Screening and Assessment Procedures. Families that are interested will have the research study explained to them, and will be asked to sign an informed consent that explains the study. Research assessors will be trained to conduct the initial screening using the Diagnostic Interview Schedule for Children (DISC) and the Family Environment Scale - Conflict Scale. All participants included in the study will complete a Baseline assessment and will be randomized after testing. Assessments will be conducted again at post-treatment (T2- 4 months), follow-up 1 (T3- 12 months post baseline) and follow-up 2 (T4- 20 months post baseline). A trained Master's-level research assistant who is bilingual in English and Spanish will administer all assessments. Our assessors have worked on multiple projects using the self-reports and interview measures proposed in this study. All measures and consents will be available in Spanish to ensure that primarily Spanish-speaking adolescents or parents are not excluded.
