Information Systems Use: Construct conceptualization and scale development

摘要

Information Systems Use (ISU) is an essential part of the human behaviors in utilizing computers in organizations. The construct has been widely used to measure IS adoption or IS success. However, few studies attempt to understand ISU in a job and organizational setting where employees use various types of IS for different tasks. To better understand ISU, it is necessary to contextualize the construct in users’ overall work related activities. We classified the overall IS/IT use in an organization into three different types of IS; Information Reporting Systems (IRSs), Decision Support Systems (DSSs), and Group Support System (GSSs). Based on this classification, we developed four items for each type of ISU behaviors. The resulting ISU instrument was tested using a dataset of 231 responses collected in a survey. Both exploratory factor analysis and PLS are employed to successfully establish reliability, convergent/discriminate validity, and predictive validity. The contribution of this research is to provide better and more robust measurements for the ISU construct, which should help to lay a firmer foundation for further research on IS success.
