Eating disorders (EDs) are a serious public health concern, affecting about 5.2% of American women. The effects of negative affect on problem-solving and its psychophysiological correlates are poorly understood in this population. This study examined respiratory sinus arrhythmia (RSA) and skin conductance responses of 102 women with EDs (Binge eating disorder [BED]: n = 57, Anorexia nervosa: n = 13, Bulimia nervosa [BN]: n = 32) and 24 healthy controls (HCs) at baseline, and then during: a negative mood induction task, an adapted Means Ends Problem-Solving (MEPS) task and recovery. The MEPS Task included four interpersonal scenarios: 1) binge-eating when sad, 2) job dissatisfaction, 3) feeling rejected by friends, and 4) jealousy in a relationship. ED groups reported more negative and less positive emotions than HCs. After a negative mood induction, women with BED provided significantly less effective problem-solving strategies compared to HCs and women with BN for the binge-eating MEPS scenario. Relative to baseline and the negative mood induction, all participants exhibited significantly higher skin conductance response and skin conductance levels throughout the MEPS scenarios and recovery. BED showed significantly lower RSA ...Continue Reading

BioRxiv & MedRxiv Preprints

BioRxiv and MedRxiv are the preprint servers for biology and health sciences respectively, operated by Cold Spring Harbor Laboratory. Here are the latest preprint articles (which are not peer-reviewed) from BioRxiv and MedRxiv.

Anorexia Nervosa

Anorexia nervosa (AN) is a psychiatric condition characterized by severe weight loss and secondary problems associated with malnutrition. Here is the latest research on AN.


Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
