Abstract
Zusammenfassung.Theoretischer Hintergrund: Metakognitionen wird für das Verständnis verschiedener psychischer Störungen eine wichtige Rolle beigemessen. So kann z.B. übermäßiges Sorgen durch Metakognitionen ausgelöst und aufrechterhalten werden. Fragestellung: Ziel dieser Arbeit war die systematische psychometrische Untersuchung der deutschen Kurzform des Metacognition Questionnaire (MKF-30). Methode: Mittels einer Teilstichprobe (N = 1168) wurde explorativ die Faktorenstruktur des MKF-30 ermittelt. Die ermittelte 5-Faktorenstruktur wurde anschließend konfirmiert (Teilstichprobe 2: N = 1155). Zur Konstruktvalidierung wurden Angst- sowie ein Depressionsfragebogen eingesetzt. Ergebnisse: Es ließen sich die fünf Faktoren des englischen Originals replizieren und konfirmieren. Die Analysen der Itemkennwerte sowie der konvergenten Validität lieferten insgesamt gute Ergebnisse. Schlussfolgerungen: Der MKF-30 kann vorläufig als ein reliables, valides und ökonomisches Instrument zur Erfassung von Metakognitionen angesehen werden.
Abstract.Background: Metacognitions are likely relevant for a number of mental disorders. For example, excessive worrying can be elicited and maintained as a consequence of metacognitions. Objective: This study was aimed at the validation of the German short form of the Metacognitions Questionnaire (MKF-30). Methods: Using a subsample (N = 1168) we explored the factor-structure of the MKF-30. We then confirmed the resulting five-factor-structure using the remaining subsample 2 (N = 1155). We used other anxiety and mood questionnaires to analyse the construct validity. Results: The five-factor-structur of the English orginal was replicated and confirmed. Item properties and convergent validity were good. Conclusions: The MKF-30 can provisionally be considered a reliable, valid and an economic instrument for the assessment of metacognitions.
