Previous research suggests that an eventual information technology (IT) success depends on both its initial adoption (acceptance) and subsequent continued usage (continuance). Theory of planned behaviour (TPB) has been successfully used to predict users' acceptance of IT. Yet, this theory has not been applied to the context of continuance of IT. This paper examines post-adoption cognitive beliefs and factors influencing one's intention to continue using (continuance) electronic services (e-services). Decomposed theory of planned behaviour (DTPB) is adapted from social psychology and integrated with theoretical and empirical findings from prior information systems (IS) usage research to theorize a model of e-service continuance. Specifically, the research model decomposes the perceived behavioural control components of TPB into Internet self-efficacy and perceived controllability, the subjective norm component into social influences and interpersonal influence, and the attitude component into perceived usefulness, perceived playfulness, and perceived risk. Nine research hypotheses derived from this model are empirically validated using a field survey of Web-based tax filing service users. The results suggest that users' continuance intention is determined by Internet self-efficacy and satisfaction. Satisfaction, in turn, is jointly determined by interpersonal influence, perceived usefulness, and perceived playfulness.
