A Review on the Relationship Between New Variables and Classical TAM Structure

Integration of different theories and expansion of research areas are the main trends in the research domain of IS adoption. Classical TAM structure has been largely expended by newly added variables. Prior studies [1] have analyzed relationships among variables in TAM and found the stability of classical structure, but what about relationships between new variables and classical structure? We selected 30 articles from the main international journals for analyses. It is found that, SE SN and PBC are used mostly in extended TAM. The relations between SE, PBC and TAM are consistently significant, but the integration of SN into TAM is not so ideal. In our review scale, this relation is inconsistent. Other variables and relations are also discussed in this article. The conclusions of this article will provide guidance for future researches about extended TAM model building.
