目的为界定小学生冲动行为,采用Barratt冲动量表(BIS)对BIS进行信度效度检验。方法采用系统抽样方法选取1 200名7~12岁小学生,由其父母完成BIS-11中文版的测试,使用修订后的BIS-11中文版量表进行探索性因素分析与验证性因素分析,并且用Cronbach′sα系数、分半信度系数和重测信度系数进行信度检验。采用SPSS 11.0软件进行统计学分析。结果 1.BIS-11包括3个因素:注意力冲动性、运动冲动性和无计划冲动性。采用Lickter4点量表计分,由1分(从不/很少)到4分(几乎总是/总是),总分为24~96分。2.BIS-11的Cronbach′sα系数为0.86,分半信度系数为0.82,重测信度系数为0.91。量表包括的3个因素解释了总方差的41.724%,验证性因素分析显示量表的结构效度较好,近似误差均方根=0.049。结论 BIS-11中文版具有较好的信效度,是一种较好的对小学生冲动行为测评的工具。
Objective To define the impulsive behavior of pupils and to test the reliability and validity of BIS using the Barratt Impulse Scale (BIS). Methods A total of 1,200 primary school students aged 7-12 years were selected by systematic sampling method. The Chinese version of BIS-11 was tested by their parents. The revised BIS-11 Chinese version was used for exploratory factor analysis and confirmatory factor analysis. Cronbach’s α coefficient, half-reliability coefficient and test-retest reliability coefficient were used to test the reliability. Using SPSS 11.0 software for statistical analysis. Results 1.BIS-11 includes three factors: attention-impulsive, athletic and unplanned impulsive. Points were scored on a Lickter 4-point scale from 1 point (never / rarely) to 4 points (almost always / always) with a total score of 24-96. 2.BIS-11 Cronbach’sα coefficient of 0.86, half-reliability coefficient of 0.82, test-retest reliability coefficient of 0.91. Three factors included in the scale explained 41.724% of the total variance. Confirmatory factor analysis showed that the scale validity of the scale was good. The rms of the approximate error was 0.049. Conclusion The Chinese version of BIS-11 has good reliability and validity, which is a good tool to evaluate the impulsive behavior of pupils.
