Adverse childhood experiences (ACEs) have been linked to a host of negative health and behavioral outcomes, including crime, delinquency, and violence. Recent work on ACEs suggests that the impact of ACEs differs by gender, but research is unclear on the mechanisms of this relationship and how they impact violent delinquency. To explore whether and how the impact of ACEs on violent delinquency varies by gender, this study draws on Broidy and Agnew’s gendered expansion of general strain theory (GST), which proposes that a key explanation for the gendered impact of strain on crime lies in gender differences in the negative emotional states that mediate the relationship. Using longitudinal data on a sample of 979 at-risk youth (558 girls and 421 boys) from the Longitudinal Studies on Child Abuse and Neglect, this study examines the impact of ACEs (sexual abuse, physical abuse, emotional abuse, physical neglect, supervisory neglect, parent mental illness, parent intimate partner violence, parent substance use, parent criminality, and family trauma) on violent delinquency by gender with consideration of the three negative emotional states hypothesized by GST—anger, depression, and anxiety. Results indicate that ACEs increase the odds of violent delinquency for both boys and girls, but that this relationship is significantly stronger for boys. Mediation models suggest that anger mediates the link between ACEs and violent delinquency for girls. Implications for research and policy centering on ACEs are discussed.
