Brief Summary

Autism spectrum disorder (ASD) is associated with high rates of psychiatric comorbidity, particularly anxiety and depressive disorders, which contribute to significant impairment for affected youth and their families. Although cognitive behavioral therapy (CBT) is recommended as a first-line treatment for anxiety and depression in children and adolescents, there is a lack of evidence-based interventions specifically adapted for youth with ASD and co-occurring emotional disorders. The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Children and Adolescents (UP-C/UP-A) is a CBT-based intervention targeting shared mechanisms underlying anxiety and depression. A parent-mediated adaptation, the Unified Protocol-Adolescent Autism Parent Group (UP-A-AST), has been developed to address the specific needs of adolescents with ASD and co-occurring anxiety and/or depressive disorders. Preliminary quality improvement work has shown promising results. This study aims to evaluate the feasibility, acceptability, and preliminary effects of the UP-A-AST Parent Group in a child and adolescent outpatient psychiatric setting. The study will include parents of adolescents aged 12-17 years with ASD and co-occurring anxiety and/or depressive disorders. Outcomes include changes in adolescents' psychiatric symptoms and functional impairment, as well as parents' perceived parenting competence. Additionally, parents' experiences of participating in the intervention will be explored.
