Psychometrically Relevant Differences between Source and Migrant Populations

Series:

Patrick Brzoska

Psychometrically relevant population differences may limit the transferability of research instruments between migrants and their source population and may contribute to a low performance of quantitative questionnaires. Based on a review of existing taxonomies, this book develops a comprehensive analytical framework of equivalence that can serve multiple purposes. It allows to examine psychometrically relevant population differences, it can assist in the re-adaptation of questionnaires and it is a valuable tool for cross-group comparative research. The application of the framework is illustrated through the examination of equivalence of the Revised Illness Perception Questionnaire (IPQ-R) between chronically ill Turks residing in Turkey and Turkish migrants residing in Germany.

5. Equivalence of the IPQ-R: Methodical approach

Extract



In this chapter, the analytical framework of questionnaire equivalence developed in Research component 1 and outlined in Chapter 4 is used to study psychometrically relevant differences between Turks residing in Turkey and Turkish migrants residing in Germany (Research components 2 and 3).

In the following, first an overview of the mixed-method approach chosen for this study is presented. Second, the methods used for the establishment of the IPQ-R baseline models in Turks residing in Turkey and Turkish migrants residing in Turkey (Research components 2a and 2b) are described. Third, the different methodical approaches chosen for the examination of the conceptual, semantic, operational and measurement equivalence of the IPQ-R are illustrated (Research components 3a-d).
