Because of its connection to violent and aggressive behavior that can result in serious injuries to victims and others, bullying is now considered a major public health issue. Suicides and murders (often by bullying victims) have been linked to bullying; school shootings have been perpetrated by bullying victims. Males and females tend to differ in their bullying styles. Girls are more likely to engage in psychological and verbal bullying; whereas, boys are more likely to bully through physical attacks. Bullying is reinforced by peers who act as audiences for and supporters of the bullying behavior. Research studies suggest that bullying has negative short-term and long-term consequences for all involved. Of particular concern is the link between bullying behavior and future violence. Both the bullying of others and being bullied have been consistently linked to violent behaviors for both boys and girls. A critical component of effective antibullying interventions is encouraging victims to tell someone about the abuse, so appropriate intervention can occur. The most effective interventions have involved a schoolwide policy that defines unacceptable behavior and sets strategies for addressing it. Effective strategies are to have teachers and pupils develop positive social relationships through cooperative group work. Other methods include allotting time for students to address relationship issues, asking circles of friends to support a vulnerable student, creating conflict resolution activities, and using teacher mediation. Most States have enacted laws to define and deter bullying. 29 references
