Psychometrische Evaluation der deutschen Barratt Impulsiveness Scale – Kurzversion (BIS-15)
Abstract
Zusammenfassung. Impulsivität ist ein Persönlichkeitsmerkmal, das mit schnellen, unüberlegten Handlungen ohne Beachtung möglicher negativer Konsequenzen einhergeht. Eines der am weitesten verbreiteten Verfahren zur Erfassung von Impulsivität ist die Barratt Impulsiveness Scale (BIS-11; Patton, Stanford & Barratt, 1995). Es wurde gezeigt, dass die drei Faktoren nicht-planende, motorische und aufmerksamkeitsbasierte Impulsivität auch ausreichend gut mit einer verkürzten Form der BIS-11 erfasst werden können (BIS-15; Spinella, 2007). Die vorliegende Arbeit stellt diese Kurzversion der BIS-11 in einer deutschen Übersetzung vor. Reliabilität und Faktorstruktur des Fragebogens wurden in einer Stichprobe (N = 752) von überwiegend Studierenden getestet. Die dreifaktorielle Struktur von Spinella (2007) konnte bestätigt werden. Die interne Konsistenz war gut (Cronbachs α = .81). In einer zweiten Studie (N = 51) zeigte sich konvergente Validität durch Zusammenhänge mit einem anderen Impulsivitätsmaß (UPPS). Die BIS-15 empfiehlt sich durch ihre guten psychometrischen Kennwerte und ihre ökonomische Durchführbarkeit für die Erfassung von Impulsivität im deutschen Sprachraum.
Abstract. Impulsivity is a personality trait which is characterized by rapid, unplanned actions regardless of possible negative consequences. One of the most widely used methods to assess impulsivity is the Barratt Impulsiveness Scale (BIS-11; Patton, Stanford & Barratt, 1995). The three factors nonplanning, motor, and attentional impulsivity can be measured sufficiently well with a short version of the BIS-11 (BIS-15; Spinella, 2007). The present study introduces the German version of this short version of the BIS-11. Reliability and factorial structure of this questionnaire were determined in a sample of predominantly university students (N = 752). The three-factorial solution was replicated. Internal consistency was good (Cronbach’s α = .81). Associations with another impulsivity questionnaire (UPPS) in a second study (N = 51) proved convergent validity. We recommend the BIS-15 for assessing impulsivity in German-speaking regions because of its good psychometric properties and economic procedure.
