Abstract

Introduction: The objective of this study was to compare jealousy as a correlate of intimate partner homicide-suicide cases to homicide-only cases using data from the National Violent Death Reporting System (NVDRS), a state-based surveillance system maintained by the Centers for Disease Control and Prevention. Jealousy is categorized as jealous feelings or distress over a current or former intimate partner's relationship or suspected relationship with another person.

Methods: NVDRS data from a 5-year period (2016-2020) was used to estimate frequencies and identify significant differences in jealousy and other sociodemographic, mental health, relationship, and incident-related correlates of intimate partner homicide-suicide compared to homicide-only cases. Cases were included if they involved an intimate partner single homicide or a single homicide followed by suicide.

Results: The study sample included 5335 cases (intimate partner homicide-suicide n = 1402; homicide-only n = 3933). A significantly higher percentage of intimate partner homicide-suicide cases reported jealousy preceding the event (9%) compared to homicide-only cases (6%). Compared with homicide-only cases, homicide-suicide cases had 3.5 greater odds of recording jealousy as a precipitating event.

Conclusion: Findings suggest that intimate partner homicide-suicide cases are distinct from homicide-only cases both in terms of individual- and incident-level and situational factors, including the presence of jealousy.

嫉妒是亲密伴侣杀人-自杀与单纯杀人案件的关联因素：全国暴力死亡报告系统，2016-2020年。

导言本研究旨在利用美国疾病控制与预防中心（Centers for Disease Control and Prevention）维护的国家暴力死亡报告系统（National Violent Death Reporting System，NVDRS）中的数据，将嫉妒作为亲密伴侣杀人-自杀案件与纯杀人案件的相关因素进行比较。嫉妒被归类为因现任或前任亲密伴侣与他人的关系或疑似关系而产生的嫉妒情绪或痛苦：方法：利用为期 5 年（2016-2020 年）的 NVDRS 数据来估算嫉妒的频率，并确定与纯凶杀案相比，亲密伴侣杀人-自杀案在嫉妒及其他社会人口学、心理健康、人际关系和事件相关因素方面的显著差异。如果案例涉及亲密伴侣单人杀人或单人杀人后自杀，则将其纳入研究范围：研究样本包括 5335 个案例（亲密伴侣杀人-自杀 n = 1402；纯粹杀人 n = 3933）。与纯他杀案件（6%）相比，亲密伴侣杀人-自杀案件中报告案发前嫉妒的比例明显更高（9%）。与纯杀人案件相比，杀人-自杀案件中将嫉妒记录为诱发事件的几率要高出 3.5 倍：研究结果表明，亲密伴侣杀人-自杀案件在个人和事件层面以及情境因素（包括嫉妒的存在）方面均有别于纯粹的杀人案件。

期刊介绍： An excellent resource for researchers as well as students, Social Cognition features reports on empirical research, self-perception, self-concept, social neuroscience, person-memory integration, social schemata, the development of social cognition, and the role of affect in memory and perception. Three broad concerns define the scope of the journal: - The processes underlying the perception, memory, and judgment of social stimuli - The effects of social, cultural, and affective factors on the processing of information - The behavioral and interpersonal consequences of cognitive processes.
