Autistic spectrum disorders (ASD) can be difficult to diagnose in toddlers. This study compared diagnostic measures (ADOS-G, ADI-R, CARS, and clinical judgment using DSM-IV criteria) applied to toddlers.

The functional play of the children with autism was less elaborated, less varied, and less integrated than that of the controls. (Contains references.) (Author/CR)
