摘要
目的：建立事件影响量表-修订版22个条目量表（IES-R）的中文版。方法：439名经过至少1件创伤性事件的女犯人完成了IES-R，分析量表的重测信度和内部一致性、条目间平均相关系数；总分与各因子间的相关系数、内容区分效度，并进行划界分的诊断性评价。结果：IES—R中文版的重测信度为0．86，Cronbach＇sα系数为0．96，条目间平均相关系数在0．42—0．60之间。总分与各因子的相关系数在0．84—0．91之间，各因子间的相关系数在0．75～0．89之间，PTSD组的总分明显高于非PTSD组。划界分35时，对PTSD和部分PTSD诊断预测的敏感度为0．86、特异度0．86、诊断效率0．85。结论：IES-R中文版具有良好的信、效度，在我国可以作为一种较好的创伤后应激症状的测评工具。划界分35，量表对PTSD和部分PTSD有一定的预测力。
Objective： To develop the Chinese version of the 22-item Impact of Event Scale-Revised （IES-RC） and examine its reliability and validity. Methods： A sample of 439 female offenders experiencing at least one traumatic life event was tested. The authors examined the IES-R-C＇s retest reliability, internal consistency, discriminative validity and predictive value of the cut-off. Results： The test-retest reliability coefficient was 0. 86 ; The Cronbach＇s coefficient of the IES-R-C was 0. 96 ; The mean inter-item correlation coefficients ranged from0.42 to 0. 60 ; The correlation coefficient of the three factors with the total scale scores ranged from0.84 to 0. 91 ; The correlation coefficient among the three factors ranged from 0. 75 to 0. 89 ; Posttraumatic stress disorder （PTSD） and partial PTSD cases indicated significantly higher scores than non-PTSD cases. 34/35 in the IES-R-C total score seemed an appropriate cutoff indicative of high levels of sensitivity （ 0. 86 ） , specificity （ 0. 86 ）, and efficiency （ 0. 86 ） in the broadly defined PTSD-positive groups （ PTSD ＋ partial PTSD） . Conclusion： the of IES-R-C is a reliable and valid measure for assessing the posttranmatic stress symptoms in Chinese-speaking sample. The IES-R-C may be a useful self-rating diagnostic instrument particularly for survivors with PTSD symptoms as a clinical concern （ PTSD ＋ partial PTSD） by using a 34/35 cutoff in total score.
