Re-Examining Perceived Ease of Use and Usefulness: A Confirmatory Factor Analysis

Recently, Adams, et al. (1992) presented the results of two studies designed to replicate previous work by Fred Davis (1989) regarding perceived usefulness, ease of use, and their in- fluence on the usage of information technology. Specifically, these authors sought to: (1) evaluate the psychometric properties of the ease of use and usefulness scales, and (2) empirically examine the relationship between the constructs (or traits) of usefulness, ease of use, and reported levels of usage.
