Despite an estimated population of 10 million autistic individuals, there is still a significant lack of research on autistic adults in China. This study aimed to investigate the extent and factors influencing community integration (employment, independent living and friendship) and life satisfaction among young autistic adults in China, and compare them with an autistic adult sample with similar characteristics (58%-63% with a reported IQ below 70) from the Netherlands. Data were collected via online surveys to the caregivers of 99 young autistic adults (18-30 years) in China and 109 in the Netherlands, because the autistic adults were not able to fill in the survey independently. Autistic adults in both countries were reported to have limited community integration, as indicated by low rates of employment, limited independent living and few close friendships. Proxy-reported life satisfaction of autistic adults seemed relatively low in both countries, but even lower in Chinese adults, possibly due to limited awareness and acceptance of autism in China, inadequate or inaccessible support services, higher parenting stress, or general cross-country differences in well-being. In general, the findings indicate a common challenge faced by autistic adults with high support needs in both China and the Netherlands.
