A bullying intervention system in high school: A two-year school-wide follow-up

This study is an evaluation of a systemic, two-year, whole-school bullying intervention initiative that was implemented in a US public high school. Students and staff members were anonymously surveyed before and after the intervention. The goals of the initiative were to reduce bullying and victimization, increase disclosure, increase intervention efforts, and reduce student aggression. Except for a reduction in victimization, all goals were achieved in some measure. Self-reported bullying decreased 50% or more. Students’ reporting that peers intervened in bullying increased. Staff-reported reductions in student aggression, and staff's belief that the school's efforts to address bullying were adequate increased. This evaluation points to the possible success of a whole-school, systemic approach to managing bullying at the high school level.
