The Relationship Between Anxiety and Repetitive Behaviours in Autism Spectrum Disorder

摘要

Children with Autism Spectrum Disorder are vulnerable to anxiety. Repetitive behaviours are a core feature of Autism Spectrum Disorder (ASD) and have been associated anxiety. This study examined repetitive behaviours and anxiety in two groups of children with autism spectrum disorder, those with high anxiety and those with lower levels of anxiety. Children with high anxiety had more repetitive behaviours than those without anxiety. Within the anxiety sample, higher levels of insistence on sameness were associated with more anxiety. No association was found between sensory motor repetitive behaviours and anxiety in this group. In the non-anxious sample, anxiety was associated with sensory motor repetitive behaviours. These findings indicate a differential relationship for repetitive behaviours in relation to anxious and non-anxious children with ASD.
