title: Beyond personality-experimental investigations of the effects of personality traits on in situ alcohol consumption in social and solitary drinking contexts.
abstract: Numerous studies have highlighted that personality traits are associated with alcohol problems and disorders; however, little is known on the link between personality and the quantities of alcohol actually ingested during given drinking episodes (i.e. in situ alcohol consumption, in grams of pure alcohol). Based on data of 123 young adults who participated in two wine-tasting assignments (one performed in group, the other individually; sequence of participation assigned at random), the results from regression models suggest that individual characteristics and personality traits are, to some extent, associated with in situ alcohol consumption, but contextual factors (e.g., in line with behavioral exposition and perceptions of norms) might overwhelm such associations in a social context, or later on in similar drinking contexts. These findings argue for the development of early preventive initiatives focusing on social influences and on specific drinking context.
