Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
There is an urgent need to identify modifiable mechanisms contributing to risk and vulnerability among youth. The investigators test the hypothesis that eveningness, the tendency to go to sleep late and wake late, is an important contributor to, and even cause of, vicious cycles that escalate vulnerability and risk among youth. This study seeks to determine whether two interventions to reduce eveningness can reduce risk and confer resilience in critical aspects of health, development and functioning in youth.
