司法鉴定评定中抑郁症P_(300)电位及人格测定的研究

A study on P_(300) potentials and personality of responsible appreciation with depression by judicial expertise

目的:探讨P300电位及人格测定在抑郁症司法鉴定评定中的价值。方法:对61名经司法鉴定为无或限定责任能力的抑郁症患者及30名正常者进行了P300电位、艾森克个性问卷(EPQ)测定,并将结果加以比较及回顾性分析。结果:无责任能力组及限定责任能力组的抑郁症患者P300电位中N2、P3潜伏期和P3波幅较正常组明显延长(P<0.01或P<0.05),其中无责任能力抑郁症患者组P300电何成分中N2及P3滞伏期较限定责任能力组延长,P3波幅降低,存在显著性差异(P<0.05)。无责任能力组及限定责任能力组EPQ特质中N量表分明显高于正常组(P<0.01或P<0.05),E、L分低于正常组(P<0.05)。结论:P300电位及人格测定在抑郁症司法鉴定评定中有较高的参考价值。

Objective： To explore the value of P300 potentials and EPQ with responsible appreciation in depression by judicial expertise. Methods：P300 potentials and EPQ test were used for 61 no or limited responsible depression patients by judicial expertise and 30 normal healthy peoples. The results were retrospective compared and analyzed. Results： Latent period of N2 and P3 of P300 potentials and the amplitude of P3 with no or limited responsible depression patients were significant longer and lower than the normal group （ P 〈0.01 or P 〈0.05 ）, Latent period of N2 and P3 of P300 potentials and the amplitude of P3 with the no responsible depression group were significant longer and lower than limited responsible depression group （ P 〈 0.05 ）. The factor scale of E and L of EPQ with no or limited responsible depression were significant higher than normal group （P 〈 0.01 or P 〈 0.05 ）, and the factor scale of N of EPQ with no or limited responsible depression group was significant higher than the normal group （ P 〈 0.05 ）. Conclusions： P300 potenrials test and EP0 have remarkable value with responsible appreciation in depression by judicial expertise.
