The B-BAES was developed using ratings of stimulation and sedation from the BAES at the ascending and descending limbs of the BrAC (Rueger et al., 2009). However, tests of its psychometric properties would also be important to establish at pre-drink baseline and peak BrAC (e.g., King et al., 2011a). Thus, the goal of Study One was to replicate and extend analyses of the B-BAES in an independent sample at four time points along the BrAC: baseline (−15 min), ascending limb (30 min), peak BrAC (60 min), and descending limb (120 min). We hypothesized for all four time points that (1) the same three B-STIM items (energized, excited, and up) and the same three B-SED items (sedated, slow thoughts, and sluggish) would be retained; (2) the six B-BAES items would demonstrate strong internal consistency reliability; (3) B-STIM and B-SED subscale scores would be significantly correlated with their respective full BAES scale scores, STIM and SED; and (4) confirmatory factor analysis would support models that demonstrate the distinctness of stimulation and sedation as predicted by theory.
