目的:对简式中文版黑暗四联征量表(the Chinese version of the short dark tetrad scale,SD4-C)在大学生群体中进行修订.方法:初测2886人,使用探索性因素分析、项目分析及验证性因素分析对量表进行修订;一个月后抽取675人进行重测信度及效标关联效度检验.结果:SD4-C包括4个维度,每个维度3题,共12题.总量表Cron-bach's α 系数为0.66,四个维度的Cronbach's α系数分别为马基雅维利主义0.63,自恋0.63,精神病态0.56,施虐狂0.73,对应维度的重测信度分别为0.40,0.30,0.45,0.67.量表结构较好(CFI=0.93,TLI=0.90,RMSEA=0.06,SRMR=0.05),项目区分度为[0.97,3.55],对应维度的区分度均值分别为1.61,2.01,1.50和2.34.项目难度参数为[-4.56,4.37].结论:SD4-C满足心理测量学的规范,适宜在中国大学生群体中使用.
Revision of the Short Dark Tetrad Scale in Chinese University Students
Objective:To revise the Chinese version of the short dark tetrad scale(SD4-C)in a sample of university stu-dents.Methods:The initial assessment involved 2,886 participants,using exploratory factor analysis(EFA),item analysis,and confirmatory factor analysis(CFA)to revise the scale.A subset of 675 students was retested one month later to examine reliability and criterion validity.Results:SD4-C consisted of 4 dimensions,each containing 3 items,totaling 12 items.The Cronbach's α coefficient for the overall scale was 0.66,while the Cronbach's α for the four dimensions were as follows:Ma-chiavellianism 0.63,Narcissism 0.63,Psychopathy 0.56,and Sadism 0.73.The test-retest reliability for the corresponding dimensions was 0.40,0.30,0.45,and 0.67,respectively.The scale demonstrated a good structural fit(CFI=0.93,TLI=0.90,RMSEA=0.06,SRMR=0.05).The item discrimination ranged from 0.97 to 3.55,with mean discrimination values for the di-mensions being 1.61,2.01,1.50,and 2.34.The item difficulty parameters ranged from-4.56 to 4.37.Conclusion:The SD4-C meets psychometric criteria and is suitable for use among Chinese university students.
