A1 - Krahé, Barbara T1 - Assessing anger regulation in middle childhood BT - development and validation of a behavioral observation measure T2 - Postprints der Universität Potsdam : Humanwissenschaftliche Reihe N2 - An observational measure of anger regulation in middle childhood was developed that facilitated the in situ assessment of five maladaptive regulation strategies in response to an anger-eliciting task. 599 children aged 6-10 years (M = 8.12, SD = 0.92) participated in the study. Construct validity of the measure was examined through correlations with parent- and self-reports of anger regulation and anger reactivity. Criterion validity was established through links with teacher-rated aggression and social rejection measured by parent-, teacher-, and self-reports. The observational measure correlated significantly with parent- and self-reports of anger reactivity, whereas it was unrelated to parent- and self-reports of anger regulation. It also made a unique contribution to predicting aggression and social rejection.

The prevalence of sexual aggression was investigated for both males and females from the perspectives of both victims and perpetrators in relation to three coercive strategies, three different victim–perpetrator relationships, and four types of sexual acts. We also examined the extent to which alcohol was consumed in the context of sexually aggressive incidents. The overall self-reported victimization rate was 34.3% for females and 28.4% for males. The overall perpetration rate was 11.7% for males and 6.5% for females. The gender difference was significant only for perpetration. Prevalence rates of both victimization and perpetration were higher for people known to each other than for strangers. In the majority of victimization and perpetration incidents, alcohol was consumed by one or both parties involved. The findings are discussed in relation to the international evidence and the need for tailored risk prevention and reduction programs.

At each data wave, participants indicated their normative acceptance of aggressive behavior and provided self-reports of physical and relational aggression. Multilevel analyses revealed significant cross-level interactions between class-level and individual-level normative beliefs at T1 on individual differences in physical aggression at T2, and the indirect interactive effects were significant up to T4. Normative approval of aggression at the class level, especially girls’ normative beliefs, defined the boundary conditions for the expression of individual differences in aggressive norms and their impact on physically and relationally aggressive behavior for both girls and boys. The findings demonstrate the moderating effect of social norms on the pathways from individual normative beliefs to aggressive behavior in adolescence.
