Health Communication Overview

Principles

Definition

Health communication is an interdisciplinary field of study and practice focused on the role of human communication in health outcomes and healthcare contexts. It investigates the creation, dissemination, and reception of health-related information across various levels, from interpersonal interactions to mass media and digital platforms, examining the interplay of messages, channels, and contexts. The field seeks to inform, persuade, and empower individuals and communities, ultimately aiming to improve health literacy, promote healthy behaviors, and enhance public health initiatives.

Key Figures

Theory-driven Patient Communication era

John E. Ware [1] anchored patient-centered measurement during this era, with Tufts University [3] as a major institutional base. A key contribution is the MOS 36-item short-form health survey (SF-36) [6], whose conceptual framework and item selection defined standardized health-status outcomes crucial for evaluating communication interventions in clinical encounters. Karen Glanz [2] collaborated with the University of Minnesota [4] as a central hub of health education research during this era, alongside the University of Hawaii System [5] on broader dissemination. Her influential contribution is Health Behavior and Health Education: Theory, Research, and Practice [7], which connected theory-driven models to practical health-education interventions, underpinning risk framing and empowerment approaches in patient communication.

Online Health Information Quality era

Don Nutbeam [1] was associated with the University of Glasgow [3] and the University of Bristol [4] in this era. His key contribution is the 2000 paper Health literacy as a public health goal: a challenge for contemporary health education and communication strategies into the 21st century [7], which framed health literacy as a public health goal and thus underpinned the quality-evaluation and governance efforts in online health information for the era. David W. Baker [2] was associated with Northwestern University [5] and Emory University [6] during this era. His contributions span the papers The meaning and the measure of health literacy [8], Relationship of Functional Health Literacy to Patients' Knowledge of Their Chronic Disease [9], and Shame and health literacy: the unspoken connection [10], which collectively advanced health-literacy measurement [8], connected functional literacy to patients' knowledge [9], and highlighted psychosocial barriers such as shame in health information engagement [10], thereby informing quality metrics and consumer-education approaches for online health information in this era.

Networked Surveillance and Infodemics era

Walter Quattrociocchi [1] is a leading figure in health communication during the Networked Surveillance and Infodemics era, with affiliations at the University of Siena [3] and the University of Oslo [4]. His key contributions include analyses of the COVID-19 social media infodemic [7] and the polarization of the vaccination debate on Facebook [8], which illuminated how online diffusion and echo chambers shape public understanding and demonstrated the need for real-time monitoring and diffusion mapping in infodemic governance. Richard Lester [2] is another central voice in this era, with ties to the University of Toronto [5] and the University of British Columbia [6]. His notable contribution involves the paper Effects of a mobile phone short message service on antiretroviral treatment adherence in Kenya (WelTel Kenya1): a randomised trial [9], illustrating early, scalable mobile-health interventions that informed targeted outreach and adherence-support strategies in networked health communication.
