title: Which DSM-IV-TR criteria best differentiate high-functioning autism spectrum disorder from ADHD and anxiety disorders in older children?
abstract: Diagnosis of autism spectrum disorder (ASD) is often delayed in high-functioning children with milder and more varied forms of ASD. The substantial overlap between ASD and other psychiatric disorders is thought to contribute to this delay. This study examined the endorsement of DSM-IV-TR diagnostic criteria for ASD based on semi-structured parent interviews across three groups of older children referred to an ASD clinic: 55 children diagnosed with high-functioning ASD, 27 children diagnosed with attention-deficit/hyperactivity disorder (ADHD), and 23 children diagnosed with anxiety disorder. Results indicate that the criteria within the domains of communication and social relatedness were largely able to discriminate the high-functioning ASD group from the ADHD and anxiety disorder groups, but criteria within the domain of restricted/repetitive/stereotyped patterns were not.
