    • Abstract:
      Differences in behavioral and cognitive profiles have been suggested to potentially impact the presentation of social and communication symptoms in females with autism spectrum disorder. This study examined gender differences in age of diagnosis, cognitive profiles, social communication symptomatology, and autism spectrum disorder symptom severity in a community-based sample of 566 males and 113 females with autism spectrum disorder ranging in age from 1 year, 9 months to 56 years, 4 months. Results suggest either very small or no gender differences in age at diagnosis, intelligence quotient, cognitive profiles, or autism spectrum disorder symptom severity. This is a departure from clinical lore that females with autism spectrum disorder are more likely to have lower intelligence quotient and more severe impairments. There is a slight difference in symptom severity with females having higher average total Childhood Autism Rating Scale scores, but this difference is likely of minimal clinical significance. In contrast, on the Autism Diagnostic Observation Schedule-Generic, females were found to receive lower scores than males particularly on modules 2 and 3. Across males and females, individuals with stronger verbal problem-solving skills were found to receive lower Autism Diagnostic Observation Schedule-Generic module 3 scores. Given the language demands of this module, additional attention may be warranted when evaluating older children and adolescents for autism spectrum disorder.
