It's all about attitude: revisiting the technology acceptance model

We expanded Davis et al.'s technology acceptance model (TAM) by considering both the affective and the cognitive dimensions of attitude and the hypothesized internal hierarchy among beliefs, cognitive attitude, affective attitude and information systems (IS) use. While many of the earlier findings in TAM research were confirmed, the mediating role of affective attitude between cognitive attitude and IS use was not supported. Our results cast doubts on the use of the affective attitude construct in explaining IS use. Meanwhile, we found that cognitive attitude is an important variable to consider in explaining IS usage behaviors. Our results suggest that attitude deserves more attention in IS research for its considerable influence on the individual and organizational usage of IS. (C) 2003 Elsevier B.V. All rights reserved.
