This blog post, titled “School‑Based Anti‑Bullying Interventions Work!” and published on September 12, 2022, highlights findings from a comprehensive systematic review and meta‑analysis of 69 studies, underscoring the effectiveness of school-based anti‑bullying programs in reducing both in-person and cyberbullying, as well as improving students’ mental health. These interventions typically include group education sessions for students to foster empathy and anti-bullying attitudes, along with training for school staff to identify and respond effectively to bullying incidents. The results show significant reductions in bullying perpetration and victimization, and notable improvements in anxiety, depression, and overall well-being among students. Endorsed by the Community Preventive Services Task Force and backed by CDC experts, the post offers actionable guidance and resources for educators and administrators seeking to implement evidence-based, school-wide prevention strategies.
