Considerable empirical evidence suggests early recognition of autism and access to support result in long-term positive outcomes for children and youth on the spectrum and their families. However, children of racialized families are often diagnosed at later ages, are more likely to be misdiagnosed, and experience many barriers to service access. There is also a paucity of research exploring the experiences of parents from specific immigrant groups caring for their children on the spectrum in Canada, many of whom identify as members of racialized communities. As such, the main aim of the study was to examine how South Asian immigrant parents in Canada are experiencing available care programs and support. Another aim was to examine their perceptions of social stigma associated with autism. We conducted an inductive thematic analysis of qualitative data from nine interviews with South Asian parents living in Ontario, Canada. Findings confirmed barriers to an autism diagnosis and to service access. Additionally, parents reported pronounced autism stigma, which enacted impediments to timely diagnosis, service access, and health-promoting behaviors. Findings also revealed that parents experience considerable caregiver stress and psychological distress. The generated evidence is anticipated to inform equitable policy, programming, and practices that better support the needs of children on the spectrum and their immigrant families.
