Psychometrische Evaluation der deutschen Barratt Impulsiveness Scale - Kurzversion (BIS-15) - Psychometric evaluation of the German Barratt Impulsiveness Scale - Short Version (BIS-15).

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.
