Abstract
Zusammenfassung. Die vorliegende Studie untersucht die Konstruktvalidität und Faktorenstruktur der deutschen Version des Youth Psychopathic Traits Inventory (YPI), einem Selbstbeurteilungsverfahren, welches psychopathische Persönlichkeitseigenschaften effizient erfasst. Die Verteilung psychopathischer Persönlichkeitseigenschaften und deren Korrelation mit der selbstberichteten Delinquenz wird in einer repräsentativen Schulstichprobe (N = 840) untersucht. Das YPI zeigte in der deutschsprachigen Version eine gute interne Konsistenz (α = .92). Die Jungen erreichten signifikant höhere Werte als die Mädchen. Die drei Faktoren (interpersonaler, affektiver und behavioraler Faktor) der Originalversion wurden sowohl für Jungen als auch für Mädchen bestätigt. Außerdem korrelierten alle drei Faktoren mit der selbstberichteten Delinquenz. Mit der deutschsprachigen Version des YPI sind psychopathische Persönlichkeitseigenschaften im Selbsturteil reliabel und valide erfassbar.
Abstract. The present study examined the construct validity and factor structure of the German version of the Youth Psychopathic Traits Inventory (YPI), a self-report measure assessing psychopathic personality traits efficiently. The distribution of psychopathic traits and their correlation with self-reported delinquency were examined in a representative school sample (N = 840). The German version of the questionnaire showed a good internal consistency (α = .92). Boys had significantly higher scores than girls did. Moreover, all three factors of the original version were confirmed for boys and girls. All three factors correlated with self-reported delinquency. Thus, the German version of the YPI is a reliable and valid measure of self-reported psychopathic traits.
