Sleep and Adjustment in Adolescence: A Longitudinal, Person-Centered Approach

This study utilized latent profile analysis to investigate heterogeneity in adolescent sleep patterns and their prospective links with depression, alcohol use, and cannabis use. Three sleep profiles were identified (e.g., healthy, low-quantity/later bedtime, low-quality). Low-quantity and low-quality sleepers were at increased risk for depression and substance use one year later.
