Description
The CASD offers a quick, valid means of screening for, and diagnosing, children with Autism, regardless of age, IQ or Autism severity. It consists of a comprehensive list of 30 symptoms of Autism, scored as present (either currently, or in the past) or absent, based on a semi-structured interview with the parent; information from the child’s teacher or child care provider; observations of the child, and other available records. The standardization sample included more than 1,000 children with Autism (1-17 years of age, IQs of 9-146), over 500 typical children, and children with other diagnostic groups (e.g., ADHD). All children in the Autism group had a total CASD score at, or above, the Autism cutoff of 15, which is the cutoff for both high- and low-functioning Autism. Scores of 10-14 are in the Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) range.
