Health insurance and self-assessed health: New evidence from Affordable Care Act repeal fear.

Self-assessed health is one of the most commonly used health measures by economists. However, changes in self-assessed health are not always accompanied by changes in physical health as measured by clinical outcomes. This study provides suggestive evidence that this discrepancy arises because self-assessed health is significantly influenced by psychological factors. Specifically, when the perceived risk of Affordable Care Act (ACA) repeal increased, as documented by Google Trends data, self-assessed health declined among low-income childless adults living in states that expanded Medicaid under the ACA.
