Participants completed the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA; Bucholz et al., 1994; Hesselbrock et al., 1999) with a trained research interviewer. As part of this interview, participants were asked whether one or two drinks had ever caused them to (a) flush or blush; (b) feel very sleepy; (c) have headaches or head pounding/throbbing; (d) have nausea; (e) have heart palpitations; or (f) break out into hives. A total score was created by summing the number of symptoms endorsed (range 0-6).
