Functional gender differences in autism: An international, multidisciplinary expert survey using the International Classification of Functioning, Disability, and Health model.

In this study, we explored if professionals working with autistic people in different regions of the world perceive differences between females and males diagnosed with the condition. A total of 131 professionals responded to a survey that included an open question about gender differences in autism. Of these, 32 responded that they do not perceive gender differences in autism. The information provided by the other 99 experts was analyzed to identify common patterns. Three main differences were found, (1) where professionals described differences in core symptoms of autism, and that autistic females were less similar to the conceptualization of autism. In (2) , professionals described that autistic males display more apparent problems including hyperactivity, while autistic females were perceived as having more internalizing issues such as anxiety and eating disorders. In the last category, (3) , experts perceived autistic females as more socially motivated, and more inclined to camouflage social difficulties, making their challenges less evident. Professionals also perceived differences in the social environment, for example, that autistic girls receive more support from their peers while autistic boys are more often bullied. Our results suggest that professionals working in different parts of the world acknowledge gender differences in autism, but also that there might be some regional differences. Finally, we found that gender differences reported by the international professionals could largely be assessed with a shortened version of the International Classification of Functioning by the World Health Organization, specifically developed for autism.
