Abstract

Abstract Background: Comorbid anxiety disorders are prevalent in children with autism spectrum disorders (ASD), but only a minority receives adequate treatment for anxiety. Cognitive behavioral therapy (CBT) has been shown to be effective in treating anxiety disorders. The objectives of the present pilot study were to test the feasibility of the CBT program “Less stress” for comorbid anxiety disorders in children with ASD and explore whether an improvement in diagnostic outcomes for anxiety disorders and symptoms of anxiety was found after treatment. Methods: Participants were ten children diagnosed with ASD and anxiety disorders (eight boys, mean age = 9.5 years, range 8 - 12 years). The “Less Stress” program includes three months of weekly treatment sessions followed by three monthly booster sessions. Five therapists participated. A standardized semi-structured diagnostic interview with the mothers was used to assess comorbid disorders. Child anxiety symptoms were measured with the Revised Child Anxiety and Depression Scale (RCADS). Results: The therapists found the manual easy to use but adaptations were necessary, particularly shorter sessions due to frequent (n = 7) comorbid Attention-Deficit/Hyperactivity Disorder. The participants found the program useful and the parents noted that they had learned methods they could continue using after the end of the program. Eight of ten children completed the treatment. Seven of the eight completers benefited from the program. Five of those seven children were free from all anxiety disorders, while two had fewer anxiety disorders. On a group level, a significant mean reduction of anxiety symptoms (RCADS) was found after treatment. Conclusion: The therapists found the “Less stress” program to be a feasible intervention in a sample of children with ASD and comorbid anxiety. The significant reduction of anxiety after treatment is promising, but a replication in a larger and more rigorous study is needed to investigate the effectiveness of the intervention.
