Background Low level of responses (low LRs) to alcohol established using the Self‐Report of the Effects of Alcohol (SRE) questionnaire are genetically influenced phenotypes related to heavy drinking and alcohol problems. To date, most studies using SREs focused on scores for the number of drinks needed for effects across the first 5 times of drinking (SRE‐5), and few evaluated scores that also included the prior 3 months and heaviest drinking periods (SRE‐T). This paper evaluates characteristics of SRE‐5 and SRE‐T within and across generations. Methods Data were extracted from 407 participants across 2 generations of 107 families in the San Diego Prospective Study (SDPS). Pearson's product–moment correlations for SRE‐5 and SRE‐T were determined across first‐degree relatives both within and across generations and sexes, as well as correlations of each measure to maximum drinking quantities and alcohol problems. Results Responding to 4 hypotheses, first the analyses demonstrated significant within‐generation positive correlations for both SRE measures across brother–brother and sister–sister pairs as well as cross‐generation correlations for fathers and sons, although correlations for mothers and daughters were not robust. Second, both SRE‐5 and SRE‐T correlated with maximum drinks and alcohol problems for both sexes and both generations. Third, within parental and offspring generations SRE‐T correlated more robustly than SRE‐5 to maximum drinks and alcohol problems. Fourth, across generations SRE values for sons were more closely related to drinking quantities and problems than for their fathers, but the mother–daughter SRE relationships to adverse alcohol characteristics were not different. Conclusions Both the SRE‐5 and SRE‐T offered useful information about propensities toward heavier drinking and alcohol problems in SDPS families. Correlations with adverse alcohol outcomes were greater for the more broad‐based SRE‐T, but both scores appeared to be genetically influenced and continue to operate in a robust manner in both generations of these families.
