abstract="The daily challenges resulting from all types of school violence-such as physical  aggression, bullying, peer victimization, and general threats-have the potential to  affect, longitudinally, students' mental health, school performance, and involvement  in criminal or delinquent acts. Across primary and secondary studies, however,  variation in how and how much school violence relates to these outcomes, has  persisted. The purpose of this systematic review and meta-analysis, therefore, was  to clarify this uncertainty by synthesizing the longitudinal relations. We conducted  exhaustive searching procedures, implemented rigorous screening and coding  processes, and estimated an underused effect size, the partial correlation from  multiple regression models, before estimating a random-effects meta-analysis using  robust variance estimation. We meta-analyzed 114 independent studies, totaling 765  effect sizes across 95,618 individual participants. The results of the overall  analyses found a statistically significant longitudinal relation between school  violence, in any role, and the aggregated outcome variables (rp =.06). Given that  this effect size inherently controls for multiple potential confounding covariates,  we consider the relation's magnitude clinically meaningful. We end by discussing  ways practitioners and researchers may use these analyses when implementing  prevention programming and how the field of meta-analysis should more frequently  utilize the partial correlation.
