A growing body of research has demonstrated consistent links between Bandura's theory of moral disengagement and aggressive behavior in adults. The present meta-analysis was conducted to summarize the existing literature on the relation between moral disengagement and different types of aggressive behavior among school-age children and adolescents. Twenty-seven independent samples with a total of 17,776 participants (aged 8-18 years) were included in the meta-analysis. Results indicated a positive overall effect (r = .28, 95% CI .23, .32), supporting the hypothesis that moral disengagement is a significant correlate of aggressive behavior among children and youth. Analyses of a priori moderators revealed that effect sizes were larger for adolescents as compared to children, for studies that used a revised version of the original Bandura scale, and for studies with shared method variance. Effect sizes did not vary as a function of type of aggressive behavior, gender, or publication status. Results are discussed within the extant literature on moral disengagement and future directions are proposed.
