Web-based information systems satisfaction-Theoretical development and testing of competing models

User satisfaction has been widely used in evaluating the performance of web-based information systems (WIS) since the growth of the World Wide Web. This study aims at investigating the structure and diniensionality of the WIS satisfaction construct. We tested the competing models built upon the web satisfaction model and assessed the psychometric properties of the factors and measuring items using confirmatory factor analysis. Our findings suggested that WIS satisfaction can be explained by a higher-order factor model with six first-order factors (i.e., understandability, reliability, usefulness, access, usability, and navigation) and two correlated second-order factors (i.e., web information satisfaction and web system satisfaction). The model provides a good-fit to the data and is theoretically valid, reflecting the logical or formal consistency. Implications of the current investigation for practice and research are provided.
