Honor refers to socially conferred self-worth, strong norms of reciprocity, and direct retaliation for transgressions. Honor norms have been discussed as relevant in explaining aggressive behavior, particularly for immigrant groups. In this study we examined the endorsement of honor norms and their association with aggressive behavior in a culturally diverse sample in Germany. Online questionnaire data were used from male adolescents aged 11-18 years (N= 774; M[subscript age] = 15.37, 34.2% with a migration background). Multiple linear regression analyses indicated that students of Turkish and Russian origin endorsed honor more than students without a migration background, whereas students of Polish origin did not differ. Within negative binomial regression models, honor endorsement was significantly positively related to aggressive behavior, while this effect did not differ between students from different migration backgrounds and students without migration background respectively. Thus, the internalization of honor norms emerged as a general risk for aggressive behavior among male adolescents.
