Objective
Young adulthood, roughly ages 18–25, is a period of great risk for excessive consumption of alcohol, especially among sexual minority women. Despite the substantial literature examining the relationships between social norms and behavior in general, little attention has been given to the role of descriptive norms on the drinking behaviors of sexual minorities. The present study had three aims: to compare both typical woman descriptive norms and sexual minority-specific descriptive normative perceptions among a sample of sexual minority women, examine reciprocal associations between sexual minority-specific descriptive norms and alcohol consumption over time, and to examine whether these reciprocal associations were moderated by sexual orientation (i.e. whether one identifies as lesbian or bisexual).
Method
A national sample of 1,057 lesbian and bisexual women between the ages of 18–25 were enrolled in this study. Participants completed an online survey at four time-points that assessed the constructs of interest.
Results
Results indicated that sexual minority women consistently perceived that sexual minority women drank more than their non-sexual minority peers; sexual minority women-specific descriptive drinking norms and alcohol consumption influenced one another over time in a reciprocal, feed-forward fashion; and these associations were not moderated by sexual orientation.
Conclusions
These findings highlight the importance of considering sexual minority women-specific norms as an important factor predicting alcohol consumption in sexual minority women. Results further support the development and testing of normative interventions for high risk drinking among sexual minority women.
