Triple Vulnerability? Circadian Tendency, Sleep Deprivation and Adolescence
Abstract
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.
Conditions: Eveningness/Sleep.
Primary outcome: Total Sleep Time (TST) Average on Weeknights Via Daily Sleep Diary; Average Bedtime on Weeknights Measured Via Daily Sleep Diary; Morning Eveningness Preference Measured Via Childrens Morningness Eveningness Preference Scale; Composite Score for Cognitive Domain; Composite Score for Behavioral Domain; Composite Score for Emotional Domain; Composite Score for Social Domain; Composite Score for Physical Domain.
Enrollment: 176 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 176 participants or records.
