Association between attitudes toward violence and violent behavior in the school context: A systematic review and correlational meta-analysis.

Background/objective: Both theoretical proposals and empirical work point to a common concurrence between attitudes toward school violence and violent behavior. Studies often address this issue superficially or within intervention programs. Our objective is to describe the results of a systematic review and to conduct a meta-analysis exploring these associations.

Method: A systematic review was conducted in the main databases. Effect sizes were calculated and synthesized using random-effects meta-analysis to estimate the relationship between attitudes toward violence and school violence. A meta-regression was performed for the moderator analysis of sex and age.

Results: The literature search strategy produced 12,293 articles. The review process produced a final result of 23 studies. Our results estimate a significant positive relationship ( =.368 < .001; 95% [.323, .412]) between attitudes toward violence and school violence in children and adolescents.

Conclusions: This study allows us to quantify with an adequate degree of specificity the attitude-behavior relationship in the school context. These results may facilitate future researchers to design programs that address this specificity in order to improve school climate. More research is needed using validated instruments to further specify the type of attitudes that have the greatest influence on the manifestation of school violence.
