Abstract
Internalizing symptoms (depression, anxiety, and self-esteem) have been repeatedly associated with Food and Alcohol Disturbance (FAD) in cross-sectional studies. FAD refers to a maladaptive pattern linking disordered eating and alcohol consumption, driven by alcohol enhancement and/or caloric compensation motives. However, cross-sectional studies do not allow for the examination of temporal or within-person dynamics, leaving unclear how internalizing symptoms and FAD influence each over time. This study examined longitudinal associations between FAD motives and internalizing symptoms using random-intercept cross-lagged panel models across three annual waves in a French university sample of 256 students. At the between-person level, no stable associations emerged between FAD and internalizing symptoms. At the within-person level, alcohol enhancement motives predicted higher anxiety, while both FAD motives predicted short-term decreases in self-esteem. Caloric compensation motives predicted later increases in depressive symptoms. Elevated depression predicted disengagement from FAD behaviors. FAD motives show distinct temporal relationships with internalizing symptoms, while increasing depressive symptoms may reduce motivation to engage in appearance- or enhancement-driven FAD behaviors. These findings highlight the importance of considering the functional role of FAD motives in relation to internalizing symptoms and suggest that these behaviors may reflect distinct maladaptive coping processes in students. Future research should consider the role of contextual factors such as stress, use more ecologically approaches (e.g. ecological momentary assessment), and examine whether these dynamics are also observed in clinical populations with alcohol use or eating disorders.
