It has been suggested that the characteristics of homicides committed by people with schizophrenia from regions with a high total homicide rate differ from the characteristics of homicides by people with schizophrenia from regions with low rates of homicide.
Homicide offenders in the Chuvash Republic of the Russian Federation have been systematically examined for over 30 years. This study reports on a review of the documents from pre-trial psychiatric assessments and legal proceedings of all people charged with homicide offenses between 1981 and 2010 who were found to have schizophrenia.
There were 133 people (120 men, 13 women) with an ICD-10 diagnosis of schizophrenia who committed a homicide offense in the 30 years of the study, including 15 repeat homicide offenders and 9 homicides with multiple victims. The odds ratio (OR) for homicide associated with schizophrenia was 13.5, 95% confidence interval (CI) (11.4-16.0). The mean age of the offenders was 34.8 (SD 9.6) and most had the paranoid subtype of schizophrenia (78%). The majority of victims were family members (51%) or acquaintances (43%). Delusions of persecution, auditory hallucinations and other positive symptoms were present in 58% of offenders at the time of the homicide. The remaining 42% exhibited negative symptoms such as emotional deficits, had antisocial attitudes or were regarded as having impaired self-control. Alcohol intoxication was reported at the time of 45% of homicides. Stabbing was the most common method and few of the homicides involved firearms.
The characteristics of homicide offenders with schizophrenia from Chuvashia do not appear to differ greatly from those of homicide offenders with schizophrenia from regions with far lower rates of homicide.
有人提出，高总体杀人率地区的精神分裂症患者杀人的特征与低杀人率地区的精神分裂症患者杀人的特征不同。
俄罗斯联邦楚瓦什共和国对杀人罪犯进行了长达 30 多年的系统检查。本研究报告了对 1981 年至 2010 年期间所有被指控犯有杀人罪且被发现患有精神分裂症的人的预审精神病评估和法律诉讼文件的审查，这些人中有 133 人（120 名男性，13 名女性）。
在研究的 30 年中，有 133 人（120 名男性，13 名女性）患有 ICD-10 诊断的精神分裂症，其中有 15 人是重复杀人罪犯，有 9 人是多人受害者。与精神分裂症相关的杀人的优势比（OR）为 13.5，95%置信区间（CI）（11.4-16.0）。罪犯的平均年龄为 34.8（SD 9.6），大多数人患有偏执型精神分裂症（78%）。大多数受害者是家庭成员（51%）或熟人（43%）。在杀人时，58%的罪犯存在妄想、幻听和其他阳性症状。其余 42%的罪犯表现出情感缺陷、反社会态度或被认为自我控制能力受损等阴性症状。有 45%的杀人事件报告了酒精中毒。刺戳是最常见的方法，很少有杀人事件涉及枪支。
楚瓦什的精神分裂症杀人罪犯的特征似乎与那些来自杀人率低得多的地区的精神分裂症杀人罪犯的特征没有太大区别。
