The CASO 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 chi Id, and other available records.
Studies show the CASO differentiates children with Autism from those with ADHD with 99.5 per cent accuracy, and from typical children with 100 per cent accuracy. It is equally effective in identifying children who have Autism and normal, or below normal, intelligence.
Simple and brief, the CASO does not require extensive training.
30 CASD Symptoms arc grouped in Six Domains:
• Problems with social interaction
• Atypical communication and development
• Perseveration
• Mood and disturbance
• Somatosensory disturbance
• Problems with attention and safety
Technical Information:
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 (POD-NOS) range.
