摘要
Zusammenfassung Das Mentalisierungskonzept ist sowohl in der Praxis als auch der Wissenschaft breit rezipiert worden, u.a. wegen seiner hohen klinisch-therapeutischen Relevanz. Um dieses Konzept der empirisch-quantifizierenden Forschung zuganglich zu machen ist u.a. der Reflective Functioning Questionnaire mit 8 Items (RFQ-8) entwickelt worden, der 2 Skalen (Unsicherheit uber mentale Zustande bzw. Hypomentalisieren und Gewissheit uber mentale Zustande respektive Hypermentalisieren) umfasst. Wahrend erste, methodisch jedoch kritisch zu bewertende teststatistische Untersuchungen dieses Selbstbeurteilungsverfahren weitgehend positiv beurteilen, stehen Analysen zur deutschen Version aus. In dieser Studie wurde die deutsche Version des RFQ-8 erstmals an einer gro ss en Allgemeinbevolkerungsstichprobe (n=2477) psychometrisch evaluiert. Diverse konfirmatorische und explorative Faktorenanalysen zeigten, dass die ursprunglich vorgeschlagene 2-Faktoren-Losung fehlspezifiziert ist; vielmehr ist davon auszugehen, dass der RFQ-8 ein eindimensionales Konstrukt abbildet. Nach Ausschluss von 2 teststatistisch ungenugenden Items zeigte die Skala mit 6 Items (RFQ-6) eine hohe interne Konsistenz (McDonald's omega =0,88) sowie substantielle Rangkorrelationen mit Depressivitat, Angstlichkeit und korperlichen Beschwerden. Wir diskutieren, warum der Einsatz des RFQ-8 in Klinik und Forschung angesichts der teststatistischen Mangel sehr kritisch zu sehen ist, insbesondere was die Erfassung von Hypermentalisieren angeht. Abstract The concept of mentalization has attracted broad clinical and scientific interest, particularly because of its high clinical and therapeutic relevance. To make this concept accessible for empirical research, the 8-item Reflective Functioning Questionnaire (RFQ-8) was developed, which comprises 2 subscales tapping into uncertainty about mental states (or hypomentalizing), and certainty about mental states (i.e. hypermentalizing). Although first psychometric examinations have evaluated the RFQ-8 positively, these findings must be interpreted with caution for methodological reasons. The aim of this study was the psychometric evaluation of the German version of the RFQ-8 in a large general population sample (n=2477). Various confirmatory and exploratory factor analyses indicated that the originally introduced 2-factor solution is mis-specified. Instead, the RFQ-8 seems to cover a unidimensional construct. Having excluded 2 items due to their insufficient psychometric qualities, the 6-item measure (RFQ-6) showed high internal consistency (McDonald's omega =0,88) as well as significant rank correlations with depression, anxiety and bodily complaints. Considering the psychometric limitations of the RFQ-8, its use in clinical routine and research should be viewed very critically, particularly with respect to its ability to assess hypermentalizing.
