The Outcomes of Trauma-Informed Practice in Youth Justice: An Umbrella Review

Abstract

AbstractFindings of high rates of complex trauma among justice-involved young people have engendered interest in developing trauma-informed youth justice systems. Although there have been several reviews of trauma-informed practice in youth justice settings, uncertainty remains about whether this approach can produce the outcomes expected of youth justice services. In this study we summarize findings from recent systematic reviews and meta-analyses to provide an overview of evidence relevant to implementing trauma-informed youth justice. We conducted an umbrella review of systematic reviews published between 2017 and 2023 that included group-based primary studies of trauma-informed interventions for justice-involved young people. Reviews were located via searches of PsycINFO, PubMedCentral, Embase, Criminal Justice Abstracts with Full Text, and ProQuest. Data extracted from each review included the number and type of primary studies reviewed, and outcomes related to trauma symptomatology, mental health and wellbeing, and justice system involvement. Nine systematic reviews met our inclusion criteria. Improvements in trauma symptoms, mental health and wellbeing, and justice system involvement were documented in each review. The strongest evidence related to the impact of trauma-focused interventions on posttraumatic stress disorder symptoms, but less evidence was available to demonstrate outcomes of organizational level and systemic components of trauma-informed practice. Each review highlighted the need to strengthen the methodological quality of primary studies. Trauma-informed practice should be seriously considered as part of any effort to implement evidence-based youth justice. This should extend beyond treatment of trauma symptomatology to incorporate a broader approach to trauma-informed practice that is organizationally embedded.
