Abstract
This study, rooted in the Bioecological Systems and Cultural Spillover theories, explores the factors influencing interpersonal violence development. Analyzing data from 4,167 men (mean age = 20.67, SD = 1.71) and 9,969 women (mean age = 20.42, SD = 1.70), the model tests the influence of sex, childhood aggression, self-control, violent peers, violent parenting, violence approval, state violence, and militarization on interpersonal violence. Linear Mixed-Effects Models revealed that interpersonal violence is positively associated with childhood aggression, violent peers, violent parenting, and violence approval; and it is negatively associated with self-control. State violence and militarization indirectly affect interpersonal violence through violent parenting and violence approval. The findings underscore the complex interplay of individual and societal factors in shaping interpersonal violence.
