Impulsiveness, impulsive aggression, personality disorder, and spousal violence.

Impulsiveness has become a key concept in thinking about the determinants of violence and aggression. In this study of spouse abusers, the relationship between impulsiveness, impulsive aggression, and physical violence is confirmed. Impulsiveness and impulsive aggression have significant correlations with physical aggression. Impulsiveness and impulsive aggression are also correlated with measures of Borderline Personality Disorder and Antisocial Personality Disorder. In addition, the measures of Borderline and Antisocial Personality Disorder (PD) are significantly correlated with physical aggression. The violent and non-violent groups differed on impulsive aggression and on Borderline Personality Disorder. A partial replication of Tweed and Dutton's findings (1998) revealed sub-groups of high- and low-violence men. The high-violence group was very different from the low-violent and the non-violent groups. The high-violence group had higher pathology scores on all clinical scales, except Mania, of the Personality Assessment Inventory. These findings have implications for violence prediction and for treatment of violent men.
