BACKGROUND: The utility of one of the most widely used subjective alcohol assessment tools, the Biphasic Alcohol Effects Scale (BAES) has been somewhat limited based on lack of psychometric studies in large and diverse samples, a range of alcohol doses, the length of the measure, and the original instructional set which precluded baseline measurement and disclosed to subjects that they received alcohol. METHODS: The current study investigated the factor structure of the BAES with a modified instructional set at pre-drink baseline and after consumption of various doses of alcohol, in a sample of 190 men and women, heavy and light social drinkers. This study tested the psychometric properties of a brief version of the BAES (Brief-BAES or B-BAES). RESULTS: Results demonstrated robust support of the stimulant and sedative constructs across all conditions, and demonstrated strong psychometric support for the 6-item B-BAES. DISCUSSION: This is the first comprehensive study to expand the utility of the BAES by instructional set, baseline measurement, at various alcohol doses, and by drinking history and sex. In addition, the introduction of the B-BAES may further increase the utility of this scale, particularly in paradigms with repeated measurement or time constraints.
