Adolescents screened for symptoms of substance abuse/dependence, and their families, will participate in the study. Participants will include 260 male and female adolescents who complete the enrollment process, meet eligibility criteria, and consent to be randomized into one of two study conditions. Youth will be referred primarily from two sources: juvenile justice agencies and local schools/community programs. Based on the demographics of adolescents currently participating in partner sites, youth are likely to be predominantly male (69%), Hispanic (68%), and African American (32%). Families are generally low income from disadvantaged neighborhoods, with high rates of family mental health and substance use problems.
