A number of researchers have identified interactivity and presence as potentially important attributes of e-Health applications, because they are believed to influence users to interact with systems in ways that increase commitment, learning, and other desirable responses. This paper reports on the development of brief scales to assess the two concepts, and on use of them with participants in six conditions of a large-scale trial of interventions for breast cancer patients. Overall, the Internet scored very low on both measures. Versions of an integrated system of services (CHESS) scored higher, particularly as conditions added features to different versions of the system. Interventions involving a human Cancer Information Mentor scored highest, though even the Mentor was perceived as more interactive and having more presence when combined with the integrated eHealth system.
