Note. Gender was coded 0 (Male) and 1 (Female). Ethnicity was coded 0 (Chinese) and 1 (Korean and Japanese). ALDH2 and ADH1B were coded 0, 1 or 2 corresponding with number of variant (*2) alleles. CEOA = Comprehensive Effects of Alcohol Questionnaire Pos = Global positive expectancies Neg = Global negative expectancies. PEAQ = Physiological Effects of Alcohol Questionnaire (total score). (E) = Expectancy evaluation component.
