精神病患者与精神正常者凶杀行为的对比研究

A comparative study of homicide behavior between psychotic patients and mentally normal subjects

为探讨精神病患者与精神正常者凶杀作案行为的异同点，对９２例精神病患者与８３例精神正常者的杀人行为进行了对比研究。结果：在作案时的年龄、大量杀人、杀害对象、作案场所、是否合伙作案、作案有无动机、作案前有无准备和作案后有无自杀行为等方面，精神病患者与精神正常者有显著性差异，此差异与发生精神病的年龄、疾病症状、病理变化等特点有关。结果还显示，如果作案者为女性、单独作案、凶杀对象是关系亲密的亲人，常常是由精神病患者所为。

In order to explore the feature of psychotic patient's homicide behavior, 92 psychotic patients and 83 mentally normal subjects were investigated in their homicide behavior. Significant difference was found in the criminal age, offender number, objects being killed, place, accomplices, homicide motive, preparation for offense and suicide after homicide between patients and mentally normal subjects. The difference was related to the age of psychosis onset, symptoms and pathological alternations of the patients. The result also showed that a homicider tended to suffer from mental disorders, if he/she was female, or killed his/her close relatives, or offended alone.
