Comparison of impulsive and premeditated perpetrators of intimate partner violence.

Violence occurs in four to five million intimate relationships each year in the United States. Past research has investigated the concept of batterer subtypes based on the nature of the violent behavior. To extend this research, the present study used the Impulsive/Premeditated Aggression Scale (IPAS) along with a battery of relevant self-report measures in a sample of men (N = 113) convicted of domestic violence and court ordered into an intervention program. Batterers whose violence was classified as premeditated scored higher on psychopathic traits and a measure of treatment rejection. Batterers whose violence was classified as impulsive in nature reported a wider range of serious psychopathology. It is suggested that the use of a bimodal classification (Impulsive/Premeditated) in batterers may have significant clinical and legal policy implications. Copyright (c) 2008 John Wiley & Sons, Ltd.
