Gender Differences in Normative Misperceptions of Food and Alcohol Disturbance Among a Multi-Site Sample of College Students.

Background: Engagement in food and alcohol disturbance (FAD; e.g., restricting caloric intake in the context of using alcohol to quicken/increase intoxication [FAD-intoxication] and/or to offset calories consumed from alcohol [FAD-calories]) confers risk to college students. Much research suggests that students overestimate the frequency of high-risk drinking among their peers, leading to greater participation in personal high-risk drinking. However, limited work has examined social norms related to FAD and their association with FAD behaviors. Objectives: The present study investigated: (a) whether normative misperceptions exist for FAD, (b) whether FAD norms are associated with FAD behaviors, and (c) whether gender moderates the association between FAD norms and FAD behaviors. Participants were 1,499 college students from six universities who consumed alcohol in the last month and identified as a woman or man. A plurality of participants identified as being White, non-Hispanic (59.5%) and female (68.1%), with a mean age of 19.66 (SD = 2.09) years. Results: Analyses revealed that students overestimated the frequency and approval of both FAD-intoxication and FAD-calories behaviors among their same-gender peers. Notably, these misperceptions were greater for FAD participators compared to FAD abstainers. Moreover, the associations between FAD norms and FAD behaviors were generally stronger for women compared to men. Conclusions: Our preliminary findings identify social norms as a potential target for interventions aiming to reduce FAD among college students. Further, our results provide preliminary evidence that college women, especially those who engage in FAD, may reap the greatest benefit from interventions targeting normative misperceptions (e.g., personalized normative feedback) related to FAD.
