Rates of traditional bullying have remained stable (30%) but rates of cyberbullying are increasing rapidly (46% of youth). There are significant long-term physical and mental health consequences of bullying especially for vulnerable youth. Multi-component school-based prevention programs that include caring adults, positive school climate, and supportive services for involved youth can effectively reduce bullying. While bullying has emerged as a legitimate concern, studies of surviving perpetrators to date suggest bullying is not the most significant risk factor of mass school shootings. Pediatricians play a critical role in identification, intervention, awareness, and advocacy.
