Sex/gender differences in autistic traits, intelligence and executive functions of school-aged autistic children without intellectual disability
摘要
ASD has been more often diagnosed and researched in men than women, shaping diagnostic criteria which may not adequately capture the female presentation. Examining differences between girls and boys with ASD could enhance diagnostic accuracy and help reduce gender-related biases in research and clinical practice. The aim of this research was to analyze potential differences in autistic traits, intelligence, and executive functions of school-aged girls and boys diagnosed with ASD without intellectual disability.
MethodsThe research sample consisted of 79 children with ASD, 20 girls and 59 boys, aged between 6 and 12 years. Autistic traits were measured by Autism Diagnostic Observation Schedule – Second Version and Autism Diagnostic Interview-Revised, intelligence by the Woodcock-Johnson International Editions II, and executive functions by Wisconsin Card Sorting Test and Behavior Rating Inventory of Executive Function 2.
ResultsGirls scored lower in the amount of restricted, repetitive and stereotyped behaviors, but showed more severe deficits in Emotion Regulation, Cognitive Regulation and clinical scales Shift and Initiate, as measured by BRIEF-2.
ConclusionOur results indicate girls with ASD exhibit certain differences from boys with ASD, which may be diagnostically relevant and helpful for their early detection and access to necessary resources and support. Nevertheless, extensive further research on the sex/gender differences and female ASD presentation is still needed.
