This module will introduce the concept of health literacy, as we also examine how health literacy is measured. In lesson one, we will look at some of the social determinants of health that interact with health literacy, as we investigate the link between low health literacy and poor health outcomes. We will also review the Health Literacy Umbrella as a framework for improving health literacy, as we evaluate several policies, solutions, and perspectives for addressing disparities in health literacy. In lesson two, we will explore some of the resources available for measuring health literacy as we consider the many perspectives of health literacy measurement.
