Heart rate (HR) and blood pressure (BP) were obtained by blood pressure monitor (Omron Healthcare, Inc., Lake Forest, IL). BrAC was measured via breathalyzer (Intoximeters Inc., St. Louis, MO). Two questionnaires were utilized to assess participants’ subjective response to the administered drug, the Profile of Mood States (POMS) and the Biphasic Alcohol Effects Scale (BAES). The POMS is a 72-item measure that assesses mood states (McNair, Lorr and Droppleman, 1971 ). Participants rate the extent to which they experienced each state using a 5-point scale. The responses have been factor analyzed into 8 scales: friendliness, anxiety, elation, anger, fatigue, depression, confusion and vigor, in addition to indexed scales of positive mood (elation minus depression) and arousal (anxiety plus vigor minus confusion plus fatigue). BAES was designed to measure the stimulant and sedative effects of alcohol (Martin et al., 1993 ). The BAES is a 14-item instrument that measures alcohol-induced stimulation (e.g. vigorous, elated, talkative) and sedation (e.g. sluggish, inactive, difficulty concentrating). Participants rated their subjective experience of the alcohol effects on an 11-point rating scale. Subjects also completed the Drug Effects Questionnaire (Morean et al., 2013 (link)) but these results were presented elsewhere (Murray, Weafer and de Wit, 2020 ).
