Findings 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.

Youth justice services around the world are under increasing pressure to find new and more effective ways of working with young people. One way forward is to implement a more compassionate approach to service delivery that embraces the idea of ‘trauma-informed practice’. And yet, substantial variation has been observed in how a trauma-informed approach has been defined and understood by practitioners, with idiosyncratic implementation evident across different systems and only limited evidence that this results in reductions in subsequent re-offending. In this paper we argue that the success of efforts to work in more trauma-informed ways cannot be judged using recidivism data alone and that there is a need to identify key indicators of the effectiveness of any trauma- informed approach. We present the case for implementing trauma-informed youth justice and outline key features of the approach. We then present a logic model that articulates key components and identifies short- and longer-term outcomes that can be measured to assess the overall performance of a service. The article concludes with a discussion of the current evidential status of trauma-informed youth justice, identifying areas of current strength and those where further work is needed to develop the evidence base, including the need to demonstrate the hypothesized association between short-term trauma-informed practice outcomes and the longer-term goal of preventing re-offending.
