Self-reported masking in sexual minority and heterosexual autistic adults.

Masking can include suppressing or concealing certain behaviors to appear "non-autistic" and is one response to the excess social stressors of being a neurominority in a neurotypical-majority society. It is important to understand how persons who are multiply marginalized (e.g. an autistic person assigned female sex at birth who is bisexual), who experience multiple layers of excess social stressors, may face additional pressures to conceal their authentic selves. Autistic persons may be more likely than neurotypical persons to identify with a sexual minority orientation, such as asexual, bisexual, gay or pansexual. To advance our understanding of how marginalized identities may be associated with masking, we examined self-reported masking using the Camouflaging Autistic Traits Questionnaire in a sample of autistic adults ( = 462). After matching participants for assigned sex at birth and age, and after controlling for these effects in modeling, we found that sexual minority autistic adults reported significantly higher levels of masking relative to heterosexual autistic adults. We situate these findings within literatures on masking, minority stress, and stigma.Lay AbstractMasking can include hiding certain behaviors to appear "non-autistic." Masking is one response to the stress of being autistic in a non-autistic world. Being autistic is only one part of someone's identity, though. Other parts of a person's identity include things like a person's sexual orientation. Autistic people are more likely than non-autistic people to have a sexual orientation other than heterosexual, like asexual, bisexual, gay, or pansexual. People who are both autistic and a sexual minority may experience social stress because of different pressures from society. These different pressures may mean sexual minority autistic adults feel pressured to social camouflage more than heterosexual autistic adults. Thus, we compared masking in sexual minority autistic and heterosexual autistic adults. In the statistical models, we controlled for two other factors that may impact masking: sex assigned at birth and age. We found that sexual minority autistic adults reported significantly higher levels of masking relative to heterosexual autistic adults. We discuss how these findings fit within previous research on masking and minority stress.
