A fast growing body of research suggests that sleep may play a role in adolescent school success. The PASS research group in the VCU Clark-Hill Institute was recently funded by the Institute of Education Sciences to conduct what will be one of the largest longitudinal studies of the association between sleep and adolescent academic achievement and social/emotional well-being. We will follow 300 adolescents, 150 with ADHD and 150 without ADHD from 8th grade through 10th grade to carefully evaluate how changes in sleep impact school performance. This study will provide important information that will inform best-practice sleep guidelines for schools and families. If you are interested in learning more about this study or participating, please read the Sleep Study Introduction Letter and the Sleep Study Flyer. You may also call (804) 828-5517. All families and adolescents will be compensated for their time and effort.
