Juvenile Justice-Translating Research Interventions for Adolescents in the Legal System (JJ-TRIALS; a cooperative implementation science initiative launched by NIDA in July 2013) seeks to reduce unmet substance use disorder (SUD) needs by assisting JJ agencies in their efforts to implement best practices and improve SUD service utilization along a behavioral health cascade (screening, assessment, referral, and treatment). Such efforts require systems-level change; thus, the JJ-TRIALS study targets JJ agencies and the behavioral health partners to which juveniles are referred (i.e., providers of SUD services).
Aaron’s implementation science framework  provides the foundation for study design and measurement. EPIS conceptualizes change processes as involving four phases: Exploration, Preparation, Implementation, and Sustainment (EPIS). The development of the implementation intervention components, the timing of components, and the measurement of process improvement activities are guided by Aarons’ EPIS model. For instance, data-driven decisionmaking (DDDM) templates and tools will provide basic support for goal selection during the Exploration phase. EPIS also has implications for measurement of process improvement activities. While the four phases are presented linearly, improvement activities may be somewhat recursive, with sites revisiting earlier phases when modifications in their action plans are needed (e.g., reworking Preparation plans after initial Implementation).
Using a clustered randomized design, JJ-TRIALS will compare two implementation interventions: a Core Intervention, involving DDDM strategies to promote change across the EPIS phases, versus an Enhanced Intervention, providing support for DDDM through facilitation and inter-agency change teams. A total of 36 sites representing 7 states and the District of Columbia will be randomized to Core (n = 18) or Enhanced (n = 18) and to one of three start times. Primary research questions address whether DDDM strategies and facilitation of DDDM tools/implementation teams improve: a) the provision and quality of services along a behavioral health cascade (screening, assessment, referral, and treatment of youth with SUD); and b) attitudes toward/use of best practices among staff working with justice-involved youth. Exploratory research questions focus on aspects of the implementation process, inter-organizational collaboration, costs associated with each study arm, and youth outcomes.
The authors would like to acknowledge the contributions of JJ-TRIALS Juvenile Justice Partners for their efforts in developing all aspects of the study protocol. This work was supported by the National Institute on Drug Abuse.
