Reactive aggression and suicide - Theory and evidence

Aggression confers risk for suicide. However, "aggression" is a heterogeneous construct, and it is likely that subgroups of individuals with particular types of aggression are at higher risk. We postulate that a subtype of aggression, reactive aggression, underlies the link with suicide with implications for suicide risk-recognition and prevention. The theoretical rationale and empirical evidence for the role of reactive aggression in suicide is presented from the perspectives of neurobiology, psychopathology, and overt violent behavior. It is hypothesized that partner-relationship disruptions amplify risk for suicide in the near term among reactive aggressive individuals, particularly those with psychiatric disorders, and preliminary evidence in support of this hypothesis is reviewed. We also discuss being jailed as a potential precipitant of suicide in reactive aggressive individuals. Recommendations are made to advance the study of reactive aggression and suicide, including methodological innovations and a greater focus on research of women and older adults.
