Intimate partner homicide (IPH) is a tragic event. Studies involving the comparison between IPH and intimate partner homicide-suicide (IPH-S) are scarce, with few studies in Portugal about this issue. The current study aims to compare IPH and IPH-S perpetrators, the victim-perpetrator relationships dynamics, and homicide circumstances. The data was collected through the analysis of 78 judicial processes of IPH that occurred in Portugal, between 2010 and 2015. Of the cases, 51 were IPH, 20 were IPH-S cases, and seven were attempted suicide cases, being perpetrated in 84.6% ( = 66) for male perpetrators. Suicide after intimate homicide were all committed by men. All judicial processes analyzed refer to heterosexual relationships. Bivariate and multivariate analyses were performed to compare the groups concerning perpetrator and victim sociodemographic characteristics, victim-perpetrator dyadic dynamics, and crime circumstances. The results show mostly common trends between the two groups with some differentiating factors when compared individually (e.g., perpetrator professional status, criminal records). Regression logistic analysis showed no differences between IPH and IPH-S.
亲密伴侣杀人（IPH）是一个悲剧性事件。涉及 IPH 和亲密伴侣杀人自杀（IPH-S）比较的研究很少，葡萄牙对此问题的研究也很少。本研究旨在比较 IPH 和 IPH-S 犯罪者、受害者-犯罪者关系动态以及杀人情况。数据是通过分析 2010 年至 2015 年期间在葡萄牙发生的 78 起 IPH 司法案件收集的。在这些案件中，51 起是 IPH，20 起是 IPH-S 案件，7 起是自杀未遂案件，84.6%（=66）是男性犯罪者所为。亲密杀人后的自杀行为均由男性实施。所有分析的司法程序均涉及异性恋关系。进行了双变量和多变量分析，以比较两组犯罪者和受害者的社会人口统计学特征、受害者-犯罪者二元关系动态以及犯罪情况。结果表明，这两个群体存在一些共同趋势，但个别比较时存在一些区别因素（例如，犯罪者的职业地位、犯罪记录）。回归逻辑分析显示 IPH 和 IPH-S 之间没有差异。
