Testgüte einer deutschen Version des Mehrdimensionalen Perfektionismus Kognitions-Inventars (MPCI-G)
Abstract
Zusammenfassung. Gegenstand der vorliegenden Arbeit ist die Entwicklung einer deutschsprachigen Version des Mehrdimensionalen Perfektionismus Kognitions-Inventars (MPCI-G [G = German]). In einer ersten Studie wurde die faktorielle Validität des MPCI-G überprüft. Auf Basis der Ergebnisse aus Studie 1 wurde der MPCI-G revidiert (MPCI-G-R). In Studie 2 wurden die Reliabilität, faktorielle und Konstruktvalidität des MPCI-G-R untersucht. Die Ergebnisse aus konfirmatorischen Faktorenanalysen, Korrelations- und multiplen Regressionsanalysen sprechen für die Reliabilität, faktorielle und Konstruktvalidität der 3 (korrelierten) Dimensionen perfektionistischer Kognitionen: Personal Standards (PSK), Concern over Mistakes (CMK) und Pursuit of Perfection Kognitionen (PPK). Unter anderem fanden sich differentielle Zusammenhänge der 3 Dimensionen mit dispositionellem Perfektionismus (Perfectionistic Strivings und Concerns), Affekt (schlechte Stimmung und Unruhe), Depressivität und der Zielsetzung für eine bevorstehende Prüfungsphase. Die reliable und valide multidimensionale Erfassung perfektionistischer Kognitionen, die zwischen eher positiven (PSK) und negativen Dimensionen (CMK und PPK) differenziert, stellt eine wertvolle Ergänzung zur Erforschung des dispositionellen Perfektionismus dar, welche das Verständnis dafür fördern kann, wie Dimensionen des dispositionellen Perfektionismus mit psychischem und physischem Wohlbefinden zusammenhängen.
Abstract. The present article describes the development of the German version of the Multidimensional Perfectionism Cognitions Inventory (MPCI-G). In an initial study we investigated the factorial validity of the MPCI-G. Based on the results of Study 1, the MPCI-G was revised (MPCI-G-R). In Study 2 we investigated the reliability, factorial validity, and construct validity of the MPCI-G-R. Results of confirmatory factor analyses as well as correlational and multiple regression analyses supported the 3-factorial structure of the 3 intercorrelated dimensions of perfectionistic cognitions assessed by the MPCI-G-R: personal standards (PSK), concern over mistakes (CMK), and pursuit of perfection cognitions (PPK). Thereby, the three dimensions showed differential associations with dispositional perfectionism (strivings and concerns), affect (unpleasant mood and tense arousal), depression, and goal setting for an imminent examination period. The reliable and valid multidimensional assessment of perfectionistic cognitions, differentiating between positive (PSK) and negative dimensions (CMK and PPK), is a useful supplement to the assessment of dispositional perfectionism in that it can promote the understanding of how dimensions of dispositional perfectionism are associated with psychological and physiological well-being.
