Background: The diagnostic process for autism spectrum disorder (ASD) can be difficult for families. Growing evidence suggests that the diagnostic process may vary as a function of sociodemographic factors, such as socioeconomic status. The purpose of this study was to extend findings related to families' experiences obtaining a diagnosis and accessing services for their young child with ASD. Method: A mixed methods approach was used in this study, in which 46 families with children with ASD participated. A chi-square analysis compared ratings of parental satisfaction with the diagnostic process and current services between sociodemographic groups, and this was supplemented by thematic analysis of relevant open-ended questions. Results: Results indicated that satisfaction ratings varied significantly by maternal education and family income levels. Ratings of satisfaction with the child's paediatrician also differed by family income. Major themes from the open-ended questions are discussed. Conclusions: Results support assessing satisfaction and barriers in families seeking healthcare and school-based services to facilitate access to services.
