This case study illustrates one successful outcome of an intensive, outpatient, treatment project for adolescents with mood disorders. An 18-year-old female with symptoms across several DSM-IV Axis I classifications, including a depressive disorder, and her parents participated in a year-long, multimodal intervention that included mood-focused psychoeducation and coaching designed to impact on her, her family, school, and community systems. Self-report, clinician-driven, and ecologically valid measures were used to assess treatment effects on psychiatric symptoms and psychosocial functioning. Results on the Child and Adolescent Functional Assessment Scale demonstrated considerable gains in the following areas: Home, school/work, social behavior, self-harm, thinking/communication, and substance use. During the intervention, she went from failing several of her classes to graduating from high school. In addition, she made the Honours' List in her first semester at a local community college. A discussion of intervention pluses and pitfalls specific to the case highlight the necessity to influence the various spheres of the young person's life.
