Dangerous Offences by Psychotics- A Study of Causative Factors and Prevention of the Offences -

在司法档案资料的基础上，对320例精神分裂症罪犯的犯罪史进行了调查，并试图分析其犯罪的成因，探讨其预防措施。这些罪犯在1980年期间被法官或检察官允许以精神错乱为由进行辩护，包括119起谋杀、74起纵火、12起抢劫、19起性犯罪和96起人身伤害案件。在大多数情况下，患者在犯罪时无法接受任何精神治疗，与家人住在一起。问题是病人对家属缺乏了解，拒绝治疗。在抢劫、人身伤害和谋杀的罪犯中，可以看到一群独居并倾向于重复危险犯罪的病人。大约10%的患者有四次以上的犯罪记录。根据犯罪史的不同，可将其分为“人格诱发型”和“精神诱发型”两类。4 .一些在精神病院反复发生暴力犯罪的病人与普通病人同病房治疗的风险引起我们的注意。在大多数情况下，病人没有受到起诉并被送进精神病院，但他们中的许多人在相当短的时间后就离开了医院。5 .在这个国家，有时作出医疗决定时完全不考虑再犯的危险。影响精神分裂症患者重复犯罪的重要因素有：a.多次前科；b.治疗困难；c.Antisocial人格;d.Bad environment.7。为了更好地规划医疗模式，我们提出了一种基于三级行政结构的医疗模式。但对于屡次犯罪的案件，我们认为有必要采取安全措施。

On the basis of the judicial files, we investigated the criminal history of the 320 cases of schizophrenic offenders, and made an attempt to analyze the causative factors of the offences and examine prevention of them. These offenders were allowed the defense of insanity by the judge or the prosecuter during 1980, and were consisted of 119 cases of murder,74 of arson, 12 of robbery, 19 of sex offences and 96 of bodily injuries.1. In most cases, patients could not receive any psychiatric treatment at the time of offences, living with their families. The problem is lack of understanding of their families and refusal of treatment by the patients.2. A group of patients who live alone and tend to repeat dangerous crimes can be seen among the offenders who committed robbery, bodily injuries and murders.3. About ten percent of patients have more than four criminal records. According to difference of criminal history, they may be classified into two groups, namely, "personality-induced type" and "psychosis-induced type"4. Some patients who repeated violent offences in mental hospitals arouse our attention to the risk of treating them together with general patients in the same ward.5. In Most cases, patients were not prosecuted and admitted to mental hospitals, but many of them left the hospital after rather short time. Medical decisions are given sometimes with no regard to the risk of recidivism, in this country.6. The important factors affecting repetition of crimes by schizophrenics are: a.Many times of previous arrest; b.Difficulty of treatment; c.Antisocial personality; d.Bad environment.7. As a better plan of medical model, we presented one based on the three classes of administrative structure. But for the cases of repeated offences, we feel the need of security measures.
