The Expectation-Confirmation Theory (ECT) asserts that consumers’ intention to repurchase a product or service is significantly influenced by their prior experience with that product or service (Anderson & Sullivan 1993; Oliver
1980). Lower expectation and/or higher perceived performance may lead to a greater confirmation, which results in positive influences to customer satisfaction and continuance intention. Reversing the relationship would cause
disconfirmation, dissatisfaction, and discontinuance intention. Confirmation refers to the expectation-performance
discrepancy (Hayashi, Chen, Ryan & Wu, 2004). Bhattacherjee (2001) suggests that the IS users’ continuance decision is similar to consumers’ repurchase decision because both decisions (1) follow an initial (acceptance or purchase) decision, (2) are influenced by the initial use (of IS or product) experience, and (3) can potentially lead to an ex-post reversal of the initial decision.
