This study aims to identify, through an advanced three-level meta-analytic approach, the predictive validity of the different ecological systems for IPH perpetration and victimization relative to IPV, other homicides, IPH followed by suicide, and non-abused control groups. Twenty-nine studies were included, with 473 effect sizes in a unique population of 16,237. Each factor was classified into one of three ecological systems: ontogenetic, microsystem, and exosystem. The results revealed that the impact of each ecological system on the likelihood of IPH varies depending on the offender/victim gender and the comparison groups. Specifically, the largest odds ratios for intimate partner femicide (IPF) perpetration/victimization versus IPV were found at the microsystem level as well as IPF victimization versus non-abused group at the ontogenetic level of risk factors. Moderator analyses showed that the difference between male IPH and IPV perpetrators in the effect of the microsystem level of risk factors is explained in part by a set of cultural values and beliefs toward equality. We then discuss the present results’ implications for risk assessment and the prevention/treatment of IPH perpetration and victimization, as well as future research.

本研究旨在通过先进的三级荟萃分析方法，确定不同生态系统对IPH实施和受害相对于IPV、其他凶杀、IPH随后自杀和非虐待对照组的预测有效性。纳入了 29 项研究，在 16,237 名独特人群中产生了 473 项效应大小。每个因素都被分为三个生态系统之一：个体发生、微系统和外系统。结果显示，每个生态系统对 IPH 可能性的影响因犯罪者/受害者的性别和对照组而异。具体而言，在微系统水平上发现了亲密伴侣杀害女性 (IPF) 实施/受害与 IPV 的最大比值比，以及在风险因素的个体发育水平上发现了 IPF 受害与非受虐群体的最大比值比。主持人分析表明，男性 IPH 和 IPV 犯罪者在风险因素微系统水平影响方面存在差异，部分原因在于一套文化价值观和平等信念。然后，我们讨论目前的结果对风险评估、IPH 实施和受害的预防/治疗以及未来研究的影响。
