It is generally thought that schizophrenia does not predispose subjects to homicidal behavior. However, many previous studies have suffered from notable methodological weaknesses. In particular, obtaining comprehensive study groups of violent offenders has been difficult. Finnish police have been able to solve about 97 percent of homicides during the last few decades. Because most homicide offenders are subjected to intensive forensic psychiatric examination, we were able to obtain data for 93 homicide offenders with schizophrenia among 1,423 arrested during a 12-year period. Calculations of the odds ratios revealed that the risk of committing a homicide was about 10 times greater for schizophrenia patients of both genders than it was for the general population. Schizophrenia without alcoholism increased the odds ratio more than 7 times; schizophrenia with coexisting alcoholism more than 17 times males.
一般认为精神分裂症不会使个体倾向于实施杀人行为。然而，许多先前的研究存在显著的方法学缺陷。特别是，很难获得暴力犯罪者的全面研究群体。在过去几十年里，芬兰警方能够侦破约97%的杀人案件。由于大多数杀人犯罪者都接受了深入的法医精神病学检查，我们得以获取在12年期间被捕的1423人中93名患有精神分裂症的杀人犯罪者的数据。优势比的计算表明，精神分裂症患者无论男女实施杀人行为的风险比普通人群高出约10倍。无酒精中毒的精神分裂症使优势比增加超过7倍；同时存在酒精中毒的精神分裂症男性增加超过17倍。
