Abstract
Cultural considerations could affect individuals' behaviors, including their technology acceptance. This study analyzes the acceptance of computer technology by 1,088 workers in 56 Arabian organizations to reexamine and compare the theory of planned behavior (TPB), technology acceptance model (TAM), and innovation diffusion theory (IDT). The explanatory power of each theory or model seems lower among Arabian workers, as compared with users in Western, developed countries. The IDT appears capable of explaining workers' technology acceptance better than does TPB or TAM. Perceived behavioral control and subjective norms constitute more important acceptance determinants than does attitude. Both perceived usefulness and perceived ease of use remain significant determinants of attitude and intention; however, considering findings reported by previous research, their total effects are comparable in magnitude and statistical significance. The findings are incongruent with the results of several representative prior studies that examine the same theories and models, which in turn offer several implications from a sociocultural perspective.
