 Emotional disorders, including an array of anxiety and depressive syndromes, are the most common psychiatric disorders among adolescents, are highly comorbid, and severely impair the lives of youth and their families. Extant evidence-based therapies target only single disorders or symptom domains, are often not adopted by community mental health center CMHC clinicians, and have only modest effect sizes. To improve the clinical outcomes of these youth, the proposed study tests the effectiveness of two novel interventions a transdiagnostic intervention, the Unified Protocol for the Treatment of Emotional Disorders in Adolescents, and a measurement and feedback system, the Youth Outcomes Questionnaires relative to usual care in CMHCs.
