Self-administered survey questionnaires are a primary source of data collection in education and in the social sciences in general. It is often difficult to create a question which will be interpreted in the same way by all respondents and then meet the researcher’s goals. A change of wording can influence the meaning of an item, but it is also possible that there would be no influence at all; it all depends on the changes made. Besides, since the first studies related to items’ wording in survey questionnaires, new measurement models were developed. This is the case notably for measurement models from the Rasch family. The goal of this paper is to illustrate how the developments surrounding a measurement model from the Rasch family, namely Andrich’s model for polytomous data, can be put at contribution to study the relative impact of items’ wording on the responses obtained in survey questionnaires.
