This course introduces students to individual, interpersonal, and societal influences on health, and how such factors influence health across populations and create disparities in health. Using this knowledge as a foundation, the course examines how digital health technologies can be designed to address wellbeing barriers that disproportionately and unfairly diminish the health of subpopulations, eliminate preventable gaps in health between populations, and help all individuals achieve their highest possible state of health. Furthermore, this course examines how varied influences on health shape access to, utilization of, and the impact of digital health systems. Students will learn how to apply theory, empirical insights, and perspectives from the social, behavioral, and public health sciences in the design and evaluation of digital health systems. Foundations of public health will be examined; additionally, the course will have a central focus on applying human-centered design concepts to the domain of digital health.
