Incorporating commitment theory from social psychology and management science literature, this paper proposes a IS continuance model that explains users’ intention to continuously use IS technologies. We argue that users’ intention to continue using a IS technology (i.e., IS continuance) is determined by their commitment to that specific technology and moderated by the brand-specific technology product. Three dimensions of technology commitment, affective commitment, continuance commitment, and normative commitment, are identified to formulate a research model. The hypotheses are empirically tested and the model accounts for 70.9% of variances. Results and contributions of this research-in-progress model are discussed.
