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. 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. 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. 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.

土耳其和俄罗斯患有精神病的杀人犯不承担刑事责任：国际比较

主要目标是对土耳其和俄罗斯的杀人案件及其患有精神疾病的凶手进行比较分析，以阐明背景的相似性和差异，并为加强该领域的国际研究提供新的视角。这项跨国回顾性研究在伊斯坦布尔、土耳其和俄罗斯楚瓦什共和国的法医精神病中心进行，研究对象是患有精神疾病 (ICD-10 F20-F29) 的个体，这些个体在 2012 年 12 月至2022 年 12 月。样本包括 92 名土耳其患者和 29 名俄罗斯患者，对他们的背景、临床特征和每次杀人行为进行了比较。二元分析显示，俄罗斯受试者受教育程度更高，一生中有更多自杀企图，患病时间更长，更频繁地认识熟人，遭受创伤性钝器杀人的比率更高，酒精或物质中毒的比率更高，并且在发生幻觉时出现妄想的比率较低。与土耳其同行相比，指数凶杀案发生的时间。多变量分析表明，受教育年限较长、终生自杀未遂频率较高、中毒发生率较高以及杀人时妄想发生率较低与属于俄罗斯群体有关。尽管存在一些相似之处，但两个样本之间的显着差异凸显了国际研究对于增强我们对社会文化背景下的心理健康、杀人犯罪和犯罪特征的理解的重要性。
