Pediatric bipolar disorder (PBD) has been associated with a number of negative behavioral, academic, and interpersonal outcomes for children and adolescents. It initially received a disruptive behavior disorder diagnosis. High rates of comorbid anxiety disorders have also been found in children with PBD. Psychoeducational psychotherapy (PEP) uses a biopsychosocial model and combines family therapy, psychoeducation, and cognitive behavioral therapy (CBT) techniques with the goal of helping families to better understand and manage the symptoms of PBD and coordinate more effective treatment. This chapter focuses on a description of PEP, including three key interventions of this therapeutic approach: Psychoeducation and Motto, Building a Tool Kit, and Thinking-Feeling-Doing. PEP is a manual-based treatment designed for youth with mood disorders and their caregivers, broken down into separate youth and caregiver sessions. Sessions focus primarily on psychoeducation and skills building and are delivered in individual family (IF-PEP) and multiple family formats (MF-PEP).
