Health is broadly defined as “a state of complete physical, mental, and social well-being, and not merely the absence of disease or infirmity” (World Health Organization, 1948). Improving the health of individuals or communities is often closely tied to behavior change. Therefore, behavior analysis can complement the work being done in many areas of public health. The current presentation will provide examples of how components of behavior analysis methodology can be applied to interdisciplinary projects in global health, specifically in the areas of infectious disease transmission and nutrition. Suggestions will also be provided as to other areas of public health that could benefit from behavior analytic contributions.
