Falling between two systems of care: Engaging families, behavioral health and the justice systems to increase uptake of substance use treatment in youth on probation.

Justice-involved youth (JIY) in the US have high rates of substance use (SU) problems, yet 50%-80% of these youth do not receive necessary services. There has been no systematic exploration of the use of treatment services for JIY that examines viewpoints across stakeholders in justice- and treatment-systems as well as the families. We conducted qualitative interviews and focus groups with n = 58, youth, their caregivers, SU treatment providers and probation officers in a Northeastern state. Interviews explored how families, staff- and system-level factors influence uptake of and retention in SU treatment services in youth on probation. We conducted a thematic analysis of all interview texts. Caregiver engagement is essential for youth treatment uptake and retention. Difficulties achieving caregiver engagement and agreement that treatment was necessary stemmed from distrust in the "system"; denial or minimization of youth's SU problem; relational barriers; and overburden and chaos within the family system. Structural barriers to service uptake were lack of available treatment options, SU agency practices and policies, and interagency collaboration between SU treatment agencies and probation. Enhancing family engagement at the point of referral to SU treatment is essential. Improvements in interagency collaboration and communication between SU treatment and probation agencies are necessary. Implications for policy and intervention are discussed.
