Note. HDE = Heavy Drinking Episode. Cohen’s drm = mean effect size difference controlling for the correlation between repeated measures of the same variable. Effect sizes with confidence intervals that include 0 are considered non-significant. n = 51 for Drinks Per Week and HDEs, n = 50 for Alcohol-Related Problems.
