本研究确定了新版西班牙语Barratt冲动量表（BIS-15S）在哥伦比亚被试中的效度和信度。BIS-15S在非临床（n=283）和临床（n=164）西班牙语母语者中进行了测试。量表内信度采用Cronbach 's α计算，重测信度采用Pearson相关测量。使用标准统计确定心理测量特性。采用因子分析确定BIS-15S因子结构。447名受试者参与了这项研究。与非临床受试者相比，临床受试者年龄更大，受教育程度更高。冲动得分在各组中呈正态分布。与临床受试者相比，非临床受试者的BIS-15S总分、运动、非计划和注意得分显著低于临床受试者。物质相关障碍患者的BIS-15S总分最高，其次是双相情感障碍和神经性贪食/暴食症患者。内部一致性为0.793，重测信度为0.80。因子分析证实三因素结构（注意、运动、非计划性）占BIS-15S总分总方差的47.87%。BIS-15S是一个有效和可靠的自我报告测量冲动在这一人群。需要进一步的研究来确定冲动性的其他成分，而不是通过这个测量来调查的。
This study determined the validity and reliability of a new, abbreviated version of the Spanish Barratt Impulsiveness Scale (BIS-15S) in Colombian subjects. 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. 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. 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.
