Explicit consent. Participants give consent by answering a specific question about their willingness to participate. This may be done in written (consent form) or oral form.
Some participants, although not legally competent, are able to make judgment about their participation themselves. This is the case for teenagers and some mentally impaired individuals, for instance. The assent formgives them an opportunity to express their agreement to participate in research in writing, beyond the consent given by a legal guardian or parent. Although the assent is not legally binding, and does not dispense a researcher from obtaining consent from a parent or legal guardian, it is advisable as sound ethical practice. It reinforces the voluntary nature of participation.
Active consent. Participants indicate their willingness to participate by agreeing to a specific statement, and then are included in the study. This is the most common, and recommended, form of consent for research.
Please use the template informed consent formprovided in this site to obtain explicit, active written consent. If the participants are not considered legally competent, a parent or legal guardian has to give consent on their behalf. The form for parental or legal guardian consentgives explicit, active written consent for their charge to participate in research. Please be aware that once they become legal adults, children may revoke the consent given by a parent or legal guardian.
