Interpersonal influences refer to the degree to which employees believe that colleagues and superiors think they should use an application. Interpersonal influences manifest as and travel via word-of-mouth. When the consequences of adopting a new application are unclear, people rely on their social network to help make a decision. [43]. Furthermore, using mobile health applications in the workplace is a form of public consumption and tends to be highly influenced by others as well [44]. Notably, we argue that supervisors may have a positive impact on adoption as they can serve as role models. Middle and lower level management with more frequent interaction with employees can promote applications by displaying interest, commitment, and active participation. Moreover, software developers can enhance the effect of interpersonal influence by equipping applications with “Social Web” (Web 2.0) features that provide a platform within the application for the interactive exchange of experiences. We argue that interpersonal influences will have a greater influence in later phases of adoption, when there are enough users for word-of-mouth to have a meaningful impact. Accordingly, we propose that interpersonal influences have a positive influence on normative beliefs.
