The structure of web-based information systems satisfaction: An application of confirmatory factor analysis

User satisfaction has become one of the most important measures of the success or effectiveness of information systems; however, very little is known about its structure and dimensionality in the web environment. In the current study, five latent variable models were empirically tested and compared to describe the relationships among 21 observable variables concerned with web-based information systems satisfaction. Using data from a sample of 5 15 university students, a second-order model was retained based on statistical and theoretical criteria. At the first-order level were six highly interrelated primary factors; understandability, reliability, usefulness, access, usability, and navigation. These six factors were explained by two interrelated second-order factors of web information satisfaction and web system satisfaction. Overall, the model provides a good-fit to the data and is theoretically valid, reflecting logical consistency. Implications of the current investigation for practice and research are provided.
