Data analyses evaluated the pattern of SRE5 and SRET across the four time points for all 235 men from T15 through T30 using repeated measures ANOVAs. SRE values were corrected for outliers and some analyses focused on the subset of subjects in the upper and lower thirds of SRE scores, as small deviations from the mean of LR do not offer as clear information regarding future drinking outcomes (Schuckit and Smith, 1996; Schuckit et al., 2010, 2012b). The relationships of these SRE5 and SRET values to the most recent five-year pattern of drinking and related problems and to the alcohol challenge LR from ~age 20 were evaluated with Pearson Product-Moment correlations. Similar correlations were used to study the link between T15 SRE values and outcomes over the subsequent 15 years between T15 and T30; T20 SRE scores as predictors of the outcomes over the subsequent 10 years; as well as SRE scores from T25 as predictors of alcohol-related outcomes during the subsequent five years. Simultaneous multiple regression analyses were then used to evaluate how well the baseline alcohol challenge LR
