<p>One of the key challenges for enhancing the effectiveness of intervention programs for intimate partner violence (IPV) perpetrators is tailoring interventions to participants’ specific risks and needs. A history of childhood or adolescent exposure to family violence as either a direct victim or witness has been consistently associated with an increased risk of IPV perpetration in adulthood. This study examined differences between 1,126 court-mandated male IPV perpetrators with and without a history of family violence exposure during childhood or adolescence across sociodemographic, individual, social-relational, attitudinal, and violence-related variables. The study also examined whether trauma history was associated with IPV recidivism risk beyond sociodemographic characteristics and after accounting for individual, social-relational, and attitudinal factors. Compared to perpetrators without trauma exposure, those with a trauma history were younger, had lower educational attainment, included a higher proportion of immigrant participants, and reported higher impulsivity, anger, depressive symptoms, alexithymia, and substance use. They also reported more stressful life events, lower perceived family and friend support, and higher hostile sexism and victim-blaming attitudes. In addition, they reported greater physical and psychological IPV, a more advanced stage of change, and higher risk of IPV recidivism at intake. Hierarchical logistic regression analyses showed that younger age, unemployment, higher impulsivity, and lower perceived family social support were the variables most strongly associated with trauma history. Hierarchical linear regression analyses further revealed that trauma history remained significantly associated with IPV recidivism risk after accounting for covariates. These findings underscore the importance of incorporating trauma-informed strategies into IPV perpetrator interventions.</p>
