Impact of Autism Spectrum Disorder Traits and Social Camouflaging on Presenteeism Among Japanese White-Collar Workers

The decline in mental health among workers in Japan has become a serious concern. Autism spectrum disorder (ASD) traits are increasingly recognized as a potential risk factor for mental health issues, yet few individuals receive a formal ASD diagnosis. This study aims to examine whether undiagnosed but working individuals with strong ASD characteristics differ in factors related to presenteeism (low productivity) compared to their counterparts with fewer ASD traits. In particular, we investigated the impact of social camouflaging—the behavioral adaptation used to mask ASD traits—especially on workers with strong ASD characteristics. An online survey was conducted among white-collar workers aged 20 to 60. The survey included items collecting demographic information (gender, age, marital status, highest level of education completed, employment status, job title, length of employment, and working hours) and included the Japanese versions of four validated instruments to measure aspects of autism traits, social camouflaging, work functioning, and occupational stress. Of the 543 respondents, 139 (25.6%) exhibited strong ASD characteristics. These individuals reported lower productivity than their counterparts. While social camouflaging was observed across all ASD trait levels, it was specifically linked to poorer mental health and reduced productivity among workers with strong ASD characteristics. To support workplace well-being and productivity, it is crucial to increase awareness and understanding of ASD traits in professional settings and create an environment that accommodates diverse work styles.
