0962 CONCOMITANT AND LONGITUDINAL CHILDHOOD SLEEP CHARACTERISTICS ASSOCIATED WITH EXTERNALIZING PROBLEMS DURING ADOLESCENCE

Abstract Introduction: Sleep problems have been linked to externalizing problems during adolescence. There is limited knowledge as to the temporal childhood sleep characteristics and subsequent adolescent externalizing problems. Our aims were 2-fold: 1) to examine whether sleep characteristics are concomitantly associated with externalizing problems at 15 years and 2) to investigate whether childhood sleep characteristics predicted externalizing problems at 15 years. Methods: Longitudinal data on 1441 children were collected by questionnaires and interviews from 5 months to 15 years (13 waves). At 15 years, sleep characteristics and externalizing problems were completed according to the adolescent’s opinion. Childhood sleep characteristics trajectories (nocturnal sleep duration, nocturnal awakening duration and sleep latency) were completed according to the mother’s opinion (2.5 months to 10 years). Pearson correlations, t-tests and Anovas were performed (p
