Software Evaluation and Choice: Predictive Validation of the Technology Acceptance Instrument

Information technology (IT) researchers repeatedly insist upon the rigorous validation of measuring instruments, yet most IT instruments remain at an early stage of development. The Technology Acceptance Model indicate that perceived usefulness and ease of use will influence an individual's intentios to use an information technology. This research introduces a criterion variable that measures intentions as a choice among sevearl alternatives with subjects actually expecting to use their choice.
