DESIGN AND METHODS. Overview. The first phase of the proposed study will include minor adaptations to the manual to enhance its "fit" with the specific characteristics of the target population, finalizing all assessment measures, finalizing the list of CTAU agencies and the referral mechanisms, conducting therapist training for the CIFTA conditions and assessor/interviewer training, and strengthening our connections with referral sources (months 1- 5). The team is experienced in all of these activities from previous treatment development and clinical trial projects. Immediately following this phase, the investigators will begin to recruit adolescents (11-14 years of age) who meet DSM-IV criteria for two of the following diagnoses (CD, DD, ADD) OR DSM-IV criteria for one diagnosis (CD, DD, ADD) and severe family conflict. Following screening, consent and assessment, the adolescents and their families will be randomly assigned to either the (1) Community Treatment as Usual Agency, or the (2) Culturally Informed Family Therapy for Adolescents. Assessments will be conducted at baseline (T1), post-treatment (T2- 4 months), follow-up 1 (T3- 12 months post baseline) and follow-up 2 (T4- 20 months post baseline). Data from service utilization and self-reports of therapeutic alliance will also be collected throughout the entire course of therapy. Longitudinal data analysis (growth curve modeling) will be used to test study hypotheses. Each of the specific components and procedures are described in detail below.
