Self-Reported Effects of Alcohol (SRE): SRE is an instrument used in numerous studies to assess level of response. SRE scores taken over a year apart have 0.82 correlation (ranging from 0.60 to 0.99) showing high test/retest reliability (Schuckit et al., 1997a). The SRE, completed during screening and interview, assessed the indices of early alcohol use (SRED), regular alcohol use (SRRD), and heavy alcohol use (SRHD). SRE produced 12 possible cells of data – 3 periods of drinking (early, regular, and heavy) by 4 physiological effects of drinking (feeling different, slurring speech, begin stumbling, and pass out when not want to). Each score was an average, generated by dividing the total number of standard drinks reported in cells of a particular period, by the number of cells of physiological effects endorsed within that period. A standard drink was the equivalent of 13.6gm of alcohol such as 12oz beer, 5–6 oz table wine or 1.5oz 80-proof spirit. Outlying SRE scores were unadjusted in the analysis. Total effect score (SRTT) was the mean score obtained by adding the number of drinks from the
