Mean internalizing sum scores for each wave are provided in Table 1. Internalizing scores were higher for children of mothers with a history of depression (t-statistics ranging from 5.99 to 8.02, p<0.0001). Internalizing scores and family income were inversely related (F-statistics ranging from 10.35 to 12.38, df=4, p<0.0001). Details on alcohol use are provided in Table 2; note that only binge drinking and past 6 month alcohol use variables were included in subsequent analyses. Correlations between binary alcohol use outcomes (excluding the stem item “Have you ever had a full drink?”) ranged from 0.42–0.85. Age at initiation was modestly inversely correlated (−0.07 – −0.03) with the other alcohol outcomes.
