目的 探讨司法鉴定中精神发育迟滞 (MR)患者辨认能力的影响因素。方法 对 86例MR司法鉴定资料进行判别分析 ,选出影响辨认能力的判别因子 ,并建立判别方程 ,进行组内回代检验。结果 经判别分析 ,有 5个因素被选入 :个性特征、诊断分组、是否伴有癫痫及其他精神病性症状、作案类型、作案动机 ,组内回代检验不同程度辨认能力的判断正确率分别为 :有完全辨认能力 93 8%、有部分辨认能力73 4 %、无辨认能力 1 0 0 %,总判断正确率为 89 0 %。结论 MR患者作案时辨认能力受多种因素的影响 ,否认了“单纯以诊断分级判断辨认能力”的观点。
Objective To explore the influential factors of identification ability of mental retardation (MR) in forensic identification. Methods The discriminant analysis of 86 cases of MR forensic identification data was conducted, and the discriminant factors that affected the ability to identify were selected and discriminant equations were established for the test of back-substitution in the group. Results According to the discriminant analysis, five factors were selected: personality characteristics, diagnosis grouping, epilepsy and other psychotic symptoms, the correctness of the type of crime, motivation of motivation, and the ability to identify different degrees of back-testing in the group were : There is a total recognition ability of 93 8%, partial identification ability of 73 4%, no identification ability of 100%, the total judgment correct rate of 89 0%. Conclusion The ability of MR patients to identify at the time of committing a crime is influenced by many factors and the concept of “ability to recognize a mere diagnosis based on diagnosis and classification” is rejected.
