4. A consequence of complex models and measures? [T]he measurement of satisfaction seems in a state of disarray […] The diversity of words used in five-point or seven point semantic differentials or Likert-type rating scales is simply astonishing […] Of the 112 studies that measure satisfaction […] only twelve studies employ standardized questionnaires.

Hornbæk2006: Another indication of the disarray is in the limited use of standardized questionnaires and the few studies that use measures that directly build upon earlier work. Of the 112 studies that measure satisfaction, 29 (26%) refer to previous work as a source for the questions. Among those, only twelve studies employ standardized questionnaires for measuring some kind of satisfaction.
