Abstract
Selbstbeschreibungsinstrumente sind anfällig für Antwortverzerrungen. Die vorliegende Arbeit schätzt die Sensitivität und Spezifität des Verhaltens- und Erlebensinventars (VEI), der deutschen Fassung des Personality Assessment Inventory, in der Erkennung negativer Antwortverzerrungen. Es werden die Ergebnisse von zwei Stichproben berichtet: (a) 25 experimentelle Simulanten bearbeiteten das VEI, das Beck Depressions-Inventar II (BDI-II) und den Strukturierten Fragebogen Simulierter Symptome (SFSS). (b) 95 Probanden, die wegen psychiatrischer und neurologischer Störungen begutachtet wurden, bearbeiteten den Word Memory Test (WMT), den SFSS, das VEI und in 44 Fällen auch das BDI-II. Die Validitätsskalen des VEI identifizierten 72 % der experimentellen Simulanten, der SFSS sogar 92 %. Bei der Gutachtenpopulation wurden 62 % der nach den Kriterien von Slick, Sherman & Iverson (1999) als wahrscheinlich simulierend klassifizierten Personen entdeckt. Nach diesen Befunden bedürfen die Validitätsskalen des VEI im deutschen Sprachraum weiterer Untersuchungen.
Self-report inventories are susceptible to response distortion. This study estimates the sensitivity and specificity of the German version of the Personality Assessment Inventory (PAI) in the detection of negative response distortion. The results of two samples are reported: (a) 25 experimental malingerers completed the PAI, the Beck Depression Inventory II (BDI-II) and the Structured Inventory of Malingered Symptomatology (SIMS). (b) 95 subjects who underwent psychiatric and neurologic examination, completed the Word Memory Test (WMT), the SIMS, the PAI, and in 44 cases the BDI-II. The validity scales of the PAI detected 72 % of the experimental malingerers; the SIMS 92 %. In the examinees, 62 % of the subjects classified as probably malingering according to the criteria of Slick, Sherman & Iverson (1999) were detected. The validity scales of the PAI need further analyses in the German language area.
