5. Equivalence of the IPQ-R: Methodical approach
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).
5.1 General considerations and overview
The objective of Research component 2a and 2b was to establish the IPQ-R baseline models for Turks residing in Turkey and Turkish migrants residing in Germany, respectively. This was done by means of two separate confirmatory factor analyses. The Research components 3a to 3d examined the conceptual, semantic, operational and measurement equivalence of the IPQ-R by means of a mixed-method approach. For conceptual and semantic equivalence it comprised systematic literature reviews and qualitative interviews. Operational equivalence was only examined by systematic literature reviews. Measurement equivalence was studied by multi-group confirmatory factor analysis.
An overview of the two empirical research components and the different methods applied in each of them along the argumentation in Chapter 4 is presented in Tab. 5. ← 47 | 48...
