Abstract: | To provide more specific explanation of consumers' purchase intention on the Internet, this study expanded the original theory of planned behavior (TPB) by decomposing belief constructs and by including interdependency terms between salient beliefs. The findings of this study supported the existence of interdependencies between salient beliefs in TPB. Also, the decomposition of attitude components is expected to provide on‐line retailers with more clear‐cut information about customers' evaluative criteria for e‐tailers when they make a purchase decision on the Internet. © 2005 Wiley Periodicals, Inc. |
