Perceived usefulness, perceived ease of use, and user acceptance of information technology

Valid measurement scales for predicting user acceptance of computers are in short supply. Most subjective measures used in practice are unvalidated, and their relationship to system usage is unknown. The present research develops and validates new scales...
