Abstract

The parents/guardians of 50 individuals were surveyed using a semistructured interview to determine the feasibility of this method and to establish ages of symptom onset. Thirty-eight informants were able to recall sufficient detail to allow categorization of the age of symptom onset. Chi-square analysis confirmed a significant association between investigators' categorization and informants' categorization. Contemporaneous presentation was indexed using Childhood Autism Rating Scale, the Autism Behavior Checklist, the Conners Hyperactivity Index, and the Ritvo-Freeman Real Life Rating Scale for Autism. No significant correlations were determined between any of these indices of symptom severity and age of symptom onset.
