The main dependent measures for alcohol response in this report were the brief stimulation (B-STIM) and sedation (B-SED) subscales from the Brief Biphasic Alcohol Effects Scale (B-BAES) (34,35) and items from the Drug Effects Questionnaire (36) for like (“I LIKE the effects I am feeling right now”), with the midpoint indicating neutral, and want more (“I would like MORE of what I consumed right now”). On the basis of our previous work (16), net change scores were computed for stimulation and sedation as the rating at peak BrAC (60 minutes) from baseline, minus the same change score in the placebo session; for liking and wanting, net change scores were the 60-minute rating for alcohol minus placebo because there was no baseline. Secondary measures included similar net change scores at rising (30 minutes) and declining (120) BrAC limb as a direct test of the differentiator model. Participants were asked to respond on the basis of their current feeling state; the beverage content was not divulged.
