Diagnostic evaluations for autism spectrum disorders consist of multiple elements. They begin with an interview with the parents about the child’s development. The parents are also interviewed about the child’s adaptive functioning, which includes communication, self-help, social, and motor functioning. With the child, the evaluator assesses the child’s developmental level or cognitive ability, and an assessment of the child’s social functioning and reciprocal interaction is done, in a fun, play-based format.
Measures commonly included in an evaluation of an autistic spectrum disorder are listed below:
- Wechsler Preschool and Primary Scale of Intelligence, Third Edition (WPPSI-III)
- Autism Diagnostic Observation Schedule (ADOS)
- Childhood Autism Rating Scale (CARS)
- Vineland Adaptive Behavior Scales
