Summary View help for Summary
By tapping into the perspectives of older adults and their caregivers, the University of Michigan National Poll on Healthy Aging (NPHA) helps inform the public, health care providers, policymakers, and advocates on issues related to health, health care and health policy affecting Americans 50 years of age and older.
The poll is designed as a recurring, nationally representative household survey of U.S. adults, which allows assessment of issues in a timely fashion.
Launched in spring 2017, the NPHA is modeled after the highly successful University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health. The NPHA grew out of a strong interest in aging-related issues among many members of the University of Michigan Institute for Healthcare Policy and Innovation (IHPI), which brings together more than 600 faculty who study health, health care and the impacts of health policy. IHPI directs the poll which is sponsored by AARP and Michigan Medicine, the University of Michigan academic medical center.

The GfK Group (GfK, formerly Knowledge Networks) conducted the National Poll on Healthy Aging Wave 1 on behalf of University of Michigan. To sample the population, GfK sampled households from its KnowledgePanel, a probability based web panel designed to be representative of the United States.
Once assigned to a survey, respondents received a notification email letting them know there was a survey available for them to take. This email notification contained a link that sent them to the survey questionnaire. No login name or password was required.
After three days, automatic email reminders were sent to all non-responding panel members in the sample. Beyond the standard email reminder on day three of the field period, additional email reminders to non-responders were sent on day 7 and day 14 of the field period.
