Expectation Confirmation Theory
Expectation confirmation theory
Expectations-confirmation theory posits that expectations, coupled with perceived performance, lead to post-purchase satisfaction. This effect is mediated through positive or negative disconfirmation between expectations and performance. If a product outperforms expectations (positive disconfirmation) post-purchase satisfaction will result. If a product falls short of expectations (negative disconfirmation) the consumer is likely to be dissatisfied (Oliver, 1980; Spreng et al. 1996).
The four main constructs in the model are: expectations, performance, disconfirmation, and satisfaction. Expectations reflect anticipated behavior (Churchill and Suprenant, 1982). They are predictive, indicating expected product attributes at some point in the future (Spreng et al. 1996). Expectations serve as the comparison standard in ECT – what consumers use to evaluate performance and form a disconfirmation judgment (Halstead, 1999). Disconfirmation is hypothesized to affect satisfaction, with positive disconfirmation leading to satisfaction and negative disconfirmation leading to dissatisfaction.
