Purpose: The objective of this systematic review was to describe the prevalence and processes of disability disclosure for persons with autism spectrum disorder. Methods: Systematic searches of seven international databases revealed 26 studies meeting our inclusion criteria. We analyzed these studies with respect to participant demographics, methodology, results and quality of the evidence. Results: Among the 26 studies, 7006 participants (aged 13-75, mean 28.1 years) were represented across seven countries. Our findings showed that rates of disclosure and receiving workplace accommodations varied considerably. Benefits of disclosing in the workplace included greater acceptance and inclusion, receiving accommodations, and increasing awareness about autism. Limitations of disclosing to employers involved experiencing stigma and discrimination. Factors affecting decisions to disclose included age at diagnosis, social demands of the job, and workplace policies. Types of accommodations that were received or desired included adjustments to the job interview process, schedules (i.e., flexibility, working from home), job content or working conditions, environment (i.e., lighting, quiet space); support with communication and social skills; and disability awareness training for their workplace colleagues. Conclusions: Our findings highlight that disclosing a condition of autism in the workplace and requesting accommodations is complex. More research is needed to explore processes of disclosing and accommodation and how these processes vary by autism sub-type, gender, and industry type.
