The participants were 600 men selected from 4 Kentucky State correctional facilities. Three prisons were medium-security facilities and one was a minimum-security facility. The participants volunteered for the study. Information came from personal interviewers conducted by trained interviewers and lasting approximately 2 hours. The analysis excluded the small number of men who reported perpetrating only intimate partner violence. Results indicated that the men who reported no violence were less antisocial than the others. They also were less involved with drugs and reported fewer emotional problems and less family conflict. In contrast, violent men generally reported more drug use, emotional problems, family conflict, and abuse victimization experiences than either those who perpetrated violence only against non-intimates or those who committed no violence. Findings suggested that a significant number of incarcerated, drug-using men pose a dual threat to the public and their partners and that targeting batterers within the correctional system for priority intervention could improve both partner and public safety.
