Alcohol and social anxiety in women and men: pharmacological and expectancy effects

A replication study was conducted to determine pharmacological and expectancy effects of alcohol on self-reported anxiety in a social interaction situation. Thirty-two male and thirty-two female social drinkers were randomly assigned to four conditions in a 2 x 2 factorial balanced placebo design, controlling for drink content and expectations. Results show that in women alcohol expectancy reduced self-reported anxiety, whereas in men there was no significant effect of expectancy. Alcohol consumption reduced anxiety in both men and women. Controlling for beliefs increased some of the effects we found. We conclude that although cognitive factors do mediate the effects of alcohol on self-reported anxiety, this influence seems to be different for men and women and the role of pharmacological factors might be more crucial.
