A potential new data source for assessing the impacts of health reform: Evaluating the Gallup-Healthways Well-Being Index.

Background: Existing national health-related surveys take several months or years to become available. The Affordable Care Act will bring rapid changes to the health care system in 2014. We analyzed the Gallup-Healthways׳ Well-Being Index (WBI) in order to assess its ability to provide real-time estimates of the impact of the ACA on key health-related outcomes.

Changes in Self-reported Insurance Coverage, Access to Care, and Health Under the Affordable Care Act.

Importance: The Affordable Care Act (ACA) completed its second open enrollment period in February 2015. Assessing the law's effects has major policy implications.

Objectives: To estimate national changes in self-reported coverage, access to care, and health during the ACA's first 2 open enrollment periods and to assess differences between low-income adults in states that expanded Medicaid and in states that did not expand Medicaid.
