Recent studies in the US and other developed countries have demonstrated that customer satisfaction is a key element for a profitable business. Much of this work has been done in developed nations. We wanted to know if a foreign-developed customer satisfaction model will hold in a developing South American nation having its own culture and going through basic stages of economic development. In particular, the present study provides an exploratory test of the validity of a general model that considers both confirmation of expectations and congruence of desires as drivers of satisfaction (Spreng and Olshavsky 1993) in Chile, using structural equations modeling.
