About This Product
BY SUSAN D. MAYES, PHD
Here is a quick way to screen for, and diagnose, children and adolescents with autism spectrum disorders. The CASD rates 30 symptoms of autism, covering six domains:
- Problems with social interaction
- Somatosensory disturbance
- Atypical communication and development
- Problems with attention and safety
Symptoms are scored as present or absent based on information drawn from various sources, including teacher, caregiver, parent, observation of the child, and available records.
The CASD can be used with any child between 1 and 17 years of age. Practical, cost-effective, and completed in just 15 minutes, it informs both diagnosis and treatment planning. Although the test requires no training, users can refer to an optional DVD for administration, scoring, and diagnostic guidelines.
Studies show that the CASD is 100% accurate in differentiating children with autism from typical children. Similarly, it demonstrates 99.5% accuracy in distinguishing youngsters with autism from those who have ADHD. The checklist also shows excellent congruence with DSM-IV–based clinical diagnoses and with other measures of autism.
