Person-first language is considered a central component to recovery oriented person-centred care; however, there is a growing adoption of identify-first language among autistic advocates. Mental health nurses require awareness of critical autism issues given the high prevalence of comorbid psychopathology. This scoping review of literature from 2010 to 2018 regarding identifying language for people on the autism spectrum identified a paucity of research that systematically explored and considered antagonisms, representation, and potential consequences of either of the current modes of identifying language becoming dominant. Mental health nurses should appreciate the complexity within identifying language and adopt context dependent language.
