Overlap between suicidal behavior and interpersonal violence

Résumé

Suicidal behavior and interpersonal violence coexist in individuals to an extent that considerably exceeds chance covariation. Grasping the nature of this overlap enriches our understanding of suicidal behavior and that of interpersonal violence. The most extreme form of this overlap consists of homicide-suicide and the related concepts of mass murder, suicide bombing, and victim-precipitated homicide. The present chapter describes these phenomena and offers an overview of milder forms of coexisting suicidal behavior and interpersonal violence, organized by topical area: prospective studies, externalizing behaviors, neuropsychological factors, substance use disorders, trauma, protective factors, and exposure to violence. An overview of theoretical models follows. Implications of this body of knowledge for our understanding of suicidal behavior and suggestions for future inquiries conclude the chapter.
