When cross-generation correlations of SRE scores with maximum drinks and alcohol problems were broken down by sex, most of the cross-generation findings were explained by father-son pairs, with only non-significant mother-daughter differences. Potential explanations for these sex differences might be the higher absolute values for drinking quantities and problems in males which resulted in a wider range of values for correlations, or potential cross-generational sex-related differences in attitudes such as levels of permissiveness for heavier drinking in males versus females (McCabe, 2002; Nichol et al., 2007; Salvatore et al., 2017; Weisbeck, 2003). Such possibilities are supported by data regarding secular trends in the lifetime prevalence of heavy drinking and alcohol problems (Grucza, et al., 2008) and cohort effects for drinking practices over the years (Kapoor et al., 2017). Also, sex differences in attitudinal influences (e.g., the impact of heavier drinking peers and more positive alcohol expectancies) might help explain the greater relationship of a low LR to heavier drinking in males in the younger generations as the impact of heavier drinking peers and more positive alcohol expectancies have been shown
