摘要

Objective T o explore the characteristics of schizophrenia patients' hom icide behaviors and the influences of the assessm ents of crim inal capacity. Methods Indicators such as dem ographic and clinical data, characteristics of crim inal behaviors and crim inal capacity from the suspects w hom w ere diagnosed by forensic psychiatry as schizophrenia (n=110) and norm al m ental (n=70) w ith hom icide behavior, w ere collected by self-m ade investigation form and com pared. T he influences of the assessm ents of crim inal capacity on the suspects diagnosed as schizophrenia w ere also analyzed using logistic regression analysis. Results T here w ere no significant statistical differences betw een the schizophrenic group and the norm al m ental group concerning age, gender, education and m arital status (P>0.05). T here w ere significant sta-tistical differences betw een the tw o groups concerning thought disorder, em otion state and social function before crim e (P<0.05) and there w ere significant statistical differences in som e characteristics of the case such as aggressive history (P<0.05), cue, trigger, plan, crim inal incentives, object of crim e, circum stance cognition and self-protection ( P<0 .05 ) . M ultivariate logistic regression analysis suggested that thought disorder, em otion state, social function, crim inal incentives, plan and self-protection before crim e of the schizophrenic group w ere positively correlated w ith the crim inal capacity (P<0.05). Conclusion T he rele-vant influences of psychopathology and crim e characteristics should be considered com prehensively for im proving the accuracy of the crim inal capacity evaluation on the suspects diagnosed as schizophrenia w ith hom icide behavior.%目的 探讨精神分裂症者凶杀行为特征及影响刑事责任能力评定的因素.方法 自制调查表收集并比较经司法鉴定为具有凶杀行为的精神分裂症嫌疑人(n=110)与具有凶杀行为的无精神病者(n=70)的一般人口学资料、临床资料、作案行为特征、刑事责任能力等指标,并采用Logistic回归分析法探讨影响精神分裂症嫌疑人刑事责任能力的相关因素.结果 精神分裂症组和无精神病组在年龄、性别、文化程度、婚姻状态方面差异无统计学意义(P>0.05),两组在案发前思维障碍、情绪状态、社会功能等疾病相关因素方面差异均存在统计学意义(P<0.05),并在攻击行为史、作案先兆、诱因、预谋、作案动机、作案对象、环境辨认、自我保护等一些与案情有关的特点上存在差异(均P<0.05).多因素Logistic回归分析显示,精神分裂症组的刑事责任能力与案发前思维障碍、情绪状态、社会功能、动机、预谋、自我保护性等因素有关(P<0.05).结论 为提高对具有凶杀行为的精神分裂症嫌疑人刑事责任能力评定的准确性,应综合考虑相关精神病理因素及作案特征的影响.
