AbstractBased on an augmented Technology Acceptance Model (TAM), this paper examines the influence of computer attitude and self-efficacy on IT usage behavior. Computer attitude and self-efficacy were explicitly incorporated in the research model as external variables affecting perceived usefulness and perceived ease of use, the two key factors influencing the IT usage behavior in the original TAM. Data collected from 360 business students were tested against the model using LISREL The results show that computer attitude has a significant, positive effect on perceived usefulness and perceived ease of use. Computer self-efficacy, on the other hand, has a relatively small, but negative, effect on perceived usefulness and no significant effect on perceived ease of use. The addition of computer attitude and self-efficacy into the TAM greatly improves the explanatory power of the model on the variance of perceived usefulness, which is again found to be a significant factor affecting the behavioral intention of using an IS/IT. Implications of the findings for research and practice are discussed.
