The purpose of this was to leverage an existing randomized controlled trial of The Second Step anti-bullying program, which was implemented when the sample of students was in middle school, by measuring related aggressive behaviors (e.g. bullying, cyberbullying, sexual violence) during the high school years. The objectives of this study were to determine treatment effects of the Second Step middle school program on reductions in youth aggression (including bullying), sexual violence, substance use, and teen dating violence when in high school, as well as to assess middle school belonging as a mediator of these treatment effects on targeted problem behaviors in high school. Demographic variables included as part of this collection are students' age, gender, race, and household characteristics. The collection contains 3 SPSS data files:
