Culture And Student Samples As Moderators Of Continued IT Usage: A Meta-Analysis Of IS Continuance Literature

Abstract

The benefits from ICT investments materialize through sustained usage rather than initial acceptance. Hence, the amount of research on continued IT usage (IS continuance) employing the Expectation-Confirmation Model (ECM) has been increasing steadily in recent years. In this body of literature, empirical results regarding the correlations between the key constructs of ECM have not been entirely consistent. Thus, we conduct a meta-analysis of prior IS continuance literature to examine whether the flux in the results can be explained by the presence of moderating effects. First, we investigate whether the cultural context of the empirical study or the use of student samples has influenced the results. Second, we examine whether including perceived ease of use in the ECM has received consistent empirical support. The results demonstrate that both cultural context and student samples potentially act as moderators, and thus have caused the flux in the empirical results. Furthermore, the results show that perceived ease of use is a viable extension to ECM.
