The goal of this project is to understand the scope of variation in primary care provider (PCP) response to work requirements and lead to the development of targeted guidance and other policy tools to improve PCP consistency and protect physician and patient welfare. The researchers will assess PCPs’ attitudes towards work requirements and the factors that shape their responses towards patients facing new work requirements in KY, IN, AR and NH in a mailed vignette-based survey experiment, and they will seek to understand how key stakeholders from the PCP community in KY, IN, AR and NH are engaged in work requirement implementation, including developing exemption procedures, through qualitative interviews. Deliverables will include a project work plan and final narrative and financial reports. The grantee will also produce paper(s) suitable for publication and present findings at national research meetings and to other stakeholder audiences as appropriate, including policymakers at the federal, state, and local levels, as part of the deliverables for this grant.
