精神病患者刑事责任能力评定量表在司法精神病鉴定中的应用

The application of the rating scale of criminal responsibility for mentally disordered offenders in the forensic psychiatric expertise

目的:探讨精神病患者刑事责任能力评定量表(RSCRs)应用于司法精神病鉴定实践中的可能性。方法:对200例刑事责任能力鉴定案例进行RSCRS评分,对暴力犯罪案件增加暴力作案刑事责任能力评定量表(CRRSV)评定,并与专家鉴定意见进行比较。结果:全量表Cronbach'sα系数为0.944,Guttmann分半信度为0.890;除条目10、11,其余各条目之间及与总分相关性尚可(r>0.400,P=0.000);专家评定意见中不同等级责任能力及相互之间差异有统计学意义(F=548.038,P=0.000);探索性因素分析提取4个因子,累积贡献率为78.612%,验证性因素分析提示模型拟合度比较理想;RSCRs等级划分结果与专家鉴定意见一致性高(Kappa=0.876,P=0.000)。在暴力犯罪案件中,RSCRs和CRRSV总分高度正相关,等级一致性高(Kappa=0.873,P=0.000);判别函数回代92.5%的样本划分正确。结论:RSCRs具有较好的信效度,可用于司法精神病鉴定中作为刑事责任能力评定及分级的参考工具。

Objective： To explore the usage of the rating scale of criminal responsibility for mentally disordered offenders（ RSCRs） in the forensic psychiatric expertise. Method： 200 forensic psychiatry cases were assessed by RSCRs,and criminal responsibility rating scale of violence（ CRRSV） were assessed in violence cases. And the comparison was made between the scales and expert＇s opinion. Results： The total Cronbach＇s αwas 0. 944,Guttmann split-half reliability was 0. 890. All items have good correlation with each other and with the total score of the scale（ r 0. 400,P = 0. 000）,except 10 th and 11 th items. There were significant differences among the 3-level criminal responsibility（ F = 548. 038,P = 0. 000）. By the methodology of exploratory factor analysis four factors were extracted,which accounted for 78. 612%,and conformatory factor analysis result showed good fitness. The RSCRs cutoff scores have a high consistency with expert＇s opinion（ Kappa = 0. 876,P = 0. 000）. There was a significant positive correlation between the RSCRs and the CRRSV scores in violence cases,and have a high consistency（ Kappa = 0. 873,P = 0. 000）. The accuracy of retrospective cumulative square was 92. 5%. Conclusion： The RSCRs has good reliability and validity when applied,it can be used as a reference tool for criminal responsibility assessment and classification in the forensic psychiatric expertise.
