The intergenerational transmission of domestic violence is most commonly studied from the perspective of social learning theory, with the consequence that variables external to that perspective are often overlooked. This study was undertaken in an effort to broaden the theoretical basis of intergenerational transmission of domestic violence by assessing if incorporating variables from attachment theory (measures of separation and loss) with exposure to violence in family of origin would increase predictive power of a multiple regression model. Subjects ( N = 74) were men in treatment for domestic violence. Separation and loss variables were found to exert effects on respondents’ violent behavior greater than or comparable to those from exposure to family of origin violence. Findings supported a need to broaden theoretical views of the etiology of domestic violence perpetration.
