RESUMO
PROBLEM: Sleep and mood represent two important malleable opportunities for adolescent health. This study investigated the sleep-mood relationship in adolescent girls. METHODS: Short-term, longitudinal design. Latina adolescents (N = 19, mean age 15) completed ecological momentary assessments on sleep (perceived quality, self-report quantity) and mood (negative affect, positive affect, and positivity ratio). FINDINGS: Adolescents sent 1,598 texts on sleep and mood. Bidirectional sleep-mood relationships were in expected directions; negative affect and the positivity ratio affect predicted adolescents' sleep quality. CONCLUSIONS: Interventions should encourage sleep-mood relationship awareness, and further research should identify significant differences to inform tailored interventions with adolescents.
