At the time of his initial evaluation he scored in the clinically significant range in all areas on the Autism Diagnostic Interview-Revised)(ADI-R). He was also administered Module 1 of the Autism Diagnostic Observation Schedule (ADOS) with scores consistent with Autistic Disorder as well. He was not able to engage in standardized assessment of his intellectual ability at that time. A nonverbal measure was attempted but rather than using the response cards to provide responses to test items, he became fixated on them. Similarly, he became intensely interested in the spiral binding on one of the stimulus books but was not interested in using the test materials as the examiner asked him to.
Joey was diagnosed with Autistic Disorder.
