Implied consent. Participation in the study is proof of consent. This is acceptable for studies that provide anonymity, such as opinion surveys. A statement at the top of the instrument should clearly state that by filling it, the participant consents to participate, but does not wave any of their rights as research participant. Projects using implied consent should use the consent statementtemplate provided in this website, or a similar document, in their proposal. It provides active implied consent.
Free consent forms are offered on this page. More than sixty consent forms are selected for personal use and free download. The large collection of consent forms covers abortion consent forms, interview consent form, drug test consent form and so on, including this questionnaire consent form.
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.
The consent form template below will be suitable for many studies but may need alterations to be commensurate with your study and must be used in conjunction with the guidance given in Information Sheets & Consent Forms.
