Suicidal and violent behavior: The role of anger, emotion dysregulation, and impulsivity

• Suicidal and violent behavior are related to anger.
• Emotion dysregulation mediated the anger–suicidal behavior relationship.
• Negative and positive urgency mediated the anger–violent behavior relationship.

Suicidality and violence are serious public health problems. A rich literature supports the relationship between suicidality and violence, including common associations with trait anger. However, less is known about how trait anger may facilitate these behaviors. Two potential mechanisms in this relationship are emotion dysregulation and impulsivity, both of which are linked to increased anger, suicidality, and violence. We investigated anger as a common underlying factor for both suicidal and violent behavior, and emotion dysregulation and impulsivity (i.e., negative and positive urgency) as potential mediators in this relationship. Results demonstrate that trait anger was associated with both suicidal and violent behavior. Further, emotion dysregulation mediated the anger and suicidal behavior relationship whereas both negative and positive urgency mediated the anger and violent behavior relationship. Although trait anger may be a common underlying factor for both suicidal and violent behavior, the nature of these relationships seems to vary significantly.
