Impact of a Trauma-Informed Intervention for Youth and Staff on Rates of Violence in Juvenile Detention Settings

Abstract

The majority of youth in the juvenile justice system have experienced multiple traumatic events in their lives, including community violence, physical abuse, neglect, and traumatic loss. These high prevalence rates, coupled with the known negative consequences of trauma in childhood and adolescence, have led to a greater emphasis on implementing trauma-informed services and practices within juvenile justice settings. However, although many stakeholders and government entities have expressed support for creating more trauma-informed juvenile justice systems, there is still limited empirical knowledge about which interventions are most effective at improving outcomes, particularly at the organizational or facility level. In an effort to fill this gap, the current study evaluated the impact of a trauma-informed milieu intervention, including skills training for youth and training for staff, on rates of violence at two secure juvenile detention facilities ( N = 14,856) located in a large Northeastern city. The analyses revealed that the intervention was significantly related to a reduction of violent incidents in Facility A, with no impact on incidents in Facility B. Follow-up analyses revealed that a larger proportion of eligible youth in Facility A completed the skills group program as compared with eligible youth in Facility B (16% vs. 9%). This finding has important implications for the implementation of trauma-informed interventions for youth in juvenile detention settings, as it suggests that to impact outcomes at the facility level, a minimum threshold of youth may need to be exposed to the intervention. In addition, reductions in violence at Facility A were only realized after both staff training and youth skills components were implemented, suggesting that both components are necessary to create change at the facility level. Future research is needed to further explore the impact of organizational and implementation-level factors on trauma-informed care outcomes in juvenile justice settings.
