To assess the psychometric properties of the Italian translation of the Barratt Impulsiveness Scale‐11 (BIS‐11), the scale was administered to 763 college undergraduates. Based on analyses using item‐total correlations and t‐tests for differences between the top and the bottom total score quartiles, all items from the English version of the BIS‐11 were retained in the Italian version. Cronbach's α for internal consistency was .79 and two‐month test–retest reliability was .89. An exploratory principal‐components analysis replicated the six first‐order factors and three oblique second‐order factors, consistent with the number identified in the English version. However, subfactor item loadings differed between the English and Italian versions. The overall item pool was consistent in being a homogeneous measure of impulsiveness. The BIS‐11 total score was correlated significantly with aggression and ADHD measures. The BIS‐11 also significantly differentiated between high and low levels of binge eating, alcohol consumption, and cigarette smoking. © 2001 John Wiley & Sons, Inc. J Clin Psychol 57: 815–828, 2001.
