Predicting users' Intention to Continue Mobile Internet Services Usage : The Integration of Habit into the Expectation-Confirmation Model

The expectation-confirmation model (ECM) based on expectation-confirmation theory is currently the dominant referent theoretical framework for explaining continued usage of information systems. Along with ECM, "habit" construct meaning automatic behavior tendencies has also recently been incorporated into IS research. This study, based on these concepts, made an attempt to incorporate habit into ECM in the continued mobile internet services usage context. For this purpose, we have developed and empirically validated a research model comprising continuance intention, satisfaction, and such post-adoption beliefs as confirmation, perceived usefulness, perceived ease-of-use, and habit. We performed a survey for 250 university students who resides in J. province. Our findings support the argument that confirmation and perceived usefulness play an important role in explaining users' satisfaction with using mobile internet services. It also support that perceived usefulness, satisfaction, and habit are crucial determinants of users' intention to continually using mobile internet services. But perceived ease-of-use was found to have no relationships with both satisfaction and continuance intention. Implications of these results are discussed.
