Mental health and/or substance use (MHS) challenges affect approximately 95% of youth in the criminal justice system, with only three in ten justice-involved youth receiving treatment. Caregivers of justice-involved youth have identified fragmented care as a barrier to youth accessing MHS services. One suggested solution to this problem is the implementation of integrated youth services (IYS). However, it is unknown which IYS components caregivers of justice-involved youth prioritize. Using a discrete choice conjoint experiment (DCE), n = 46 caregivers of justice-involved youth, and n = 204 caregivers of non-justice-involved, completed thirteen choice tasks representing different combinations of IYS. Both caregiver groups exhibited preferences for involvement and access to information regarding their youth's treatment, and fast access to broad range of core health and additional services, in a community setting, with the incorporation of e-health services. Caregivers of justice-involved youth showed a unique preference for involvement in family counseling with their youth. The incorporation of this service feature may help to engage caregivers of justice-involved youth in their youths' MHS treatment 3-fold. Data gleaned from this analysis provides an understanding of what components of IYS models may help to engage caregivers of justice-involved youth.
