Social Anxiety and the Quality of Everyday Social Interactions: The Moderating Influence of Alcohol Consumption.

Most research on the link between social anxiety and alcohol consumption has examined problematic outcomes without consideration of potential adaptive functions. Alcohol is an anxiolytic that has the short-term benefit of reducing anxiety; consumption may act as a social lubricant that facilitates higher quality social interactions. Using experience-sampling methodology, we examined how consuming alcohol attenuates the adverse effects of social anxiety in naturally occurring social interactions. Participants (N = 160) completed demographic and trait measures, then completed daily assessments for 14 consecutive days. Results from multilevel model analyses revealed that during face-to-face social interactions, state social anxiety was inversely related to 10 indicators of healthy social interactions (e.g., enjoyment, laughter, feelings of acceptance). Alcohol consumption moderated seven of these associations, such that when participants consumed alcohol in social situations, state social anxiety was no longer associated with social interaction quality. The quantity of alcoholic drinks consumed moderated two of these associations. Furthermore, we found evidence for directionality, such that social anxiety in a given social interaction predicted alcohol consumption in a subsequent social interaction, but not the reverse (i.e., alcohol consumption did not prospectively predict state social anxiety). In social situations that involved alcohol, experiences of social anxiety no longer thwarted one's ability to derive social benefits. These results should be interpreted in the context of a participant sample with relatively low levels of trait social anxiety and frequency of alcohol use. Nonetheless, obtaining social rewards may be a reinforcement mechanism that maintains the link between social anxiety and alcohol consumption.
