Understanding Tablets Adoption Intentions: A Two-Models Comparison
In the absence of an obvious model to interpret the information technology (IT) adoption phenomenon, it is recommended to test the explanatory and predictability powers of multiple models before making conclusions about which model best explains and predicts the adoption of a specific IT system in a particular context.This study compares the results of applyingthe Theory of Reasoned Action (TRA) and the Technology Acceptance Model (TAM) to elucidate tablets adoption patterns by young individuals in an Arab culture. In addition to their original constructs, the two models examined attachment motivation, personal innovativeness, and perceived enjoyment.Compared to the TRA model, the fitted TAM model has a greater explanatory power, as it explains higher percentages of the variance in attitudes and intentions. Perceived enjoyment emerges as the strongest determinant of intentions, followed by perceived usefulness and attitude. In addition, attitude appears to influence the intentions to adopt the tablet much less that what the two models postulate.
