This study investigated personality and neurobehavioral differences between 16 children with Asperger’s Disorder, 15 children with High-Functioning Autism (HFA), and 31 controls, all ranging in age from 5–17 years, M age = 10.7 years, SD = 3.0. Parents rated their children’s behaviors on a 44-item autistic symptoms survey and on the 200-item Coolidge Personality and Neuropsychological Inventory (Coolidge, Thede, Stewart, & Segal (2002a). The Coolidge Personality and Neuropsychological Inventory for Children (CPNI): Preliminary psychometric characteristics. Behavior Modification, 26, 550–566). The results indicated that the two clinical samples were significantly elevated on the Executive Function Deficits 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 Asperger’s group scored significantly on the two scales with anxiety components.
