An extended version of the technology acceptance model (TAM) is applied to study hospital Web sites, one specific area of e-health. In a review of literature, five significant factors from TAM research are identified that are logically related to e-health sites from the user’s perspective: usefulness, ease of use, trust, privacy, and personalization. All five factors emerged in the data analysis of 30 participants using a hospital Web site. We discuss the implications of this study for guiding development of effective patient-centered e-health.
Using proven research approaches such as TAM and UCD to investigate patients’ adoption of e-health can provide important insights. “The TAM postulates that user adoption of a new information system is determined by their intention to use the system, which in turn is determined by their beliefs about the system” (Wang, 2003, pp.335). In online technology adoption, the TAM model highlights the importance of trust, usefulness, and ease of use from the user’s point of view (Gefen et al., 2003; Gefen & Straub, 2000; Perea y Monsuwe et al., 2004; Wang et al., 2003). More specifically, research using TAM in e-commerce has found that trust, privacy, and user perceptions of technology are central elements of online technology adoption (Gefen et al., 2003; Gefen & Straub, 2000; Perea y Monsuwe et al., 2004; Wang et al., 2003).
