Bivariate statistics are presented in Table 1. Overall, 36 % of respondents in the analysis sample met criteria for alcohol dependence. About 36 % of subjects with alcohol dependence carried the high-risk genotype at GABRA2 compared to 30 % of those without alcohol dependence (X2 = 8.43, 1 df, p < 0.01). The percent of men and women in the sample with the high-risk genotype at GABRA2 was approximately equal (32 %). However, ignoring genotype, men were significantly more likely to have alcohol dependence than women (51 vs 23 %, X2 = 190.40, 1 df, p < 0.001). Compared to individuals without alcohol dependence, affected individuals reported higher mean daily hassles (0.76 vs 0.66, t = −5.77, p < 0.001) and lower mean daily uplifts (0.98 vs 1.01, t = 2.07, p < 0.05). Overall, mean negative and positive daily life events did not differ significantly by gender.
