ABSTRACT: The key phenomenon studied in this paper is continued system use (CSU). Realizing that the continuing use of a system is not a one-time event, but rather unfolds longitudinally, we examine how the relationships between CSU and its various antecedents evolve over time. We focus on two behavioral antecedents – habit and continuance intention to use the system. While the latter has been studied extensively, there is relatively limited literature on the former. We examine how relationships between habit and its various determinants evolve temporally. We also theorize the evolution of relationships between continuance intention and its antecedents. We draw upon the tripartite model of attitude and the theory of interpersonal behavior to examine CSU. Further, grounding on prior psychology literature on habit, we specifically hypothesize the interaction effect of habit and intention on CSU. In contrast to the negative moderation effect of habit proposed in the information systems (IS) literature on the relationship between intention and system use, we posit a positive interaction effect. We extend the conceptualization and empirical evaluation of CSU by examining voluntary use of a utilitarian system over not one but five post adoption time periods. We collect survey data on the use of a higher education information system from students in a university located in central Germany. We use partial least squares based structural equation modeling and multiple group analysis to analyze our data. Our results provide modest support for the proposed research model. Our results suggest that the interaction effect between habit and intention is positive and increasing over time. Theoretical and pragmatic implications of study findings are discussed.
