The item analysis showed that the same six items (energized, excited, sedated, slow thoughts, sluggish, and up) met criteria for retaining in the B-BAES in this independent sample (see Table 1). These items consistently showed the highest correlations with the total score and had the highest shared variance with the other items across all four time points. Cronbach’s alphas for energized, excited, and up ranged from .89 to .93 across all analyses, and for sedated, slow thoughts, and sluggish ranged from .90 to .91. Correlations between the corresponding subscale scores of the B-BAES with the full BAES across time points were very large in magnitude, ranging from .95 to .97 for B-STIM and STIM, and .92 to .96 for B-SED and SED. As was found in the initial evaluation of the B-BAES (Rueger et al., 2009), none of the correlations between the stimulation and sedation subscale scores across the four timepoints along the BrAC were statistically significant (rs ranging from −.04 to −.18 for B-BAES and .00 to −.14 for BAES). Analyses by sex revealed that the same six B-BAES
