COOLIDGE AUTISTIC SYMPTOMS SURVEY (CASS)

The CASS is an 84-item, parent-as-respondent inventory that has been designed to assess the Autism Spectrum Disorder according to the criteria in the new DSM-5. It is appropriate for children ages 3 years old to 17 years old, and it has been empirically demonstrated to be able to diagnose children in the Autism Spectrum from mild to severe, including children diagnosed with Autism, Asperger's Disorder, and High Functioning Autism. The CASS has also been empirically demonstrated to be able to distinguish between children in the Autism Spectrum from purportedly normal children and children with traits and features of or a suspected diagnosis of Schizoid Personality Disorder. The CASS is highly reliable and has been validated on multiple samples of children diagnosed with Autism (mild to severe), Asperger's Disorder, High Functioning Autism, Schizoid Personality Disorder, and purportedly normal children.
