In a four-wave longitudinal study with N = 1,321 adolescents in Germany, we examined the impact of class-level normative beliefs about aggression on aggressive norms and behavior at the individual level over the course of 3 years. 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.
在一项针对德国1321名青少年的四波纵向研究中，我们考察了班级层面关于攻击行为的规范信念在3年时间里对个体层面的攻击规范和行为的影响。在每一波数据收集时，参与者表明他们对攻击行为的规范接受程度，并提供身体攻击和关系攻击的自我报告。多层次分析显示，T1时班级层面和个体层面的规范信念之间在T2时身体攻击的个体差异上存在显著的跨层次交互作用，并且这种间接交互作用在T4时仍然显著。班级层面上对攻击行为的规范认可，尤其是女孩的规范信念，界定了青少年在攻击规范上个体差异的表达及其对身体攻击和关系攻击行为影响的边界条件。研究结果表明社会规范对青少年从个体规范信念到攻击行为的路径具有调节作用。
