A Rasch Re-Analysis of the Partnership Questionnaire

Abstract

The Partnership Questionnaire (PFB) is used favorably in the German language area to measure partnership quality. The goal of the present study is to re-analyze the subscales of the PFB ( Conflict Behavior, Tenderness, Communication ) via the Rasch model. Polytomous and dichotomous Rasch models were calculated in a population sample ( N = 1,123) and a student-based cross-validation sample ( N = 250) for the three subscales of the PFB. Final models were chosen based on several fit criteria. Good to very good model fit was obtained with symmetrical (Conflict Behavior) or nonsymmetrical (Tenderness, Communication) dichotomously collapsed categories. After adapting the instruction and dichotomizing the categories, the PFB can be used as a checklist ( PFB-checklist ). An additional cross-validation is needed to substantiate the obtained results.
