Abstract

BACKGROUND: Gastric interoception (i.e., the perception of gastrointestinal signals such as hunger, satiety or nausea) in the context of eating has recently gained increasing research attention. Nevertheless, it remains poorly understood how different interoceptive dimensions (e.g., self-report) and organ systems (e.g., cardiac, gastric) relate to each other and to disordered eating behaviors such as emotional, external and restrained eating. We assessed multiple dimensions (behavioral, self-reported, and physiological) in the cardiac domain (interoceptive accuracy, interoceptive self-report, interoceptive insight and objective physiological state) and in the gastric domain (gastric interoceptive sensitivity, gastric attribution of interoceptive sensations, interoceptive self-report, interoceptive insight and objective physiological state). The first goal of this study was to examine the relationship between cardiac and gastric interoception measured via multiple dimensions (behavioral, self-reported, and physiological). The second goal was to investigate whether multidimensional gastric interoception was a more important predictor of emotional, external and restrained eating than multidimensional cardiac interoception.
