Using customer satisfaction survey data collected from over 400,000 respondents across 7 different multiunit restaurant and retail brands, a complete examination of response differences between visual and aural surveys will be discussed. Respondents for each of the 7 brands were given the opportunity to respond to a 5 – 8 minute long survey accessing either a self-administered Interactive Voice Recording (IVR) or a website. With this research design and respondent sample, we will discuss differences in demographic profiles, break-off rates, sensitivity to questionnaire length, survey response scores, general item and sensitive question non-response, and response differentiation by survey mode.
