Adams et al. (1992) presented the results of 2 studies designed to replicate previous work by Davis (1989) regarding perceived usefulness, ease of use, and their influence on the usage of information technology. To measure the influence of usefulness and ease of use on reported levels of usage, Adams et al. employed structural equation modeling. This technique allows the researchers to analyze a set of latent constructs much like independent and dependent variables in regression analysis. Unfortunately, in this part of the analysis, less-than-satisfactory model fit was observed. Further, inconsistencies within and across the 2 studies regarding the strength of causal influence of Davis' constructs on usage seem to suggest that these relationships may be more complex than previously thought. It as suggested that further analysis of these scales be undertaken to better establish their measurement properties, underlying structure, and stability over various technologies. Such an analysis is presented to provide important information to researchers seeking to statistically test relationships among these variables through structural equation modeling.
