The role of task-technology fit as users' motivation to continue information system use

In this study, we extend and combine the post-acceptance model (PAM), proposed by Bhattacherjee [Bhattacherjee, A. (2001). Understanding information systems continuance: An expectation-confirmation model. MIS Quarterly, 25(3), 351-370], with aspects of Goodhue and Thomson's theory of task-technology fit (TIFF). The original PAM emphasizes cognitive beliefs and user feelings as factors that may influence a person's intention to continue to use an information system (IS). The variables added from TTF are task-technology fit and utilization. The sample consists of data that measure use and use-related aspects of an e-learning tool among university college teachers. Using structural equation modeling, results indicate that variables from TTF as well as variables from PAM explain users' IS continuance intention. As a result of these findings, we propose the existence of two different and autonomous paths from the independent variables to the dependent variable of IS continuance intention. These two paths are: a work system-centric path through utilization of the information system, and an IT-centric path through user satisfaction. (C) 2009 Elsevier Ltd. All rights reserved.
