Abstract

The measurement scales for the perceived usefulness and perceived ease-of-use constructs introduced by F.D. Davis (1989) become widely used for forecasting user acceptance of emerging information technologies. An experiment was conducted to examine whether grouping of items caused artifactual inflation of reliability and validity measures. We found support for our hypothesis that the reliability and validity stemmed not from item grouping but from the constructs of perceived usefulness and perceived ease-of-use being clearly defined, and the items used to measure each of these constructs clearly capturing the essence of the construct
