Evidence suggests that cyberbullying among school-age children is related to problem behaviors and other adverse school performance constructs. As a result, numerous school-based programs have been developed and implemented to decrease cyberbullying perpetration and victimization. Given the extensive literature and variation in program effectiveness, we conducted a comprehensive systematic review and meta-analysis of programs to decrease cyberbullying perpetration and victimization. Our review included published and unpublished literature, utilized modern, transparent, and reproducible methods, and examined confirmatory and exploratory moderating factors. A total of 50 studies and 320 effect sizes spanning 45,371 participants met the review protocol criteria. Results indicated that programs significantly reduced cyberbullying perpetration (g = -0.18, SE = 0.05, 95% CI [-0.28, -0.09]) and victimization (g = -0.13, SE = 0.04, 95% CI [-0.21, -0.05]). Moderator analyses, however, yielded only a few statistically significant findings. We interpret these findings and provide implications for future cyberbullying prevention policy and practice.

Students with disabilities (SWDs) are disproportionately at-risk for bullying victimization and perpetration, yet there is a lack of educator-focused professional development targeting prevention for these students. This project sought to address gaps in training through the creation of four online professional development modules: (1) understanding bullying among SWDs, (2) examining risk characteristics, (3) establishing school and classroom prevention strategies, and (4) individual prevention. These modules were iteratively developed with feedback from teachers and staff, incorporating the Multi-Tiered System of Supports (MTSS) framework to focus on interventions rooted in social emotional learning (SEL), and emphasizing the importance of prevention for SWDs.
