Abstract：
OBJECTIVE: The primary objective was to conduct a comparative analysis of homicide cases and their perpetrators with psychotic illnesses in samples from Turkiye and Russia to elucidate contextual similarities and differences, and providing novel perspectives to enhance international research in this field.
METHODS: This cross-national retrospective study, conducted at forensic psychiatric centers in Istanbul, Turkiye, and Chuvashia, Russia, involved individuals with psychotic illnesses (ICD-10 F20-F29) who were deemed criminally non-responsible for index homicide offenses between December 2012 and December 2022. The sample included 92 Turkish patients and 29 Russian patients who were compared for background, clinical characteristics, and each homicidal act.
RESULTS: Binary analyses revealed that Russian subjects were more educated, had more lifetime suicide attempts, longer illness duration, had acquaintances as victims more frequently, higher rates of blunt traumatic homicides, higher rates of intoxication with alcohol or substances, and lower rates of experiencing delusions at the time of the index homicide compared to their Turkish counterparts. Multivariate analyses indicated that more years of education, a greater frequency of lifetime suicide attempts, higher prevalence of intoxication and a lower rate of delusions at the time of the homicide were associated with belonging to the Russian group.
CONCLUSIONS: Despite several similarities, the remarkable differences between the two samples underscore the importance of international research in enhancing our understanding of mental health, homicidal offense and offender characteristics in the sociocultural context.

摘要：
目的：主要目的是对突厥基耶和俄罗斯的样本中的杀人案件及其精神病患者进行比较分析，以阐明上下文的异同，并提供新颖的视角来加强这一领域的国际研究。
方法：这项跨国回顾性研究，在伊斯坦布尔的法医精神病中心进行，Turkiye,还有Chuvashia,俄罗斯,涉及2012年12月至2022年12月期间被认为对索引杀人罪无刑事责任的精神病患者(ICD-10F20-F29)。样本包括92名土耳其患者和29名俄罗斯患者，他们进行了背景比较，临床特征,和每一个杀人行为。
结果：二元分析显示，俄罗斯受试者受教育程度更高，一生中有更多的自杀企图，病程较长,熟人更频繁地成为受害者，更高的钝性创伤性凶杀率，酒精或物质中毒的发生率更高，与土耳其同行相比，指数凶杀案发生时的妄想发生率较低。多变量分析表明，更多年的教育，一生中自杀企图的频率更高，在凶杀案发生时,较高的中毒发生率和较低的妄想发生率与属于俄罗斯人群有关.
结论：尽管有一些相似之处，两个样本之间的显着差异强调了国际研究在增强我们对心理健康的理解方面的重要性，社会文化背景下的杀人犯和罪犯特征。
