Group Depression Treatment for Autistic Youth

Higher rates of depression and suicidal thoughts are reported by autistic adolescents as compared to their non-autistic peers, which is problematic given adverse outcomes (e.g., negative self-esteem, lower academic performance) that are associated with depression. Despite the alarming rates of depression in autistic youth, few interventions have been developed or tested to reduce depression in this at-risk population. An evidence-based intervention for depression in non-autistic adolescents is Cognitive Behavioral Therapy (CBT), which CBT has strong research support for treating depression in non-autistic adolescents according to the American Psychological Association (APA). Autism-adapted CBT programs for anxiety and OCD have outperformed standard CBT approaches for autistic youth; however, autism-adapted CBT programs for depression in autistic adolescents have not been developed with stakeholders nor tested in a clinical setting. To address this gap, an adapted CBT group intervention for autistic adolescents (11-17 years old; middle and high school) with depression was designed in collaboration with autistic stakeholders. In the present study, the feasibility, acceptability, and preliminary efficacy of this 12-week group intervention in improving perception and understanding of self and depressive symptoms will be examined in a pilot, nonrandomized trial with pretest-posttest design. Groups will occur in the Outpatient Clinic of the Department of Psychiatry and Behavioral Sciences at the Vanderbilt University Medical Center (VUMC), and study measures will be administered to adolescents and their parents at four timepoints: baseline (week 0), midpoint (week 6), post (week 12), and follow-up (week 24). Study measures include parent- and self-report measures of adolescent well-being (e.g., perception of self, quality of life, etc.) and clinical interviews of psychiatric symptoms (e.g., depressive symptoms, suicidal thoughts). The significance and size of intervention effects on emotional and behavioral outcomes will be measured using one-way ANOVAs and linear mixed models. If predicted results occur, it will provide information on the feasibility and acceptability of this group intervention, with preliminary empirical support for its efficacy in improving perception and understanding of self and reducing the severity of depressive symptoms in autistic adolescents.
