Camouflaging involves various strategies employed by autistic individuals to modulate the visibility of their autistic characteristics in social situations and is thought to be primarily motivated by psychosocial factors. Most studies to date have examined a limited number of psychosocial factors related to camouflaging. This study tested an integrated model encompassing several hypothesised individual psychological (i.e. fear of negative evaluation, self-esteem, autistic identity) and broader sociocultural predictors (i.e. perceived stigma, vulnerability events, cultural tightness-looseness, independent and interdependent self-construal). Participants were 225 autistic adults (18-77 years; 60.9% female), who completed self-report measures online. Path analysis partially supported the model, explaining about 25% of the variance in camouflaging. Several sociocultural factors -- perceived stigma, cultural tightness and independent and interdependent self-construal -- were indirectly associated with camouflaging through individual psychological factors. Notably, greater vulnerability to negative life events was the only sociocultural factor directly contributing to more camouflaging, without mediation by individual psychological factors. Fear of negative evaluation emerged as a strong predictor, mediating most relationships between broader sociocultural factors and camouflaging. Our findings highlight key psychosocial factors as crucial targets for social change, advocating a shift from stigmatisation to acceptance and inclusion to alleviate the pressure on autistic people to camouflage.
