In a rural school district with some of the highest rates of bullying in the state, the Aggressors, Victims, and Bystanders: Thinking and Acting to Prevent Violence classroom-based program (AVB) was implemented in an afterschool program setting and delivered using community-based personnel because of lack of time and staffing in the regular school day schedule. High-risk middle school student participants enrolled in an afterschool program for academic support completed the Pre-Post AVB Survey instrument before the first lesson of the 12-lesson AVB curriculum and immediately following the last lesson of the curriculum. Participants' significantly increased their overall confidence that they could prevent violence in their school and lives, significantly decreased their beliefs that support violence, and significantly decreased their behaviors supportive of violence (p .001). Although the program was developed to be implemented as a school-based intervention, in urban areas, and taught by school personnel; this study has provided data to suggest that it may also be effective in the rural, afterschool setting and taught by non-school personnel.
