Disclosing an autism diagnosis improves ratings of candidate performance in employment interviews

Employment interviews can be challenging for autistic people. In addition to standard interview procedures often being inaccessible, features associated with autism (including atypical emotional expression, eye-contact, and gestures) may lead to negative first impressions. Research using vignettes and 'thin slices' of communication indicate that perceptions of an autistic individual can be improved when their autism diagnosis is disclosed. Here, we examined the impact of diagnostic disclosure on judgements of autistic adults undergoing an entire mock employment interview. A total of 119 participants (known as 'raters') watched a video of an autistic candidate's mock employment interview, after which they provided overall impressions of the candidate on factors such as confidence, motivation, and knowledgeability. Raters were either (1) unaware of the interviewee's diagnosis, (2) aware of their diagnosis, or (3) aware of their diagnosis and provided with information about autism. Results indicate that diagnostic disclosure improved perceptions of autistic candidates across all dimensions compared to when raters were unaware of their diagnosis. The provision of additional information about the diagnosis did not further improve ratings. The findings have important implications for employers and autistic people, who should consider the potential impact of diagnostic disclosure prior to interviewing for a role.Lay Abstract Employment interviews are challenging for many autistic people, for example, due to difficulties with interpreting questions. Autistic people also have differences in non-verbal communication, such as emotional expression, eye-contact, and gestures, with research showing that these factors negatively affect first impressions. Some studies have shown that perceptions of autistic people are more positive when the person observing them, such as an interviewer, is already aware of their diagnosis. However, previous research has not studied how disclosing one's autism diagnosis affects perceptions of a candidate undergoing a full employment interview. Participants in this study acted as raters, who watched a video of an autistic person undergoing a mock employment interview with a researcher, and then rated their overall impressions of them on factors important to real-world hiring decisions, such as confidence, motivation, and knowledgeability. Prior to watching the interview, raters were either (1) not aware of the interviewee's diagnosis, (2) made aware of their diagnosis, or (3) made aware of their diagnosis and provided with additional information about autism, such as differences in behaviours and communication. The results show that disclosing an autism diagnosis improved ratings compared to not disclosing the diagnosis. Providing additional information about autism alongside the diagnostic label did not improve ratings further. The findings are important for employers and autistic people; employers should consider improving procedures by which autistic people can disclose their diagnosis prior to interview should they wish, and autistic people may wish to consider the potential benefits of disclosing their diagnosis.
