title: Advancing health literacy measurement: a pathway to better health and health system performance.
abstract: The concept of health literacy initially emerged and continues to gain strength as an approach to improving health status and the performance of health systems. Numerous studies clearly link low levels of education, literacy, and health literacy with poor health, poor health care utilization, increased barriers to care, and early death. However, theoretical understandings and methods of measuring the complex social construct of health literacy have experienced a continual evolution that remains incomplete. As a result, the seemingly most-cited definition of health literacy proposed in the now-decade-old Institute of Medicine report on health literacy is long overdue for updating. Such an effort should engage a broad and diverse set of health literacy researchers, practitioners, and members of the public in creating a definition that can earn broad consensus through validation testing in a rigorous scientific approach. That effort also could produce the basis for a new universally applicable measure of health literacy. Funders, health systems, and policymakers should reconsider their timid approach to health literacy. Although the field and corresponding evidence base are not perfect, health literacy-especially when combined with a focus on prevention and integrative health-is one of the most promising approaches to advancing public health.
