A confirmatory factor analysis of the user information satisfaction instrument

The structure and dimensionality of the user information satisfaction (UIS) construct is an important theoretical issue that has 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 components. Based on a sample of 224 respondents, confirmatory factor analysis is used to test alternative models of underlying factor structure and assess the reliability and validity of factors and items. The results provide support for a revised UIS model with 4 first-order factors and one 2nd-order (higher-order) factor. To cross-validate these results, 2 data sets are examined, including the original Baroudi and Orlikowski (1988) data, to assess the revised UIS model. The results show that the revised model provides better model-data fit in all 3 data sets. Thus, the evidence supports the use of: 1. the 13-item instrument as a measure of an overall UIS, and 2. four component factors for explaining the UIS construct.
