Sample
659 adolescents (ages 10- 20 years of age) recruited from schools (n = 521) and online participation (n = 138)..

Translation Method
The Italian language version of the BIS-11 (Fossati, Di Ceglie, Acquarini, and Barratt, 2001) was translated to German by Dr. Andrea Hartmann and a second confirmatory translation was performed by a licensed translator for comparison purposes.

Item Analysis
Cronbach’s alpha = .74
Test-retest reliability (6-month; n = 98)  r = .66

Factor Analysis 
Exploratory factor analysis (unweighted least squares with Promax rotation) identified a 3 factor model. Item loading were slightly different than the English language loading identified by (Patton, Stanford, & Barratt, 1995).

Convergent Validity 
Validity demonstrated by correlation with the Inventory for the Assessment of Impulsiveness, Venturesomeness, and Empathy (IVE); German BIS-11 Total score significantly correlated with IVE Impulsivity (r = .51).
