Youth Violence and Juvenile Justice, Ahead of Print.
BackgroundYouth involved with the justice system are more vulnerable to trauma exposure and engaging in violent behavior. Trauma exposure is linked to increases in youth violence, however, the pathway from trauma to violence, including neurocognitive and neuropsychological mechanisms, is not well understood. The current study sought to test the influence of hostile attribution bias (HAB) and working memory on violence and whether these factors play a role in the link between trauma and violence among justice-involved youth.MethodsParticipants included 237 detained youth (Male = 81.0%, Mage = 15.22) who completed self-report surveys and working memory tasks.ResultsTrauma was significantly associated with violent behavior. HAB was related to physical violence; however, when trauma exposure was entered into subsequent models, HAB was no longer associated with violence. Lower levels of working memory were found to interact with HAB to increase the risk of physical violence. Mediation was not supported.ImplicationsThe current study supports universal trauma screening and trauma-informed care in justice facilities and suggests that neurocognitive functioning assessment and remediation are important to consider in treatment programming.
