精神疾病中的凶杀行为与责任能力评定

Homicide and assessment of responsibility In psyohosis

目的 探讨精神疾病与凶杀行为的关系及责任能力评定的现状。方法 采用回顾性研究方法，对既往鉴定中精神疾病凶杀案例进行分析研究。结果 精神分裂症和偏执性精神病患者凶杀行为的发生率显著高于其他危害行为（Ｐ均小于０．０１），而精神发育迟滞、人格障碍及性变态出现凶杀行为，显著低于其他危害行为（Ｐ均小于０．０１）。对精神疾病患者凶杀行为责任能力评定绝大多数为无责任能力，少数为限定责任能力，极少为有责任能力。结论 精神病人各类危害社会行为中以凶杀的发生率最高，危害性极大，应加强防范。尽管现时对精神病人危害行为任责任能力的评定趋严，但其凶杀行为的责任能力仍以无责任能力为主。

Objective To explore the relationship between the psychosis and homicide, and the assessment of homicide re- sponsibility. Methods The retrospective method of analysis applied to the cases of homicide in psychosis from forensic assess- ments carried out in department of forensic psychiatry, nanjing brain hospital. Results The homicide behavior was significantly higher than the other illegal behaviors in schizophrenia and paranoid psychosis( all P <0.01) and was significantly lower than the other illegal behaviors in mental retardation, personality disorder and sexual deviation(all P <0.01). The responsibility of homi- cide was mainly the absence of ability in psychosis. Conclusions The homicide behavior frequently appears in various illegal behaviors in psychosis and may be more dangerous, so we should prevent it. Although the trend of assessment of responsibility has become more stringent, there is usually no responsibility for homicide in psychosis.
