Informed consent in school health research: why, how, and making it easy.

The obligation to obtain informed consent for student participation in health-related research creates a complex set of legal, ethical, and administrative responsibilities because the interests of research integrity are delicately balanced against protection of human subjects. Even the term itself sparks a range of responses depending on one's perspective and stake in the process. This paper traces the historical impetus behind obtaining informed consent, identifies key elements comprising informed consent, and reviews types of consent procedures used in schools. The authors suggest 20 ways to boost response rates while providing a realistic level of informed consent for school-based studies.
