This study examined service receipt and unmet service needs among youth with autism spectrum disorders (ASD) in their last year of high school, as well as the youth (intellectual disability, race/ethnicity, autism severity, comorbid psychiatric diagnoses, behavior problems, adaptive behavior) and family (income, parental health, parental depressive symptoms, parental anxiety) correlates of service access. Thirty-nine families of youth with ASD participated. Data were collected via parental interview/questionnaire and youth psychological evaluation. Results suggested that this sample was underserved relative to a nationally-representative cohort. Those with a comorbid psychiatric diagnosis and lower levels of adaptive behavior received more services. Greater unmet needs were reported for youth who were racial/ethnic minorities, who had more behavior problems, and whose parents had greater anxiety.
