Theories in use (uses and gratifications theory and expectation disconfirmation theory)
The uses and gratifications (U&G) framework is a media use model from mass communications research that pilots the assessment of user motivations of media usage and access. The main purpose of this model is to clarify the reasons that individuals choose a specific medium over alternative communication media and to elucidate the psychological needs that people use a particular vehicle. This model assumes that users are goal-directed in their behavior and are aware of their needs. The framework has been applied to various media, plus newspapers (Elliott & Rosenberg, 1987), radio (Mendelsohn, 2009), and television (Babrow, 1987), cable television (Heeter & Greenberg, 1985), VCR (Cohen, Levy & Golden, 1988), mobile phone (Leung & Wei, 2000), email (Dimmick, Kline & Stafford, 2000), the Internet (Stafford, Stafford & Schkade, 2004), virtual community (Cheung and Lee, 2009)) and social network sites (Cheung & Lee, 2009; Shi, Cheung, Lee, & Chen, 2009). Expectation Disconfirmation Theory(EDT), from Marketing, has now been smeared to the adoption of information technology (e.g., Bhattacherjee, 2001a). In specific, information systems (IS) research has recently shown that expectations about technology can forecast perceived performance, disconfirmation of expectations, satisfaction, and usage continuance intentions (Bhattacherjee and Premkumar, 2004; Hsu, Chiu & Ju., 2004; Susarla, Barua, & Whinston, 2003; Khalifa and Liu 2002; Bhattacherjee 2001b). This is a vital area of research that helps clarify the process of adoption by showing how initial expectations are converted by disconfirmation into satisfaction with a system. EDT is a prominent theory from marketing that can predict and explain consumers’ satisfaction with products or services (e.g., Spreng & Page, 2003; Patterson, Johnson & Spreng, 1997; Oliver, 1980). Recently, EDT has been used to explain users’ information technology satisfaction (Bhattacherjee and Premkumar 2004; Hsu et al., 2004; Susarla et al., 2003; Khalifa and Liu 2003, 2002; Bhattacherjee, 2001a, 2001b).
