This study examined the prospective association between peer victimization and subjective sleep quality among typically developing early adolescents. At Time 1 (T1), participants included 123 youth (50% boys; X-bar age = 12.03 years; 58.5% European American, 35% African American), along with one parent and teacher. Youth, parents, and teachers reported on youth's experiences of peer victimization at T1. Youth reported on sleep quality at T1 and T2 (10 months later). Results from regression analyses revealed that youth-reported, but not parent- or teacher-reported, peer victimization predicted poorer sleep quality over time. Findings provide evidence that experiences of peer victimization can have a negative impact on youth's sleep quality over time.
