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 alpha 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.
为评估巴雷特冲动性量表-11（BIS-11）意大利语翻译版的心理测量特性，该量表被施用于763名大学本科生。基于使用项目-总分相关性分析以及总分上下四分位数差异的t检验，BIS-11英文版的所有项目均保留在意大利语版中。内部一致性的克朗巴哈α系数为0.79，两个月的重测信度为0.89。探索性主成分分析重现了六个一阶因素和三个斜交二阶因素，与英文版中确定的数量一致。然而，英语版和意大利语版之间子因素的项目负荷有所不同。总体项目库在作为冲动性的同质测量方面是一致的。BIS-11总分与攻击性和注意力缺陷多动障碍测量显著相关。BIS-11在暴饮暴食、饮酒和吸烟的高水平与低水平之间也有显著差异。
