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.
Passive consent. Participants are informed of the study, and are considered to agree to participate unless they specifically decline to be included in the study. This procedure is often used in schools that send forms to parents asking them to allow their students to participate in various studies or activities. Although it yields high participation rates, it should be limited to completely innocuous research (typically not involving minors). It is acceptable for participant observation (ethnographic) projects.
