Regarding other predictors, we found significant family history and gender main effects. Consistent with the report from the parent study (Kerfoot et al., 2013), which utilized the full sample of 180 participants, we did not find a family history by dose condition by timepoint interaction. In the present study, irrespective of timepoint, family history positive individuals reported significantly less sedation than family history negative individuals; and males reported more stimulation than females. Given the lack of significant interactions, it is difficult to know whether these results are attributable to family history status or gender differences in subjective response, alcohol-related expectancies or some other response tendency. Thus, these results regarding family history and gender should be interpreted with caution.
