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