Homicides followed by the suicide of the perpetrator constitute a serious form of interpersonal violence. Until now no study has directly compared homicide-suicides to other violent deaths from multiple countries, allowing for a better understanding of the nature of these violent acts. Using country-specific data, this study describes and compares the incidence and patterns of homicide-suicide as well as the relationship between homicide-suicide, homicide, suicide and domestic homicide in the Netherlands, Switzerland and the United States. The results indicate that cross-nationally, homicide-suicides are more likely than other types of lethal violence to involve a female victim, multiple victims, take place in a residential setting and to be committed by a firearm. Although homicide-suicides display many similarities across the different countries, differences exist regarding age and the use of firearms in the offence. This study indicates that homicides followed by suicides differ from both homicides and suicides in similar ways internationally. Cross-national differences in the availability of firearms may explain the international variation of homicide-suicide rates and patterns.
杀人后自杀的行为构成了一种严重的人际暴力形式。到目前为止，还没有研究直接比较过来自多个国家的杀人-自杀与其他暴力死亡，因此无法更好地了解这些暴力行为的性质。本研究使用特定于国家的数据，描述和比较了荷兰、瑞士和美国的杀人-自杀事件的发生率和模式，以及杀人-自杀与杀人、自杀和家庭杀人之间的关系。结果表明，跨国界而言，杀人-自杀比其他类型的致命暴力更有可能涉及女性受害者、多个受害者、发生在住宅环境中，并使用枪支。尽管杀人-自杀在不同国家之间存在许多相似之处，但在犯罪中涉及的年龄和使用枪支方面存在差异。本研究表明，杀人后自杀在国际上与杀人案和自杀案存在许多不同之处。不同国家枪支供应的差异可能解释了杀人-自杀率和模式的国际差异。
