Personality characteristics, psychopathology, and other individual factors (e.g., motivation) are strongly associated with problematic drinking, but the extent to which these predict drinking behavior in a naturalistic setting, or how social aspects contribute to drinking behaviors in a diverse sample, is less understood. We sought to identify psychosocial variables linked to problematic alcohol use and examined real-time alcohol-related decision making in a naturalistic setting in a 2-day study involving a structured clinical interview, self-report measures, and an ad-lib social drinking task (following a 15-min mingling period, participants choose an alcoholic or non-alcoholic beverage to consume in a 30-min period). Fifty-one European American and African American community-based individuals (Mage = 23.78) in the Southeastern United States, classified as either “social” or “problematic” drinkers, participated. Those screening positively for major depression and antisocial personality disorder and those endorsing internal drinking motives reported greater problematic drinking. Individuals screening positive for major depression were more likely to choose alcohol in a social context, whereas impulsivity and social drinking motives were not predictive of beverage choice. Those engaging in social interaction during the social drinking task were more likely to choose alcohol regardless of initial preference. Results suggest social interaction not only influences drinking behavior, but impacts real-time decisions to drink alcohol, which is an area that has been largely overlooked in the literature.
