Project Goal: The project evaluates the effectiveness of an innovative Nurse-Community Health Worker (CHW)-Family Partnership intervention designed to promote COVID-19 testing uptake, adoption of COVID-19 control measures, and mutual aid capacity at the household level. Endorsed by community members, this project extends the Nurse-Family Partnership model, which has been shown to be effective in improving maternal and child health outcomes, to include CHWs who will provide culturally-appropriate support to families, addressing stigma, medical mistrust, and other common barriers to engagement in COVID-19 testing and prevention for underserved communities and socially vulnerable populations.
