The Transtheoretical Model of Change (TTM) predicts that matching interventions with a person's readiness to change should improve treatment outcomes. This cross-sectional correlational study examined characteristics that affected self-reported readiness to change abusive behavior among a sample of 109 men in a 52-week batterer treatment program. Participants completed measures of anger/hostility, readiness to change, manipulative parenting, and self-esteem. Results indicated that contemplation of the impact of abuse has the highest unique relationship with self-reported taking action to stop violence. Moreover, physical aggression and manipulative parenting account for significant variance in the scores associated with self-reported taking action to stop violence as well. These findings suggest that interventions aimed at moving clients into contemplation, and reducing physical aggression and manipulative parenting styles, may increase the likelihood that batterers will take action to stop violence.
