Early Adversity and Sexual Risk in Adolescence: Externalizing Behaviors as a Mediator.

Sexual risk behavior in adolescence can result in serious health consequences that persist across the lifespan, particularly for female youth. While adverse childhood experiences (ACEs) are linked to engagement in sexual risk behavior later in life, little research has examined pathways that may help explain this association. To address this gap, the present study examined whether internalizing and externalizing behaviors mediated the link between (ACEs) and sexual risk behavior in female youth. We examined data from 122 adolescent girls, ages 13-18, who were involved in the juvenile justice system or receiving social supports from local agencies and schools. Girls were asked to report their exposure to ACEs and engagement in sexual risk behavior and caregivers were asked to report on girls' internalizing and externalizing behaviors. Regression analyses indicated that girls who experienced more ACEs and exhibited more externalizing behaviors demonstrated higher rates of sexual risk. Further, externalizing behaviors partially mediated the association between ACEs and sexual risk behavior. Findings suggest that increased exposure to ACEs and higher incidence of externalizing behaviors may place girls at heightened risk for sexual risk behavior. Interventions aimed at decreasing externalizing behaviors may be particularly important in reducing sexual risk behavior among at-risk female youth.
