differs from other consent types in that it assumes participation unless a participant takes action to withdraw, which often means sending back a signed form to indicate non-participation. In contrast, informed consent involves providing participants with detailed information about the study so that they can make an educated decision about their involvement, necessitating active agreement from those who choose to participate. Active consent requires positive affirmation from participants, meaning they must actively sign or communicate their agreement to be involved in the study. Explicit consent entails a clear and direct agreement typically involving a signed document for specific actions or participation, rather than relying on a passive approach. This clarity distinguishes passive consent as the unique method where only those who decline are required to provide a signature.
