In this study, the investigators will examine the feasibility, acceptability, and preliminary efficacy of a novel, behavior-based approach for treatment of depression symptoms in adolescents with ASD (i.e., Behavioral Activation for Adolescents with ASD, BA-A). BA-A is a 12-session manualized treatment that utilizes established behavioral activation strategies and incorporates common mental health treatment adaptations for young people with ASD. For this project, the investigators will pilot BA-A with 23 adolescents (12-17 years of age) with ASD and clinically significant depression symptoms. To investigate BA-A feasibility, the investigators will examine treatment session attendance and therapist treatment fidelity. To investigate BA-A acceptability, the investigators will utilize a mixed methods approach, inclusive of surveys and qualitative interviews, to inform BA-A protocol refinement. To investigate BA-A preliminary efficacy, the investigators will examine depression symptoms, as well as secondary outcome measures, at pre-treatment, post-treatment, and one-month follow-up.
