The confirmation of the validity and reliability of the UIS model toward the Public Management Information System

The structure and dimensionality of the User Information Satisfaction (UIS) construct is an important theoretical issue that received considerable attention. The acceptance of UIS as a standardized instrument requires confirmation that it explains and measures the user information satisfaction construct and its component. Based on a sample of 670 respondents who participated in dealing with the Public Management Information System (PMIS), this research used a confirmatory factor analysis to test the alternative models of underlying factor structure and assessed the reliability and validity of these factors and items in the PMIS. The result provided a support for a revised UIS model with four first-order factors and one second-order (higher-order) factor in PMIS. To cross-validate these results, the author reexamined two prior data sets. The results showed that the revised model provides better model-data fit in all three data sets.
