Expectation-Confirmation Theory (ECT) was proposed by Oliver [1980] to study consumer satisfaction and repurchase behavior. The ECT theory states that consumers firstly form an initial expectation prior to purchase, and then build perceptions about the performance of the consumed product/service after a period of initial consumption. Next, consumers will decide on their level of satisfaction based on the extent to which their expectation is confirmed through comparing the actual performance of the product/service against their initial expectation of the performance. Consequently, satisfied consumers will form repurchasing intentions. Similarly, when customers have confirmed their expectation that an e-commerce website is trustworthy, they will be more motivated to repurchase from the same e-commerce website.
