In Brief

A clinical study evaluating Standard Messaging, Enhanced Messaging, and 3 other interventions for Covid19 and 3 related conditions. Completed, enrolled 1,143 participants across 3 sites.

Detailed Summary

The primary goal of this project is to identify the best messaging and implementation strategies to maximize SARS-CoV-2 testing for children with intellectual and developmental disabilities (IDD) and their teachers to help ensure a safe school environment. Additionally, we will understand nationally the perceptions of COVID-19 and identify facilitators and barriers to help with the adoption of testing in other parts of the US and the necessary strategies to address other mitigation strategies including vaccination.
