Aggressive and Violent Behaviors in the School Environment Among a Nationally Representative Sample of Adolescent Youth.

ABSTRACT BACKGROUND The purpose of this study was to describe the prevalence of aggressive and violent behaviors in the context of the school environment in a nationally representative sample of adolescent youth and to illustrate these patterns during 2001-2011. METHODS We analyzed data from 84,734 participants via the Youth Risk Behavior Surveillance System ( YRBSS). Frequencies were visualized using heatmaps. One-way analyses of variance and corresponding post hoc tests helped to identify if differences in prevalence fluctuated significantly across all years. RESULTS Rates of youth feeling unsafe in their school environment, bringing weapons to school, and engaging in physical fighting on school property continue to persist. Findings illustrated that Hispanic youth and youth classified as 'other' have emerged as particularly high-risk demographic subgroups over the past decade. Peer victimization and sexual victimization continue to affect girls disproportionately. CONCLUSIONS Though some variation within demographic subgroups exists, rates of aggressive and violent behaviors in the context of the school environment continue to persist. Implications for the coordinated prevention of aggressive and violent behaviors among adolescent youth are discussed and recommendations for school-based prevention efforts are identified.
