Abstract
E-health (eHealth) is an emerging field of health communication encompassing medical informatics, public health, and business where health information and services are exchanged through electronic processes. The current leading researchers in e-health include: Dr. Gunther Eysenbach from University of Toronto on health information and decision-making; Dr. David Gustafson from University of Wisconsin, Madison on interactive support systems; The Pew Internet and American Life Project on chronicling e-health use; Dr. Neil Coulson from University of Nottingham on online support group communication, and Dr. Elizabeth Murray from University College London, who develops online treatments. This entry summarizes research on e-health behaviors: seeking health information online, the impact of patient-to-patient communication on health, and receiving treatment online. Future directions for research on e-health behaviors include exploring the disadvantages of online support groups, research on minority populations, development of online randomized controlled trial methodology, and longitudinal research examining e-health behaviors over time.
