Health insurance and self‐assessed health: New evidence from Affordable Care Act repeal fear
研究发现，当《平价医疗法案》被废除的风险上升时，居住在扩大医疗补助州的低收入无子女成年人的自评健康下降，表明心理因素显著影响自评健康。
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.
