Exploring the Impact of Geographic and Community Factors on Access to Part C Early Intervention and Autism Diagnosis: An Investigation Using Secondary Datasets
Matthew Adam Zellner
ProQuest LLC, Ph.D. Dissertation, Northwestern University
The present dissertation features two studies utilizing secondary data to explore the impact of geography on access to and utilization of early developmental services, including Part C early intervention (EI) and autism diagnosis. Both studies examined the role of geography on a micro-level using geographic information system (GIS) based accessibility and availability approaches with secondary datasets from two midwestern states. The first study examined differences in geographic access to EI providers between urban and rural areas in Illinois. Overall, rural areas in Illinois had substantially fewer providers and required significantly longer travel distances to access services compared to urban areas. There were also notable differences by race: Families faced longer distances to SLPs and DTs in majority Black rural areas compared to minority Black rural areas; however, the inverse was true of majority Latinx areas. These findings speak to the multitude of challenges faced by children with disabilities in rural areas in the United States. The second study explored the role of geographic access to diagnostic and referral service providers on age at autism diagnosis in Indiana. Initial investigations of the moderating influence of provider type and urbanicity were inconclusive and failed to provide evidence for the role of referral providers in age at diagnosis. However, findings by race identified a population affected by provider distance, Asian Americans, and predicted differences in mean ages at diagnosis based on the dataset may provide additional support for changes in diagnostic patterns by race recently identified by other researchers.
