Evaluation of the Effectiveness and Sustainability of the Olweus Bullying Prevention Program (OBPP) in Increasing School Safety for Urban Low-Income Middle Schools, Virginia, 2011-2018

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.
