The Predictive Utility of Psychological Aggression for Intimate Partner Violence.

Although psychological aggression has been identified as a risk factor for physical aggression, the prevalence of psychological aggression is much higher than that of physical aggression. To further understand the relationship between psychological and physical aggression, the level of psychological aggression at which physical aggression becomes more likely was evaluated. A representative sample of 268 men and 299 women responded anonymously to a self-report measure of aggression (revised Conflict Tactics Scale [CTS-2]) at baseline, and then 1 year later. Using both cross-sectional and longitudinal analyses, this study evaluated the level of psychological aggression that is necessary before it is likely that one will be physically aggressive. When one was at the 80th percentile of psychological aggression, there was a 70% probability that a man would be physically aggressive and 85% probability that a woman would be physically aggressive. Longitudinally, when one was at the 80th percentile of psychological aggression at Time 1, there was a 40% probability that a man would be physically aggressive and 45% probability that a woman would be physically aggressive at Time 2. CTS-2 psychological decile scores are provided along with the probability of physical aggression to assist clinicians in interpreting client scores. Implications for research and couples therapy are discussed. [ABSTRACT FROM AUTHOR]
