Background:
How the Study Was Conducted:
Results: Studies indicate that bullies, victims and bully-victims were more likely to carry weapons. Studies conducted in the U.S. found stronger associations between being a bully-victim and weapon-carrying than studies in other countries.
Conclusion: "The current meta-analysis suggests that bullying is related to weapon carrying among adolescents and further establishes bullying as a risk factor for adolescent problem behavior. Given the wide range of negative implications bullying may have, it is important that schools endeavor to reduce bullying among their students, preferably by using evidence-based methods."
