Feasible Adaptation of ESDM for Statewide Implementation: A Look at Potential Effects,Implementation Conditions,and Cost

Abstract

This article describes the development and use of a first of its kind statewide implementation of an adapted Early Start Denver Model (ESDM). Supported by a collaborative partnership between stakeholders that included families, state agencies, and a state university, the intervention was implemented within the existing framework of a northeastern state’s relationship-based Individuals with Disabilities Education Act (IDEA) Part C early intervention program. Participants were 194 families. The study examined the effectiveness and implementation costs of an adaptation of the ESDM using a coaching model to inform statewide implementation to improve outcomes for young children with autism spectrum disorder (ASD) in rural and low-resource states. Results indicated 194 children who received a monthly average of 10.90 hr of adapted ESDM for an average of 12 months demonstrated an improvement in the frequency of ASD symptomology for a total cost of US$2,511/child. Intervention intensity and child factors demonstrated varying influence on outcomes. This study contributes to the literature by demonstrating the potential for positive impact of an evidence-based practice scaled to a statewide model of early intervention for young children with ASD.
