Which assessment tool is specifically designed for diagnosing autism?

The Childhood Autism Rating Scale (CARS) is specifically designed to aid in the diagnosis of autism spectrum disorders. This instrument evaluates a child’s behavior and ability across various domains that are characteristic of autism, including social interactions, communication skills, and sensory sensitivities. By assessing these specific areas, CARS helps to determine the presence and severity of autism in children.

In contrast, the Behavior Assessment System for Children (BASC) provides a broader evaluation of behavioral and emotional issues and is not exclusive to autism. The Wechsler Adult Intelligence Scale (WAIS) measures intellectual functioning in adults and does not pertain to autism diagnosis. Lastly, the Vineland Adaptive Behavior Scales (VABS) assesses adaptive behaviors necessary for daily living but is not designed specifically for diagnosing autism. Therefore, the CARS is the most focused tool among the options presented for diagnosing autism specifically.
