Abstract

We examined the effects of drinking alcohol at the time of a social event on later post-event processing among socially anxious individuals. A sample of 84 (43 males, M age = 21.36 years, SD age = 2.06) undergraduates were randomly assigned to an alcohol (n = 44; mean blood alcohol concentration = .057 %), or a no alcohol (n = 40) condition. Following beverage consumption and absorption, they participated in a social interaction with an opposite-gendered confederate. Four days later, participants completed a measure of post-event processing of this interaction. A significant beverage condition by gender interaction was observed on levels of post-event processing: post-event processing levels were lower in the alcohol versus the no alcohol condition for females, whereas they were higher in the alcohol versus the no alcohol condition for males. This pattern of alcohol reinforcement might help explain observed gender differences in the odds of alcohol use disorders in social anxiety disorder.

All study procedures were the same as those reported in Battista et al. (2012) as data was collected for both studies at the same time. The results presented in Battista et al. (2012) examined how alcohol affected participant behaviors during the social interaction whereas the current study focused on data that was collected 4 days after the social interaction (i.e., post-event processing).

The full, 13-item version of the PEP had a lower internal consistency (α = .66) than the modified 12-item version, and the alpha of the full 13-item version was below the commonly accepted cutoff of α = .70, further justifying the exclusion of this item from the total score calculation.

On average, participants completed the PEP approximately four days (M = 3.74, SD 1.49; range 3–10 days) after completing the lab-based portion of the study. A 2 × 2 ANOVA revealed no significant main or interactive effects of beverage condition or gender on the time elapsed between completing the study and completing the PEP measure.

Given that men had significantly greater levels of typical drinking (measured with the DDQ) at baseline and there were two other gender differences that approached significance (i.e., scores on the RAPI and BAC levels after the social interaction), we re-ran our main analysis using an analysis of covariance (ANCOVA), controlling for scores on the DDQ, RAPI, and Social Interaction BAC. Since results did not change, we have reported only the original ANOVA in the main text for the sake of simplicity and parsimony.
