Juvenile probation officers (JPOs) are increasingly using risk/needs assessments to evaluate delinquency risk, identify criminogenic needs and specific responsivity factors, and use this information in case planning. Justice-involved youth are exposed to traumatic events and experience traumatic stress symptoms at a high rate; such information warrants attention during the case planning process. The extent to which JPOs identify specific responsivity factors, in general, and trauma history, specifically, when scoring risk/need assessments is understudied. In the current study, 147 JPOs reviewed case vignettes that varied by the adolescents' gender (male vs. female), traumatic event exposure (present vs. absent), and traumatic stress symptoms (present vs. absent), and then scored the YLS/CMI and developed case plans based on that information. JPOs who received a vignette that included trauma information identified a higher number of trauma-specific responsivity factors on the YLS/CMI. Despite an overall high needs match ratio (57.2%), few JPOs prioritized trauma as a target on case plans. The findings underscore the importance of incorporating trauma screening into risk/needs assessment and case planning. (PsycINFO Database Record
