Note. Abbreviations within the table are SEAS = Subjective Effects of Alcohol Scale; BAES Stim./Sed. = Stimulant or Sedative Subscale of the Biphasic Alcohol Effects Scale; SHAS = Subjective High Assessment Scale; HIGH− = high arousal negative; LOW− = low arousal negative; HIGH+ = high arousal positive; LOW+ = low arousal positive. Step 1 variables included sex, BAES stimulation, BAES sedation, and the SHAS for all models. The typical number of drinks consumed per drinking occasion were included in Step 1 for the models assessing driving after drinking and alcohol problems. Step 2 variables were the SEAS subscales (absolute or change from baseline).
