Impulsivity is associated with different psychiatric disorders. The Barratt Impulsiveness Scale version 11 is one of the scales mostly used to measure impulsivity and it does not have a validated version for Brazilian Portuguese. The objective of this study is to adapt and conduct the construct validation of the Barratt Impulsiveness Scale version 11 for adolescents.
The scale was translated and adapted into Portuguese and then back-translated into English. The psychometric proprieties, factor analysis and construct validity were evaluated in two samples: 18 bilingual undergraduate medical students and 464 male adolescents between 15 and 20 years old from a well-delimited geographical area in the city of Canoas, southern Brazil.
The adolescent sample had a mean age of 17.3 +/- 1.7 years. Intra-class correlation coefficient achieved a value of 0.90, and internal consistency had a of 0.62. Factor analysis did not identify the 3 factors of the original scale. Impulsivity scores from the Barratt Impulsiveness Scale version 11 had a correlation with scores for attention deficit/hyperactive disorder and oppositional defiant disorder and with number of symptoms of conduct disorder, suggesting an appropriate construct validity of the scale.
Even considering some limitations in the Portuguese version, Barratt Impulsiveness Scale version 11 can be used in male adolescents and should be tested in other populations.
冲动性与多种精神疾病相关。巴雷特冲动性量表第11版是最常用于测量冲动性的量表之一，且尚无巴西葡萄牙语的有效版本。本研究的目的是对巴雷特冲动性量表第11版进行改编并对青少年进行结构效度验证。
该量表被翻译成葡萄牙语并进行改编，然后再回译成英语。在两个样本中评估了心理测量学特性、因子分析和结构效度：18名双语本科医学生以及来自巴西南部卡诺阿斯市一个界定明确地理区域的464名15至20岁的男性青少年。
青少年样本的平均年龄为17.3±1.7岁。组内相关系数达到0.90，内部一致性为0.62。因子分析未识别出原始量表的3个因子。巴雷特冲动性量表第11版的冲动性得分与注意力缺陷/多动障碍和对立违抗障碍的得分以及品行障碍的症状数量相关，表明该量表具有适当的结构效度。
尽管葡萄牙语版本存在一些局限性，但巴雷特冲动性量表第11版可用于男性青少年，且应在其他人群中进行测试。
