The paper reports findings of research into the dynamics of customer satisfaction formation amongst fruit producers and their distribution channel(s), within the economically important northern Victorian (Australia) fruit industry. The paper suggests reasons why previous approaches to the issue of satisfaction in channel member relationships, which typically utilize constructs of 'economic' and 'non-economic' satisfaction, may usefully be supplemented by application of the 'disconfirmation of expectations' model. The research actually tests a modification of the traditional disconfirmation model that incorporates dimensions of 'outcome' and 'process' at the levels of expectations, performance and disconfirmation-a 'dualistic' model. This had previously been tested only in a radically different business-to business-context, that of advertising creative services. The findings suggest that satisfactory measurement of growers' expectations can be achieved. They also suggest that the disconfirmation model does appear to apply in this previously untested service context, whether unitary measures of expectations and performance, or the dualistic interpretation of expectations/performance, are utilized.
