Autistic students report feeling lonely, rejected by peers which is associated with poorer well-being and lower academic results. This study aims to evaluate the effect of autism phenotype and diagnosis disclosure on students' desire for social distance from autistic students and factors related to social distancing. 303 students (72.3% women; mean age = 22.37 years) participated in this study. Each participant was assigned to one of the six vignettes depicting students of different gender and diagnostic status. Respondents' willingness to engage in different social situations, type and quality of prior contact with autism, autism knowledge and social desirability bias were measured. Results showed that students desired greater social distance from autistic males compared to autistic females, as well as from peers with non-disclosed diagnosis compared to those with disclosed diagnosis. Greater autism knowledge was related to less desire for social distance in non-disclosure, disclosure and in male autism phenotype conditions. Higher quality of contact was associated with less desire for social distance from autistic students with disclosed diagnosis. Type of contact was not related to social distance. Findings suggest that autistic male students and individuals with non-disclosed diagnosis might be more vulnerable to social exclusion.
