“Global Health is Local Health” is a term derived from the medical field to indicate that, in this age of globalization, the problems of one population can quickly become the problems of all. The same is true in the area of behavioral health, where we see knowledge, beliefs, and behaviors traversing international borders in new and unexpected ways. In this course, the instructor will discuss behavior change through the lens of three populations with which he is intimately familiar: community health workers in the underdeveloped southeastern region of Haiti, educators in Tanzania, and newly arrived refugees in inner-city Philadelphia. Each of these groups faces unique challenges and brings new perspective to the concepts of health and behavior change as they relate to our lives in the U.S. They may even offer new solutions that can benefit us all.
