| Abstract | When respondents fail to use response scales of survey questionnaires as intended, latent variable modeling of data can produce disordered category thresholds. The objective of this paper is to show the usefulness of the Rasch modeling features to explore different ways of collapsing categories so that they are properly ordered and fit for further analysis. Twenty-four items of a survey questionnaire with a response scale composed of six categories were analyzed. Among the many strategies explored and those suggested as guidelines by researchers, one provided much better results. It appears that suggested guidelines regarding how to collapse categories are just guidelines and should not be applied blindly. As a matter of fact, they should be related to each context.
