This study tested the "spectrum hypothesis," which posits that children and adolescents with high functioning autism (HFA) differ "quantitatively" but not "qualitatively" from typically developing peers on self-reported temperament. Temperament refers to early-appearing, relatively stable behavioral and emotional…

Although self-reported measures are frequently used to assess adults with autism spectrum disorders (ASD), the validity of self-reports is under-researched in ASD. The core symptoms of ASD may negatively affect the psychometric properties of self-reported measures. The aim of the present study was to test the validity and reliability of…

To examine the factor structure of temperament in 5-10-year-olds with Williams syndrome, an exploratory factor analysis was conducted on the responses of parents of 192 children on the children's behavior questionnaire. Four factors were identified. Two corresponded to factors reported for typically developing children: effortful control and…

The study examines the relationship between Asperger's Disorder (AD) and Schizotypal Personality Disorder (SPD), mutually exclusive but similar diagnoses ["DSM-IV-TR;" American Psychiatric Association (2000). "Diagnostic and statistical manual of mental disorders." Washington, DC: Author]. The literature and comparison of…

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…

Affect regulation (AR) and temperament were examined in children with Autism Spectrum Disorder (ASD). To determine AR, children were exposed to a mildly frustrating situation. Temperament was assessed by the Children's Behavior Questionnaire (CBQ). Children with ASD showed greater variability in AR and used less effective AR strategies compared to…
