Abstract: Information systems (IS) researchers have long been interested in understanding why some people accept a certain computing technology but others are not. Communication media researchers also examined how and why people choose to use one communication media rather than another. With the increasing individual use of CMC technology for social interaction in online context, the phenomenon that many users have adopted and use multiple applications of a communication technology continuously cannot be well explained by previous theories. Driven by business and academic needs, this research aims to examine users’ different behaviors and preferences in using multiple similar applications, with the case of instant messaging technology. The proposed model may shed light on 1) he cognitive, affective, conative antecedents of a user’s choice among alternative IMs in post-adoptive context 2) the roles that different types of behavioral beliefs play in determining a user’s choice among alternative IMs in post-adoptive context? 3) the competitive effects of other IMs on a user’s choice among alternative IMs in post-adoptive context. The results show that a user’s inclusive choice among alternative IMs is determined by subjective norm, satisfaction and choice intention. Subjective norm and satisfaction also influence choice behavior indirectly through attitude and choice intention. In addition, ties construction utility and identity construction utility developed in this study are significant predictors to a user’s satisfaction toward the technology. Implications of the results are also discussed.
