Table 1 presents the characteristics for the 183 non-Asian females and 162 males used in these analyses, revealing no significant demographic differences. Time 1 alcohol and drug histories and SEM potential mediators (e.g., drinking to cope) were also generally similar across the sexes, except for higher maximum drinks, raw SRE scores (although the differences disappeared after adjusting for weight), and maximum peer drinking quantities, as well as more positive Global Positive Expectancies for males. At Time 2 males demonstrated higher drinking patterns and greater alcohol problems.
