IntroductionSchool violence is a ubiquitous cause of distress for parents, teachers and administrators. The high rates of assaults, threats and physical harm in schools have not only been studied by researchers, but have also been regularly covered by the media and have therefore drawn further public attention to the problem. “According to the National Center for Education Statistics (NCES), results from the School Crime and Safety Survey indicated that approximately 76 percent of schools reported violent incidents for the 2007-2008 school year….65 percent of primary schools, 94% of middle schools and 94% of high schools…. Physical fights have been noted as the most common form of violence in school settings” (as cited in Fahsl & Luce, 2012, p.214). Opinion polls “rank school discipline as a major concern in U.S. public schools” (Fahsl & Luce, 2012). Therefore, finding answers about how to prevent and reduce aggressive behavior against students in order to protect children and youth from being bullied, threatened and victimized in schools is a primary concern for parents, teachers, administrators and policy makers. Bliss, Emshoff, Buck, and Cook (2006) reported that “parents showed strong support for nearly all proposed causes and solutions” and the authors addressed “parents' desire for immediate and often invasive interventions to prevent future violence " (p. 265). Numerous studies have examined the effect of violence prevention programs to determine whether these programs reduce hostile behavior and serve to protect students and teachers from aggressors' aggression. Most studies have focused on the outcomes of these programs on attached students, but there appear to be no studies that...... half of the article ......mention the programs, from different theories of behavior change to social learning theory or providing information on predictors of violence and how to avoid them. Hahn et al. used a conceptual model and analytical framework to evaluate the effectiveness of violence prevention programs in reducing violence (Figure 1). The authors' flowchart illustrates the influences of the intervention on the outcome categories. Considering the positive outcome of researchers who have studied the effect of violence prevention programs on violence reduction, both by conducting a study and by reviewing studies, I argue that my study, analyzing the effect of violence prevention programs on number of attacks against teachers, will contribute to the thematic academic literature by providing a better understanding of violence prevention programs and their effect on violent behavior.
