Predicting Antisocial Personality Features among Justice-Involved Males and Females: The Effects of Violence Exposure in Childhood and Adolescence

Abstract

The high rate of antisocial personality disorder (ASPD) among individuals involved in the justice system represents a significant public health concern, as individuals with ASPD are more likely to reoffend after incarceration and to engage in longer-term offending behavior patterns over the lifespan. Research suggests that traumatic event exposure in childhood and adolescence may be one factor that contributes to the heightened risk for ASPD in adulthood, though findings are mixed depending on the operationalization of trauma exposure and demographics of study samples. The present study examined the impact of early and varied exposure to violence on the development of ASPD features in young adulthood. In addition, given evidence for gender differences in how youth respond to trauma, as well as disparate prevalence rates of ASPD among males and females, a secondary aim was to assess the impact of gender on the relationship between early trauma and antisocial personality outcomes. The study sample consisted of 1354 adolescents (86% male) who participated in a longitudinal research study of serious juvenile offenders. A series of linear regression analyses revealed that the magnitude of violence exposure participants endorsed at baseline significantly predicted antisocial personality features at six-year follow-up. Participants’ gender was not found to moderate the relationship between violence exposure and antisocial outcomes. Results suggest that targeting maladaptive cognitions and behaviors resulting from chronic exposure to early trauma may be a crucial component of treatment for justice-involved individuals exhibiting ASPD features.
