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 for two specific variables, perceived usefulness and perceived ease of use, which are hypothesized to be fundamental determinants of user acceptance. Definitions for these ii variables were used to develop calibration items that were pretested for content validity and and so tested for reliability and construct validity in two studies involving a full of 152 users and four application programs. The measures were refined and stream-lined, resulting in ii six-item scales with reliabilities of.98 for usefulness and.94 for ease of use. The scales exhibited high convergent, discriminant, and factorial validity. Perceived usefulness was significantly correlated with both self-reported current usage (r=.63, Written report ane) and self-predicted time to come usage (r=.85, Study 2). Perceived ease of apply was also significantly correlated with current usage (r=.45, Written report ane) and futurity usage (r=.59, Study 2). In both studies, usefulness had a significantly greater correlation with usage behavior than did ease of apply. Regression analyses suggest that perceived ease of use may actually be a causal antecedent to perceived usefulness, every bit opposed to a parallel, direct determinant of system usage. Implications are drawn for future research on user acceptance.
The editorial objective of the MIS Quarterly is the enhancement and advice of knowledge concerning the development of It-based services, the management of Information technology resource, and the employ, impact, and economics of IT with managerial, organizational, and societal implications. Professional person issues affecting the IS field as a whole are also in the purview of the journal.
Established in 1968, the University of Minnesota Direction Data Systems Research Center promotes research in MIS topics past bridging the gap betwixt the corporate and academic MIS worlds through the events in the MISRC Associates Programme.
