Overview
Brief Summary
Anxiety disorders affect 40 to 50% of children with autism spectrum disorders (ASD), contributing to substantial distress and impairment. The goal of this study is to examine the effectiveness of a personalized type of psychotherapy against standard-care psychotherapy for addressing anxiety in youth with ASD.
Detailed Description
Autism spectrum disorders (ASD) are common neurodevelopmental syndromes affecting 1% of U.S. children. Comorbid anxiety disorders affect 40 to 50% of children with ASD, causing substantial distress and impairment over and above that caused by ASD alone. Although standard practice cognitive-behavioral therapy (CBT) has been established as an efficacious and safe treatment for anxiety disorders among typically developing youth, its utility in comorbid cases with ASD remains unknown. To date, no studies have experimentally compared standard practice CBT to a cognitive-behavioral intervention that has been personalized for children with a comorbid presentation of anxiety and ASD. Accordingly, we are proposing a randomized controlled trial to be conducted at three treatment sites to evaluate the efficacy of personalized CBT for anxiety in ASD (Behavioral Intervention for Anxiety in Children with Autism: BIACA) relative to standard practice CBT for anxiety (Coping Cat program). Furthermore, this study will employ a waitlist control group to assess the efficacy of each CBT arm relative to the absence of treatment (i.e., a Waitlist control arm). The proposed research will: (1) examine the efficacy of BIACA relative to Coping Cat, which represents standard practice treatment, and the efficacy of both these treatments relative to a waitlist control group, (2) evaluate the maintenance of treatment gains, (3) examine the impact of personalized intervention on functional outcomes. A total of 201youth across 3 study locations (ages 8-13 years) with ASD and co-occurring anxiety will be randomly assigned to one of the three conditions. The three recruitment sites for this study are University of California, Los Angeles, the University of South Florida (USF), and Temple University. Considering the rising number of children diagnosed with ASD together with the frequency and severity of comorbid anxiety, the proposed work is tailored to the unique needs of youth with ASD and will provide a timely contribution to public health efforts.

Exclusion Criteria
- •Receiving concurrent therapy targeting anxiety, social skills training with homework, or behavioral interventions (e.g., applied behavior analysis). This excludes academic tutoring, occupational therapy, speech therapy, school counseling that is no more than 60 minutes per week in duration, school aides, and social skills training groups that do not include homework and are no more than 60 minutes/week in duration.

- •Child has been nonresponsive to an adequate trial of CBT for anxiety within the previous 2 years.
- •Lifetime bipolar disorder, schizophrenia or schizoaffective disorder.
- •Initiation of an antidepressant medication within 12 weeks before study enrollment or an antipsychotic medication 6 weeks before study enrollment or the child has changed the dose of an established medication within 8 weeks before study enrollment (4 weeks for antipsychotic) or during psychotherapy (unless the dose is lowered because of side effects).
Outcomes
Primary Outcomes
Change From Baseline in Anxiety Severity on the Pediatric Anxiety Rating Scale After 16 Weeks of Treatment.
Time Frame: Baseline and After 16 Weeks of Treatment
This measure is administered by a clinician and assesses anxiety symptom severity on a scale from 0-25 with higher scores corresponding to worse anxiety.
Secondary Outcomes
- Change From Baseline in Anxiety/Depression Severity on the Child Behavior Checklist After 16 Weeks of Treatment.(Baseline and After 16 weeks of treatment)
- Percentage of Participants With Positive Treatment Response as Assessed by the Clinical Global Impressions-Improvement Scale(After 16 weeks of treatment)
- Change From Baseline in Anxiety Related Impairment as Measured by the Childhood Anxiety Impact Scale After 16 Weeks of Treatment.(Baseline and After 16 weeks of treatment)
