Abstract

We examined receipt of general early intervention services and autism-specific specialized services across demographic groups among toddlers with autism diagnoses who were receiving Part C Early Intervention (EI). Latent class analysis (n = 508) identified five demographically distinct subgroups associated with intersecting marginalization and privilege. Analyses of longitudinal parent interviews (n = 225) revealed service receipt disparities across these demographically distinct latent classes; children from White, U.S. born, English-proficient parents with incomes above poverty level received more EI services (M = 12.0 h/week) than other subgroups, with children from Latiné immigrant families receiving the fewest hours (M = 6.9 h/week). Across all groups, average intervention hours were 8.8 h/week. Despite early identification, racial, ethnic, and other sociodemographic disparities were evident in receipt of Part C Early Intervention services, indicating the need to address barriers to equitable care.
