With limited exceptions, existing research has focused on either intrafamily violence or crime and violence outside the family. This study examined the proportion of men who only offend extrafamilially, the proportion of men who are violent only towards their wives, and the proportion of men who are violent in both spheres. Unincarcerated males (N=2,291) were interviewed over the telephone regarding any violence towards their wives and any violent behavior toward individuals who were not in the family. Subjects, a subsample of the 1985 National Family Violence Survey respondents, were comprised of those men who were currently or recently living with a spouse or female partner, and had responded to a series of questions designed to assess the existence or absence of assaultive behavior. Results indicated that 15% of the men in this sample had engaged in some form of violent behavior over the past year. The majority of violent males specialized in their choice of victims; that is, they chose to assault only family or non-family members, but not both. Only 10% of the violent males reported assaulting both family and non-family individuals; 75% of the violent men admitted assaulting their wives within the previous year; and 33% admitted to non-family assault.
