The Barratt Impulsiveness Scale-11 (BIS-11) is an important tool for measuring impulsivity in suicide research. This study aimed to assess psychometric characteristics of Chinese version of BIS-11 in suicides and controls of rural China. Data of 200 pairs of suicide cases and living controls were collected by psychological autopsy method. The Cronbach's alpha coefficients of BIS-11 were 0.936 for suicides, and 0.892 for living controls. Convergent validity analysis demonstrated a significantly positive correlation between the scores of BIS-11 with the scores of Beck Hopelessness Scale and Trait Anxiety Inventory. Confirmatory factor analyses indicated that the BIS-11 structure was basically suitable in rural China. With its high reliability, few items in BIS-11 may need a modification in order to further improve the construct validity of this instrument for suicide research in rural China.
Barratt 冲动量表-11（BIS-11）是自杀研究中测量冲动的重要工具。本研究旨在评估中文版 BIS-11 在农村自杀者和对照组中的心理测量学特征。采用心理解剖法收集了 200 对自杀病例和存活对照的资料。BIS-11 对自杀者的克朗巴赫α系数为 0.936，对存活对照的克朗巴赫α系数为 0.892。收敛效度分析表明，BIS-11 得分与 Beck 绝望量表和特质焦虑量表得分呈显著正相关。验证性因子分析表明，BIS-11 的结构在中国农村基本适用。BIS-11 具有较高的信度，为了进一步提高该工具在中国农村自杀研究中的结构效度，可能需要对其进行修改。
