Released/updated on: 2025-03-13
Geographic coverage: United States
Time period: 2011-02-01--2018-06-30
This NIJ-funded project extended an evaluation of the Olweus Bullying Prevention Program (OBPP) conducted as part of a project funded by the Centers for Disease Control and Prevention (CDC). The OBPP is a comprehensive school-based program designed to prevent youth violence and bullying by improving school climate. The CDC-funded project used a multiple baseline experimental design that randomized the order and timing of implementing the OBPP in three urban public middle schools in the southeastern United States over a five-year period from 2010-2015. The project collected outcome data from random samples of students at the three participating middle schools on their frequency of aggression and victimization, peer factors related to aggression, and school climate variables every three months, and obtained ratings of student's frequency of aggression and victimization from teachers. The NIJ-funded project extended the CDC-funded project by continuing the implementation of OBPP in schools that were already receiving the program, implementing OBPP in the remaining school that served as the control school for the Virginia Commonwealth University - Violence Prevention Project (VCU-VPP), and collecting an additional 10 waves of data from 2015 to 2018. The dataset included in this study includes data from both the CDC and NIJ-funded projects across 29 waves of data collection from 2011 to 2018.
