The Chinese Version of the Barratt Impulsiveness Scale 11th Version (BIS-11) in College Students:Its Reliability and Validity

Objective: The purpose of the present study was to examine the psychometric properties of the Chinese translation of the Barratt Impulsiveness Scale 11th version (BIS-11-C) in a sample of Chinese university subjects. Methods: 209 undergraduate students from Hunan University completed the BIS-11-C and self-report questionnaires assessing risky behaviors. In order to assess test-retest reliability, the BIS-11-C was re-administered to participants one month later. Results:Item analysis showed that BIS-11-C had satisfactory item discrimination; The internal consistency of the BIS-11-C Cronbach's alpha =0.80 and the test-retest reliability was 0.83; Confirmatory factor analysis identified six correlated first-order factors which converged into three second-order factors: attention, motor and non-planning impulsiveness factors, which could explained 52.64% of total variance. Further, the BIS-11-C was significantly correlated with a wide variety of problem behaviors of Risk Behavior Questionnaire.Conclusion:The results of the current study indicate that the Chinese version of the BIS-11 is a currently useful tool in assessing impulsiveness.
