摘要
目的:检验临床用创伤后应激障碍(PTSD)诊断量表(CAPS)中文版的信效度。方法:在四川省什邡市某中学筛查出PTSD症状高分被试104例,由评估者进行CAPS结构式访谈;其中37例被试接受2位评估者的独立访谈,收集数据测算评分者信度。在某心理专科医院纳入ETI高分的被试35例进行CAPS访谈。在访谈结束3d后,再由评估者对被试进行人格障碍定式临床晤谈(SCID)问卷的PTSD模块访谈,收集数据测算校标效度。结果:2名评定者对37例被试的PTSD总体诊断的Kappa系数为1,CAPS总分及三项分量表得分的皮尔逊相关系数均>0.9,两者的评分显著相关(n=37,P<0.01),显示很强的评分者信度。CAPS量表总体的alpha系数>0.9,三项分量表的alpha系数均>0.75(n=139),显示CAPS中文版在总体水平和分量表水平上都具有可接受的同质性信度。CAPS与SCIDPTSD模块两个工具在总诊断上的Kappa值达到0.75(n=35),在总分及各项分量表得分上显著相关,说明作为测量PTSD的工具,CAPS具有良好的效标效度。结论:CAPS中文版是一项测量PTSD的可靠且有效的工具。
Objective：To examine the psychometric properties of Chinese version of Clinician Administered PTSD Scale （CAPS）. Methods： A total of 104 subjects with high score （〉16） on PTSD symptoms were screened in a high school in Shifang City, Sichuan Province. These subjects were interviewed by trained evaluators using CAPS. Thirty-seven subjects were rated by two evaluators independently for investigating inter-rater consistency. Another 35 subjects from a hospital for psychotherapy were interviewed using CAPS, and after 3 days of CAPS interviews, these subjects accepted the PTSD module of SCID interviews by trained evaluators for examining criterion-related validity of CAPS. Results： The coefficient of the overall PTSD diagnosis of 37 subjects rated by two raters was Kappoml. Pearson correlation coefficients of CAPS total score and three subscale scores were all above 0.9（n=37, P〈0.01）, showing strong inter-rater reliability. The alpha coefficient of CAPS total score was above 0.9, three sub- scale alpha coefficients were above 0.75（n=139）, showing that the Chinese version of CAPS had acceptable homogeneity in the overall level and subscale level. Kappa test of diagnostic data of CAPS and PTSD module of SCID showed that Kappa value reached 0.75 （n=35）, which meant in the total score and subscale scores these two mea- surements were significantly associated and CAPS had good criterion-related validity. Conclusion： Chinese version of CAPS was a reliable and effective tool of PTSD assessment.
