<p>Although intimate partner violent men have been found to be different from non-violent men on a number of variables, little research has compared partner violent men to men who engage in violence outside of relationships. The present research explored the similarities and differences between men with and without a history of physical partner violence within a sample of high risk violent men who attended New Zealands' High Risk Special Treatment Units. Pre-treatment psychopathology, measured on the Millon Clinical Multiaxial Inventory III (MCMI-III;Millon, Davis, & Millon, 1997) was compared between these two groups and few differences were found. Comparisons on criminal history, criminal risk and change in dynamic risk also revealed no significant differences between these two groups. This research also explored whether similar or different psychopathology subtypes exist among men with and without a history of intimate partner violence. A latent profile analysis was conducted to examine psychopathology subtypes, and the proportions of men with and without a history of partner violence within each subtype were compared. The results showed that there were similar proportions of men from both groups within each of the subtypes, suggesting that men with and without a history of intimate partner violence share similar psychopathology profiles. The likelihood of reconviction or reimprisonment within 1 year of release from prison was also comapred between men with and without a history of intimate partner violence. The two groups were found to be reconvicted at a similar rate for any offence, violent offences, and were at a similar likelihood of being re-imprisoned. To conclude, the results suggest some similarity between men with and without a history of intimate partner violence, but future research should explore a wider range of factors that may distinguish between these two groups and inform whether men who engage in partner violence are unique from men who engage in other forms of violence.</p>
