Masking is a form of identity management involving consciously or unconsciously suppressing aspects of identity and action. Often seen in socially marginalised groups, it is found to contribute towards poorer outcomes for autistic people and is related to higher prevalence of suicidality, exhaustion & burnout, and mental health difficulties. Though masking has been predominantly framed as a social strategy to 'blend in' with neurotypical (non-autistic) people, emerging research suggests that masking can also form as a response to stigma and from traumatic experiences. Taking an intersectional lens to consider how autistic identity may interact with other aspects of selfhood, the authors will provide a holistic understanding of the most up-to-date evidence with the aim to develop solid knowledge and practice in health and education.
