Psychologic and physiologic reactivity to stressors in eating disordered individuals

The present study explored a potential mechanism for the relationship between stressors and binge eating: specifically, whether subjects with behaviors and attitudes reflecting disordered eating show distinctive psychologic or physiologic reactivity to stressors. Female undergraduates participated in a laboratory study involving four psychologically stressful tasks. Blood pressure and pulse rate were monitored, and several psychologic questionnaires were administered. Analyses revealed that the tasks provoked significant cardiovascular and affective responses in both high- and low-disordered eaters. There were no differences between groups in cardiovascular responsivity or mood state in response to diverse stressors. However, those with more disordered eating reported an increased desire to binge in response to the stressors, along with more global stress, lower self-esteem, and lower mastery than the comparison group. The results suggest that the increased desire to binge in response to stressors reported by subjects higher in disordered eating cannot be accounted for by differences in cardiovascular reactivity or negative hedonic state, relative to what subjects low in disordered eating showed in response to the same stressors.
