Mesfin A. Bekalu

Research Scientist

Department of Social and Behavioral Sciences

I am a research scientist in the Lee Kum Sheung Center for Health and Happiness, Department of Social and Behavioral Sciences, Harvard T.H. Chan School of Public Health. I hold a PhD in Social Sciences from the University of Leuven in Belgium. Broadly, my research area is health communication. I am interested in investigating the intended and unintended effects of media and messages on health-related attitudes, beliefs and behaviors. This involves studying the effects of campaign materials designed and produced for strategic communication purposes and delivered through different media (print, broadcast and the Internet) as well as the unintended harmful and/or beneficial effects of media and messages on health-related outcomes in secular communication contexts. My studies draw on different communication and behavioral theories that advance our understanding of health-related behavior change processes.

Research:

My current research focuses on social media, taking a two-pronged approach on the role of these ubiquitous platforms in population health. The first approach focuses on the link between social media use behavior and well-being (physical, mental and social well-being), and the various individual, social and contextual factors that moderate and mediate the link. In this approach, I take a more holistic and innovative perspective to conceptualize, define and measure individuals’ social media use experiences and concomitant health and well-being outcomes. The second approach investigates the use of social media as a tool for health promotion and disease prevention interventions. In this effort, I try to employ concepts and strategies from other social science disciplines such as political science, marketing and behavioral economics to fully understand the potential and limits of using social media for health interventions. Communication inequalities and the role of communication in abating and/or exacerbating health disparities are central in my research program on social media and well-being. Methodologically, my research employs a mixed-method approach with a strong quantitative focus.
