This study determined the validity and reliability of a new, abbreviated version of the Spanish Barratt Impulsiveness Scale (BIS-15S) in Colombian subjects. METHOD: The BIS-15S was tested in non-clinical (n=283) and clinical (n=164) native Spanish-speakers. Intra-scale reliability was calculated using Cronbach's α, and test-retest reliability was measured with Pearson correlations. Psychometric properties were determined using standard statistics. A factor analysis was performed to determine BIS-15S factor structure. RESULTS: 447 subjects participated in the study. Clinical subjects were older and more educated compared to non-clinical subjects. Impulsivity scores were normally distributed in each group. BIS-15S total, motor, non-planning and attention scores were significantly lower in non-clinical vs. clinical subjects. Subjects with substance-related disorders had the highest BIS-15S total scores, followed by subjects with bipolar disorders and bulimia nervosa/binge eating. Internal consistency was 0.793 and test-retest reliability was 0.80. Factor analysis confirmed a three-factor structure (attention, motor, non-planning) accounting for 47.87% of the total variance in BIS-15S total scores. CONCLUSIONS: The BIS-15S is a valid and reliable self-report measure of impulsivity in this population. Further research is needed to determine additional components of impulsivity not investigated by this measure.
本研究确定了西班牙版巴拉特冲动性量表（BIS - 15S）的一个新的简化版本在哥伦比亚受试者中的有效性和可靠性。方法：对以西班牙语为母语的非临床受试者（n = 283）和临床受试者（n = 164）进行了BIS - 15S测试。使用克朗巴哈α系数计算量表内部信度，通过皮尔逊相关性测量重测信度。采用标准统计方法确定心理测量学特性。进行因子分析以确定BIS - 15S的因子结构。结果：447名受试者参与了研究。与非临床受试者相比，临床受试者年龄更大且受教育程度更高。冲动性得分在每组中均呈正态分布。非临床受试者的BIS - 15S总分、运动、非计划性和注意力得分显著低于临床受试者。患有物质相关障碍的受试者BIS - 15S总分最高，其次是双相情感障碍和神经性贪食症/暴饮暴食症受试者。内部一致性为0.793，重测信度为0.80。因子分析证实了一个三因子结构（注意力、运动、非计划性），占BIS - 15S总分总方差的47.87%。结论：BIS - 15S是该人群中一种有效且可靠的冲动性自我报告测量工具。需要进一步研究以确定该测量工具未调查的冲动性其他组成部分。
