Toward a Model of Word-of-Mouth in the Health Care Sector

An important source of health information is word of mouth (WOM). Nevertheless, a model describing WOM in the health care sector does not exist. The aim of this paper is to contribute to research by providing concrete suggestions for a model of word of mouth in the health care sector. A conceptual framework comprising the theory of cognitive dissonance, the theory of the strength of weak ties, and the theory of perceived risk are used as a theoretical anchor. In order to gain a more precise knowledge of WOM in the health care sector, a literature review of leading health care journals is conducted. The findings are summarized in the form of a model proposal describing the creation, spread, and impact of WOM in the health care sector. As the model summarizes the current WOM literature, it seems to be a good starting point for further research by scholars. The paper also helps practitioners to better understand WOM and integrate the WOM aspects described into their daily work.
