What is important for hearing aid satisfaction? Application of the expectancy-disconfirmation model.

Background: Between 68.1-89.5% of clients report that they are satisfied with their hearing aids. Two variables that are thought to contribute to dissatisfaction with hearing aids are product performance, and a mismatch between performance and client prefitting expectations about hearing-aid performance (i.e., disconfirmation). A focus on variables related to satisfaction is relevant to improving hearing rehabilitation services.
