Time-Lag Between Diagnosis of Autism Spectrum Disorder and Onset of Publicly-Funded Early Intensive Behavioral Intervention: Do Race–Ethnicity and Neighborhood Matter?
Health coverage of early intensive behavioral intervention (EIBI) for children with autism spectrum disorder (ASD) is rapidly expanding across the United States. Yet we know little about the time-lag between diagnosis and treatment onset. We integrated administrative, Medicaid claims, and Census data for children in an EIBI Medicaid waiver (n = 473) to examine the relationship between time-lag and (a) child race–ethnicity and (b) neighborhood racial composition, poverty, affluence, and urbanicity. We explored whether the relationship between child race–ethnicity and time-lag varies by neighborhood characteristics. Average time-lag between diagnosis and treatment onset was nearly 3 years. Child race–ethnicity and neighborhood characteristics did not predict time-lag. Reducing time-lag is critical to ensuring that children with ASD receive treatment as early as possible.
