RT Article T1 An Evaluation of a Trauma-Informed Intervention in Secure Juvenile Detention: The Impact on Youth-Level Incidents of Violence JF Criminal justice and behavior VO 52 IS 5 SP 716 OP 733 A1 Baetz, Carly Lyn A1 Surko, Michael A1 Guo, Fei A1 Marr, Mollie A1 Workman, Sara A1 Havens, Jennifer A1 Horwitz, Sarah McCue A2 Surko, Michael A2 Guo, Fei A2 Marr, Mollie A2 Workman, Sara A2 Havens, Jennifer A2 Horwitz, Sarah McCue LA English YR 2025 UL https://krimdok.uni-tuebingen.de/Record/1922897329 AB Few studies have examined the impact of trauma-specific interventions in juvenile justice settings, and juvenile justice-related outcomes are infrequently assessed. This study examined the impact of implementing youth skills groups (Skills Training in Affective and Interpersonal Regulation [STAIR]) and trauma training for staff (Think Trauma) on individual-level assaults in two secure detention facilities. The impact of the intervention was primarily evidenced in one facility among Black youth. In the same facility, the staff training (pre-skills groups) cohort and skills group cohort (post-staff training) evidenced a significantly greater reduction in violent incident rates as compared to the pre-intervention cohort. These findings highlight the importance of trauma-focused training for staff as a promising step toward reducing violence and improving staff members’ responses to a large subset of vulnerable youth.
