First-Line and Middle Manager IT Usage Intention: A Comparison of TAM, TRA and TPB

In this study, the appropriateness of TRA, TPB and TAM to predict the first-line and middle manager IT usage intention is compared due to the gap found in prior research and the practical need for more information in this area. Hierarchical regression analysis is conducted with the sample of 156 first-line and middle managers distributed in 73 companies. The results show that TRA is most appropriate to explain the first-line and middle manager IT usage intention compared with TPB and TAM, as both the TPB and the TAM can not yield an increase in the predictive ability over the TRA. Attitude is significant predictor of the first-line and middle manager IT usage intention, while the subjective norm, perceived behavioral control, perceived usefulness and perceived ease of use are not significant predictors of the first-line and middle manager IT usage intention.
