Autistic adults experience a high level of distress. Finding new ways to support their well-being is an important goal for researchers and clinicians. We assessed the way autistic adults view their autism, as a disorder or as a type of mind (neurodiversity), and the level they integrate with other autistic people, and we checked how those factors contribute to their well-being. People who see autism rather as a type of mind than as a disorder had higher self-esteem. People who view themselves as more similar to other autistic people felt more stressed, but this result was not accurate for people who view autism as a type of mind. Clinicians should be sensitive to the way autistic people understand autism and to what extent they identify with the autism community, because it may relate to their well-being.
