Of the total sample, 2.5% (N=1,046) reported maternal only alcohol problems, 15.9% (N=6,859) reported paternal only alcohol problems, and 2.9% (N=1,265) reported both maternal and paternal alcohol problems. Of those with a maternal only history of alcohol problems, 22.2% (SE=1.6) met criteria for DSM-IV lifetime alcohol dependence. Of those with a paternal only history of alcohol problems, 20.9% (SE=0.7) met criteria for DSM-IV lifetime alcohol dependence. Of those with both maternal and paternal histories of alcohol problems, 35.0% (SE=1.7) met criteria for DSM-IV lifetime alcohol dependence. Of those with no parental history of alcohol problems, 9.6% (SE=0.3) met criteria for DSM-IV lifetime alcohol dependence (see Table 1).
