Executive Function Intervention for Young Children with Down Syndrome

This project aims to refine and evaluate EXPO (EXecutive function Play Opportunities), a new caregiver- mediated intervention designed to support the development of executive function in children with Down syndrome. In this R61/33, we will continue the intervention development process by transforming EXPO into an adaptive intervention, with modifications for children who show greater degrees of developmental delay and who may respond more slowly to EXPO. We will then test the restructured EXPO adaptive intervention with a two- arm, Singly Randomized Trial that will evaluate the effectiveness of EXPO pathways.
