Do you need to obtain consent and/or assent?

Human subjects must provide informed consent to participate in your research. If your study subjects are children (6-18 years of age) assent also must be obtained.

The researcher has a legal and ethical obligation to ensure that prospective study participants have sufficient knowledge and understand all aspects of the research prior to obtaining informed consent. This means the prospective research participant must be able to make an informed decision as to whether or not to participate in research. Valid informed consent should be obtained by using a simple, but complete consent form written at an appropriate educational level for the participant population. As part of the process for obtaining informed consent, each element of consent should be carefully and simply explained to the prospective participant. In addition, the researcher should periodically assess the prospective participant's understanding by asking appropriate questions. The researcher bears full responsibility for obtaining valid informed consent from the participant. 

Investigators should be sensitive to the possible need of an interpreter/translator for participants who do not speak English as a first language or who are hearing impaired.  Follow the Process for Obtaining Informed Consent, and make sure that you have included all of the components required in the consent form.  This link explains each of these components.   

The requirements for informed consent are less rigorous for Exempt reviews and for research that poses “less than minimal risk” as opposed to “minimal risk or greater.”  

Legally, children cannot give consent on their own behalf.  The consent of their parent(s) or legal guardian is required before children can participate in research projects.  In addition to obtaining parental/legal guardian consent, researchers must also obtain assent of children between the ages of 5 and 18.  If a subject is age 5 or younger, consent from a parental/legal guardian is required.
