Abstract ObjectiveThe aim of the study was to examine the psychometric properties of the Chinese revised version of Barratt Impulsiveness Scale 11th (BIS-11) in Chinese college student with a web-based survey. MethodsA total of 2 295 college students were enrolled in the survey,and were divided into two groups.The first group was used for item and factor analysis, and the second group was used for confirmatory factors analysis. ResultsItem analysis indicated that BIS-11 had satisfactory item discrimination, except the item 29. Three-factor model of BIS-11 was well documented with exploratory factor analysis (explained 45.526% of total variance) and confirmatory factor analysis (GFI, AGFI, TLI, CFI, RMSEA was 0.872, 0.851, 0.853, 0.864, 0.064, respectively). The internal consistency of the total scale and the three subscales using coefficient alpha was in the range of 0.833-0.913. The split-half reliability of the total scale and the three subscales using Spearman-Brown Coefficient was in the range of 0.827-0.907. Furthermore, the female college students in the present study had higher scores on the total scale, cognitive (attention) impulsiveness factor, and motor impulsiveness factor than the male college student (P<0.01). The individuals with GHQ-12 (the twelve-item General Health Questionnaire) screen-positive had higher scores on the total scale and the three factors than the subjects with GHQ-12 screen-negative (P<0.01). ConclusionThe results of present study suggested that the Chinese revised version of the Barratt Impulsiveness Scale 11th could be used as a tool of impulsiveness assessment in web-based survey.
