Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS) National Survey was funded in part to describe the current status of screening, assessment, prevention and treatment for substance use, mental health, and HIV for youth on community supervision within the US juvenile justice system. Surveys were administered to community supervision agencies and their primary behavioral healthcare providers, as well as the juvenile or family court judge with the largest caseload of youth on community supervision. This article presents the findings from the judges’ survey. Survey results indicated juvenile and family court judges were open to innovations for improving the court’s performance, rated their relationships with collaborators highly, and appreciated the impact of screening, assessment, prevention, and treatment on judicial practices.
