Purpose Camouflaging, or the use of strategies by autistic people to minimize the visibility of their autistic traits in social situations, is associated with stress, autistic burnout, depression, and suicidality among autistic adults. However, little is known about how autistic children and adolescents experience camouflaging, limiting our understanding of its onset and development. The present study filled this knowledge gap by examining camouflaging behaviour among autistic children and adolescents using a photo-elicitation approach.Methods Eight autistic children and adolescents aged 10 to 14 years (M = 11.88, SD = 1.89) attended an orientation session and were given two to three weeks to take photographs on the topic of camouflaging. Individual interviews were conducted with each participant about their photos. Inductive thematic analysis and an interpretive engagement framework were used to identify major themes within participant interviews and images.Results Qualitative analysis identified 12 themes reflecting motivations to camouflage (as a response to negative social experiences, as a learned habit), contexts of camouflaging (e.g., the audience), strategies and behaviours used to camouflage (suppressing autistic stimming behaviour, hiding the self), and perceived consequences of camouflaging (internal conflict, stress, needing time to recharge).Conclusion Results highlight that autistic children and adolescents as young as 10 years old engage in camouflaging behaviour which can be pervasive and automatic, and that this can be a stressful, confusing, and energetically draining experience. Better understanding of the development and experience of camouflaging in childhood can inform prevention of mental health concerns in adulthood.
