Alcohol and drug use in the home is also a high risk correlate, as are employment and financial difficulty within the family. Social isolation is another common vulnerability for the victim. Rigid family roles favoring male dominance and control and/or intergenerational histories of abusive relationships both significantly increase the chances for DV. Several research studies have focused on DV among specific ethnic minority groups but differences diminish when variables such as income, education, and stress factors are controlled.
