General versus hunger/satiety-specific interoceptive sensibility in predicting disordered eating
Even though derangements in the interoceptive signal processing of satiety and hunger play a significant role in abnormal eating behaviors, they continue to be evaluated using general evaluations of interoceptive sensibility (IS; how individuals personally account for their internal physical cues). Generalized measurements of IS include cues from several physiological systems, such as cardiac and gastric cues, thus, in this study by Poovey et al. (2022), the authors attempted to evaluate hunger and satiety-specific IS in a population of 213 participants (mean age = 20.77 years, 50% females). The participants submitted a series of online evaluations to measure IS, including the Multidimensional Assessment of Interoceptive Awareness-2 (general), the Intuitive Eating Scale-2 (hunger/satiety-specific), and the Eating Disorder Inventory Interoceptive Awareness Subscale (general), in addition to the Eating Pathology Symptoms Inventory to evaluate potential eating attitude or behavior derangements in the participants. After controlling for variables, analysis of the results revealed a relationship between hunger/satiety-specific IS and purging, binge eating, and cognitive restraint, demonstrating superior prediction over conventionally used general IS measures. It was noted, however, that hunger/satiety-specific IS could not be used as a predictor of restriction pattern eating behaviors. The authors conclude by discussing how derangements in the interoceptive processing of hunger and satiety signals could present a substantial target for treatment interventions and screening endeavors in the management of disordered eating behaviors, and the significance of selecting appropriate IS measurement methodologies.
