Table 1.

The light and the hazardous drinkers were equivalent in terms of age, gender, depression [Beck Depression Inventory (BDI)-II scores], anxiety [State-Trait Anxiety Inventory (STAI)-trait and STAI-state scores], and impulsivity [Urgency Premeditation Perseverance and Sensation Seeking Impulsive Behavior Scale (UPPS) total score] (all p’s > 0.05). The two groups differed solely on alcohol variables: the Alcohol Use Disorders Identification Test - Alcohol Consumption questions (AUDIT-C) subscore [t(47) = −10.836; p < 0.001], the mean number of alcohol doses per drinking occasion (ADO), the mean number of drinking occasions per week (DOW), and the mean number of alcohol doses per week (ADW).
