Notes: All RRR are relative to the high school-only group. HS = high school; CI = confidence interval; GAD = generalized anxiety disorder.

^aMisclassified status reflects (1) families in which the mother reported at screening interview that the father was an excessive drinker but, at her full interview, did not report that the father met criteria for alcohol abuse or dependence (“false positives”) or (2) families in which the mother did not report at screening interview that the father was an excessive drinker but at full interview reported that the father met criteria for alcohol abuse or dependence (“false negative”). These were combined into one variable.

^bEarly alcohol use (before age 14 for European American, before 15 for African American), early marijuana (before 14), early tobacco (before 12).

^cFather’s education reported by mother.

^dHousehold income reported by mother, defined as a quasicontinuous measure reflecting 21 categories of income from no income to $150,000 or more.

^eEarly GAD, conduct, depression before age 15.

^fGrades in seventh grade by mother’s report, by quartile.

^†10 ≥p > .05;

*p < .05;

^**p < .01;

^***p < .001.
