Access to Part C, Early Intervention for children younger than 4 years evaluated for autism spectrum disorder

Abstract

Despite consensus on the importance of early detection and intervention for autistic children, health disparities exist, limiting access to timely services. One specific service type in the United States is Individuals with Disabilities Education Act, Part C Early Intervention programs, which are federally funded interventions for children birth-to-three with developmental delays. This study aimed to assess access to Part C, Early Intervention services for children who were evaluated for autism spectrum disorder and to examine factors that predicted parent-reported access to these services. This study extracted sociodemographic and service access data from the medical records of 709 children aged 12–40 months who were evaluated for autism spectrum disorder. Results showed that only 50% of the sample had reportedly accessed Part C, Early Intervention services. Those who identified as Black had decreased odds of having accessed Part C, Early Intervention, relative to those who identified as White, while those with a lower age of first parent concern had increased odds of having accessed Part C, Early Intervention. When inputting the independently significant variables into the model, both variables, identifying as Black and a lower age of first concern, remained significantly associated with accessing Part C, Early Intervention. Future work should investigate how these disparities come to be. Lay abstract Health disparities are defined as preventable differences in the opportunities to achieve optimal health outcomes experienced by marginalized and underrepresented communities. For families with autistic children, health disparities limit accessing early intervention services—which have been found to improve quality of life and other outcomes. One specific early intervention service in the United States is Individuals with Disabilities Education Act, Part C Early Intervention programs, which are federally funded interventions for children birth-to-three with developmental delays. This study adds to this topic by examining which factors impact accessing Part C, Early Intervention services for children who were evaluated for autism. Results showed that only half of the sample received these services despite there being concerns about development for all children. In addition, results showed that those who identified as Black had decreased odds of having accessed Part C, Early Intervention compared to those who identified as White. These results suggest that there are disparities when it comes to accessing important early intervention services that may be negatively impacting the Black autistic community.
