We never started the study.

Self-injurious thoughts and behaviors (SITBs) are a serious public health concern, particularly for youth involved in the juvenile justice system (JJS), which the Georgia State Juvenile Justice System (GAJJS) intends to address by the implementation of Dialectical Behavior Therapy (DBT) in its JJS facilities. This proposal aims to support and study the GAJJS' pilot implementation of DBT at its facilities using a mixed-methods cross-over design involving a three-phase clinical trial assessing the feasibility, acceptability, and preliminary effectiveness of DBT-A adapted for youth in the GAJJS. By the end of the proposed project, the investigators will have (1) established a research team to continue researching SITB interventions in the GAJJS, (2) developed protocols for implementing and evaluating DBT-A adapted for the JJS delivered in person and via telehealth, and (3) preliminary data on the feasibility, acceptability, and effectiveness of DBT-A adapted for the JJS.

Self-injurious thoughts and behaviors (SITBs) are a serious public health concern across the United States, and youth involved in the juvenile justice system (JJS) are at particularly high-risk for SITBs. As part of the Georgia State Juvenile Justice System (GAJJS)'s decades long collaboration with researchers to reduce the rates of suicide and non-suicidal self-injury (NSSI) among youth under their care, they identified Dialectical Behavior Therapy (DBT) as an ideal intervention to fit their needs and subsequently made plans to pilot an adapted DBT for JJS in a portion of their facilities. DBT is an evidence-based treatment for individuals with complex clinical presentations, which has demonstrated effectiveness at reducing SITBs when adapted for adolescents (DBT-A). Despite its adoption by several JJSs, the effectiveness of DBT-A has yet to be empirically evaluated. A controlled evaluation of DBT-A in JJS is desperately needed to develop a framework for implementation and assess its feasibility, acceptability, and preliminary effectiveness. However, GAJJS does not have the resources or expertise to evaluate the intervention's feasibility, acceptability, and preliminary effectiveness on their own. Therefore, this project proposes to capitalize on this unique opportunity to investigate the GAJJS's implementation of DBT across eight pilot facilities. The investigators propose a mixed-methods cross-over design involving a three-phase clinical trial aimed at assessing the feasibility, acceptability, and preliminary effectiveness of DBT-A adapted for youth in the GAJJS. SITB-related outcomes and DBT-A's feasibility and acceptability will be assessed across two different levels of care (i.e., at short- vs. long-term facilities) and service delivery methods (i.e., in-person vs. telehealth). The project will use feedback from stakeholders, collected at multiple timepoints, to design and iterate the adapted DBT-A program to maximize its feasibility, acceptability, and effectiveness in the GAJJS. The clinical trial will use administrative clinical, health, and educational data of JJS-involved youth to assess how effective DBT-A is at reducing self-harming behaviors and associated risk factors (i.e., deficits in distress tolerance, emotion dysregulation, and interpersonal skills). By the end of the proposed project, the investigators will have (1) established a research team to continue researching SITB interventions in the GAJJS; (2) developed protocols for implementing and evaluating DBT-A adapted for the JJS delivered in person and via telehealth; and (3) preliminary data on the feasibility, acceptability, and effectiveness of DBT-A adapted for the JJS. The investigators will then have the personnel, intervention, and preliminary data to submit an R01 to evaluate the effectiveness of our JJS-adapted DBT-A in a fully powered randomized controlled trial.
