Turning to alcohol-related variables in the lower portion of Table 1, within generations both SRE-5 and SRE-T values were higher in males than females (i.e., males reported needing more drinks for effects, or a lower LR per drink). Similarly, within each generation, males reported higher lifetime maximum drinking quantities, more of the 11 DSM-IV alcohol problems (American Psychiatric Association, 1994), and were more likely to fulfill criteria for lifetime alcohol dependence or abuse. These drinking figures are for lifetime up to the time of the interview used here.
