Symposium - Where Are We in Running Health Communication Interventions for Behavior Change?
Reflections from Work in a Dozen Countries over 25 Years
A native of Nepal, Rajiv N. Rimal, PhD, is a Professor at the Johns Hopkins Bloomberg School of Public Health and a scholar in health communication, social norms, and behavior change. For more than 25 years, his research has examined how communication, social influence, and cultural context shape health behaviors and how theory can be translated into effective interventions. His work has spanned more than a dozen countries and addressed HIV prevention, maternal and child nutrition, anemia, vaccination, reproductive health, violence against women, and other major global health challenges.
Dr. Rimal is the author of the Theory of Normative Social Behavior, which explains how people's perceptions of what others do and approve of influence their own behavior. His research combines communication theory with epidemiology, behavioral science, and implementation research, with a strong emphasis on translating evidence into programs that can improve health.
He has led major international research initiatives in India, Ethiopia, Nigeria, Nepal, and other settings, working closely with local researchers, communities, governments, and implementing organizations. His scholarship has also increasingly examined how knowledge and theory move across cultures, challenging the traditional assumption that health communication theories developed in the West can simply be exported elsewhere. Through this work, he advocates for a more reciprocal global exchange in which insights from diverse settings contribute to and reshape the theories that guide health communication worldwide.
