A positive association between food addiction (i.e., an addiction to compulsively overeat highly palatable foods) and body dissatisfaction in college students exists. However, little is known about the underlying mechanisms. Eating expectancies, one's learning history regarding the association between eating and its consequences, may provide potential pathways linking food addiction and body dissatisfaction. In the current study, five eating expectancies (i.e., eating helps manage negative affect, eating is pleasurable and useful as a reward, eating leads to feeling out of control, eating enhances cognitive competence, and eating alleviates boredom) were evaluated as potential mediators between food addiction and body dissatisfaction in 738 college students (mean age = 19.21 ± 1.63, 61.4% female). Students completed the Eating Pathology Symptoms Inventory, Yale Food Addiction Scale, and Eating Expectancy Inventory. Adjusting for sex, age, race, and body mass index, structural equation modeling was used to examine the bi-directional mediation effects of the eating expectancies between food addiction and body dissatisfaction. Results showed a bi-directional positive association between food addiction and body dissatisfaction (β = 0.12-0.26, standard error [SE] = 0.07-0.03, all p < 0.01) that was partially mediated by the expectancy that eating leads to feeling out of control, regardless of whether body dissatisfaction was included as the independent or dependent variable (β = 0.15-0.36, SE = 0.05-0.02, all p < 0.01). Findings suggest the need to address the influence of expecting eating to lead to feeling out of control in interventions for co-occurring food addiction and body dissatisfaction among college students.
