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.
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.
To guarantee that participants understand what they are consenting to, researchers should pay attention to the language they use. They should use the language that their target population will be most comfortable with. As a rule, they should refrain from using technical language and use an 8thgrade level of English. Depending on the methodology you are using, the population and topic you are studying, and the level of risk, informed consent may be implied or explicit, active or passive, and written or oral.
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.
