School-Based Cognitive-Behavioral Therapy in an Inclusion Model for an Adolescent with Comorbid Major Depressive Disorder, Generalized Anxiety Disorder, and Attention Deficit Hyperactivity Disorder: A Case Study

The goal of the current case study was to illustrate evidence-based cognitive-behavioral treatment (CBT) for an adolescent female with comorbid major depressive disorder, generalized anxiety disorder, attention deficit hyperactivity disorder, suicidal ideations, and a history of multiple involuntary hospitalizations. Multimodal assessment of the child’s symptoms was conducted, including parent, teacher, and child self-report, academic data, and hospital records to inform case conceptualization. Treatment included a combination of psychoeducation, cognitive restructuring, positive self-talk, relaxation skills, and the support of a school-based personal aide. Significant improvements with inattentive, anxiety, and depressive symptoms were reported, with gains being maintained at 1 year follow-up. In addition to a reduction of reported psychosocial problems, treatment benefits also included a decrease in classroom disruptions, improvement in academic performance, and withdrawal of paraprofessional support at school. This study illustrates the use of school-based CBT strategies coupled with additional focused Tier 4 behavior supports as an efficacious treatment for youth with significant comorbidity.
