This study assessed the contribution of the men's stage of change to the prediction of attrition among men attending a batterer treatment program. As outlined by the transtheoretical model of change, men were classified into the precontemplation, contemplation, or action stage based on their level of change motivation and behavior. It was hypothesized that men in the precontemplation stage would dropout of treatment at higher rates than men in later stages of change. Participants were 308 men who enrolled in a batterer treatment program over the course of 1 year, 61.4% of whom dropped out of treatment. Counselor rated, but not self-rated stage of change significantly predicted treatment completion once traditionally used demographic, contextual, and personality variables were taken into account. Specifically, men identified by counselors as being in the precontemplation stage were 2.3 times as likely as men rated in the contemplation stage and 8.8 times as likely as men rated in the action stage to dropout of treatment. Referral source, age, and history of arrest also made significant contributions to the prediction of attrition. The best combination of predictors led to the successful classification of 72% of the cases, 98% of the dropouts but only 19% of the completers. Discussion focuses on the limitations of current findings and their implications for the use of the transtheoretical model to predict attrition from batterer treatment.
