Analyzed by ANCOVA of Visual Analog Scale (VAS) scores for each subscale (Desire for Alcohol, Perceived Stress) at Post-Noise and Post-Drinking, controlling for session (Pre-Noise) baseline.
Stress (Present, Absent); Word Type (Alcohol, Neutral); Treatment Condition (Combined: Active Stress + Test Drink on same session; Separate: Active Stress and Test Drink on separate sessions); and Drink Group (Test Drink: Alcohol vs. Placebo Beer; P-Beer).
