Unformatted text preview: Abstract This study investigated personality and neurobehavioral differences between 16 children with Aspergers Disorder, 15 children with High-Function- ing Autism (HFA), and 31 controls, all ranging in age from 517 years, M age = 10.7 years, SD = 3.0. Par- ents rated their childrens behaviors on a 44-item autistic symptoms survey and on the 200-item Coolidge Personality and Neuropsychological Inventory (Coo- lidge, Thede, Stewart, & Segal ( 2002 a). The Coolidge Personality and Neuropsychological Inventory for Children (CPNI): Preliminary psychometric charac- teristics. Behavior Modification, 26 , 550566). The results indicated that the two clinical samples were significantly elevated on the Executive Function Defi- cits scale and Attention-Deficit/Hyperactivity Disorder (ADHD) scale compared to controls. There were more similarities than differences between the two clinical samples on the personality scales, although the Aspergers group scored significantly on the two scales with anxiety components. Keywords Aspergers disorder High-functioning autism Coolidge personality and neuropsychological inventory Executive functions deficits scale Autism Personality disorders Introduction Aspergers Disorder is categorized in the Diagnostic and Statistical Manual of Mental Disorders ( DSM-IV- TR; American Psychiatric Association, 2000 ) as a pervasive developmental disorder. Children with Aspergers Disorder typically exhibit severe and chronic impairments in social interactions, restrictive and repetitive patterns of behaviors, interests, and activities, and significant impairment in social, occu- pational, and other areas of functioning. Aspergers Disorder, however, differs from Autistic Disorder in DSM-IV-TR only in that it specifically excludes cog- nitive and language delays. Aspergers Disorder is also thought to have a greater prevalence than Autistic Disorder, occurring in 2636 cases per 10,000 children as opposed to Autistic Disorder which may occur in as few as 45 cases per 10,000 (Fombonne, 1999 ) to as many as 516 cases per 10,000 children (Ehlers & Gillberg, 1993 ; Wing, 1993 ). High-Functioning Autism (HFA), although it appears frequently in the literature, is not listed as an official DSM-IV-TR diagnosis. The diagnosis of HFA has typically been used to describe individuals with Autistic Disorder that have an IQ above the mentally retarded range (>69), are verbally higher functioning, and presumably require a different treatment ap- proach. Whether HFA and Aspergers Disorder are the same or different disorders remains controversial (see Schopler & Mesibov, 1998 ; Tonge, Brereton, Gray, & Einfeld, 1999 , for more complete discus- sions). Currently, most individuals diagnosed with Autistic Disorder are not high functioning. This may, however, be an artifact, because severe cases of aut- ism are more likely to be recognized and diagnosed L. L. Thede F. L. Coolidge ( & ) Psychology Department, University of Colorado at...
