Abstrakt: Up to a third of service members and Veterans experience disordered eating. Disordered eating can be maintained through negative reinforcement of painful and unpleasant emotions such as guilt, shame, sadness, and hostility. Hostility is a negative emotion that may be particularly relevant for service members and Veterans, yet hostility's relation to disordered eating remains understudied. Further, variability in emotions may be particularly relevant, given that variability in emotions is often a stronger predictor of psychopathology than mean levels. Thus, the goal of the present study was to assess a potential bidirectional relationship between disordered eating symptoms and individuals' variability of hostility, stress, anxiety, sadness, and shame. Participants (N = 94, M age  = 32.2, 75.8% men; 81.8% White) completed 30 days of ecological momentary assessment (EMA) with four assessments per day along with baseline and follow-up measures including the Eating Pathology Symptom Interview (EPSI), which assessed eight disordered eating symptom domains. Hierarchical regressions revealed that higher baseline levels of Binge Eating and Excessive Exercise predicted greater intraindividual hostility variability. Further, more hostility variability predicted higher Cognitive Restraint at 1-month follow-up. Baseline disordered eating symptoms were not associated with intraindividual variability in stress, anxiety, sadness, or shame. However, greater intraindividual variability in shame predicted higher Muscle Building at 1-month follow-up. Hostility variability was the only emotion that was predicted by, and predictive of, disordered eating symptoms. These findings suggest that hostility may be a relevant treatment target for service members with disordered eating.
