摘　　要：目的：了解精神分裂症患者与正常人的罗夏测验自我损伤指数（EII）差异。方法：选取符合美国精神障碍诊断与统计手册第4版（DSM-IV）精神分裂症诊断标准的患者60例（年龄17~53岁）及性别、年龄与之匹配的正常对照组60例,分别对两组被试实施罗夏测验。对被试罗夏测验的反应进行编码与记分,计算出两组被试的EII值,比较两组被试EII及其各分变量（歪曲形状质量、认知加工错误加权和、歪曲感知人类运动、批判性内容、好的人物表征和坏的人物表征）的差异,分析EII对此两组被试的区分程度。结果：精神分裂症组的EII[（0.7±1.7）vs.（-0.9±0.9）]、歪曲形状质量[（6.2±2.3）vs.（3.4±2.6）]、认知加工错误加权和[（14.0±6.5）vs.（7.2±4.2）]、歪曲感知人类运动[（0.7±1.2）vs.（0.3±0.7）]、坏的人物表征[（3.1±2.7）vs.（1.8±1.8）]得分高于正常对照组（均P〈0.05）,但两组＂好的人物表征＂和＂批判性内容＂得分差异均无统计学意义（均P〉0.05）。诊断试验结果显示当EII值为-0.5时,对精神分裂症和正常人区分的灵敏度为0.91,特异度为0.75,Youden指数为0.66。结论：与正常人相比,精神分裂症患者的自我功能存在较严重的损伤,罗夏测验自我损伤指数区分精神分裂症患者的敏感性较高,但特异性较低,尚须进一步完善。Objective： To investigate the differences of Ego Impairment Index （EII） of Rorschach test be- tween patients with schizophrenia and normal individuals. Methods： Totally 60 patients with schizophrenia （ 17 - 53 years old） meeting the criteria of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition （DSM-IV） and 60 age-and gender-matched normal Subjects were involved in this study. The Rorschach ink blots test was used in both patients and normal subjects. The Ego Impairment Index （EII） of all the participants were calculated on the basis of their responses to the Rorschach ink blots test. The Eli and the subcomponents of it （including distorted form quality, weighted sum of cognitive processing errors, distorted perceptions of human movement, critical content, good human representation, and poor human representation）of the two samples were compared to explore Eli＇s discrimination to patients and normal individuals. Results： The score of EII[（0.7 ± 1.7） vs. （ - 0.9 ± 0.9）],distorted form quality [（6.2 ± 2.3） vs. （3.4 ± 2.6）], weighted sum of cognitive processing errors [（14.0 ± 6. 5） vs. （7.2± 4. 2）], distorted perceptions of human movement [（0. 7 ± 1.2） vs. （0. 3 ± 0. 7）], and poor human representation [ （3.1 ± 2. 7） vs. （ 1.8 ± 1.8） ] were higher in patients than in normal participants （Ps 〈 0. 05）. No significant differences were found for the score of good human representation and critical content between the two groups （Ps 〉 0. 05）. The result of Diagnostic Test showed that when EII equaling to - 0. 5, the sensitivity, specificity, and Youden Index of it to distinguish patients from normal individuals were 0. 91,0. 75, and 0. 66 respectively. Conclusion： It suggests that the ego functions of patients with schizophrenia have become serious damage compared with normal individuals. The EII of Rorschach test has high sensitivity while relatively low speci- ficity in discriminating patients with schizophrenia
