摘　　要：目的:探讨心理生理检测方法在精神疾病司法鉴定中对伪装精神疾病的鉴别意义。方法:对在精神疾病司法鉴定中收集的明确诊断的29例符合中国精神障碍分类和诊断标准(Chinese Classification andDiagnostic Criteria for Mental Disorders,the3rd editionCCMD-3)的精神障碍者及16例拟诊诈病者实施心理生理检测。使用PG-10型多道生理测量仪,以准绳问题测试法进行测试。比较两组在关于是否意图诈病问题上的说谎反应率,探讨该检测方法对诈病的鉴别价值。采用t检验及卡方检验进行资料统计分析。结果:诈病组在关于是否意图诈病的两个测题上说谎反应率分别为93.7%(15/16)和56.2%(9/16),而患者组均为0(0/29),差异有统计学意义(P<0.05)。以心理生理检测鉴别诈病的灵敏度为93.7%,特异度100%。结论:心理生理检测鉴别诈病灵敏度及特异性较高,但本研究样本量偏小,需扩大样本进一步研究。Objective： To explore the value of polygraph test for identifying malingered mental disorders in psychiatric testimony. Methods： According to the Chinese Classification and Diagnostic Criteria for Mental Disorders, the 3rd edition （ CCMD-3） , 29 patients with definite mental disorders and 16 cases who were considered as malingering received polygraph test. All subjects were assessed with the control question test by polygraph （ Type PG-10） . The value of polygraph for identifying malingered mental disorders was evaluated by comparing the difference in lying rates between the two groups. The t-test and Chi-square test were used to analyze these data. Results： The lying rates of the two target questions in malingering group were 93.7% （ 15/16 ） and 56. 2% （ 9/16 ） respectively, that in the mental disorders group was 0 （ 0/29 ） . The differences between the two groups were significant. The sensitivity and specificity of the test were 93.7% and 100% respectively. Conclusion： There were great sensitivity and specificity to differentiate malingering in psychiatric testimony by polygraph. But it is necessary to collect more subjects to test in the future.
