  abstract  = {Several longitudinal studies and meta-analytic reviews have demonstrated that exposure to violent media is linked to aggression over time. However, evidence on effective interventions to reduce the use of violent media and promote critical viewing skills is limited. The current study examined the efficacy of an intervention designed to reduce the use of media violence and aggression in adolescence, covering a total period of about 12 months. A sample of 683 7th and 8th graders in Germany (50.1\% girls) were assigned to two conditions: a 5-week intervention and a no-intervention control group. Measures of exposure to media violence and aggressive behavior were obtained about 3 months prior to the intervention (T1) and about 7 months post-intervention (T2). The intervention group showed a significantly larger decrease in the use of violent media from T1 to T2 than the control group. Participants in the intervention group also scored significantly lower on self-reported aggressive behavior (physical aggression and relational aggression) at T2 than those in the control group, but the effect was limited to those with high levels of initial aggression. This effect was mediated by an intervention-induced decrease in the normative acceptance of aggression. No gender differences in program efficacy were found. The results show that a 5-week school-based intervention can produce changes in the use of media violence, aggressive norms, and behaviors sustained over several months.},

  abstract  = {The relations between adolescents' habitual usage of media violence and their tendency to engage in aggressive and prosocial behavior in a school setting were examined in a cross-sectional study with 1688 7th and 8th graders in Germany who completed measures of violent media exposure and normative acceptance of aggression. For each participant, ratings of prosocial and aggressive behavior were obtained from their class teacher. Media violence exposure was a unique predictor of teacher-rated aggression even when relevant covariates were considered, and it predicted prosocial behavior over and above gender. Path analyses confirmed a direct positive link from media violence usage to teacher-rated aggression for girls and boys, but no direct negative link to prosocial behavior was found. Indirect pathways were identified to higher aggressive and lower prosocial behavior via the acceptance of aggression as normative. Although there were significant gender differences in media violence exposure, aggression, and prosocial behavior, similar path models were identified for boys and girls.},
