title: Characteristics of homicide offenders with Schizophrenia from the Russian Federation.
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
