Shame and Self-compassion as Risk and Protective Mechanisms of the Internalized Weight Bias and Emotional Eating Link in Individuals Seeking Bariatric Surgery.

Emotional eating in bariatric surgery patients is inconsistently linked with poor post-operative weight loss and eating behaviors, and much research to date is atheoretical. To examine theory-informed correlates of pre-operative emotional eating, the present cross-sectional analysis examined paths through which experienced weight bias and internalized weight bias (IWB) may associate with emotional eating among individuals seeking bariatric surgery. We examined associations of experienced weight bias, IWB, shame, self-compassion, and emotional eating in patients from a surgical weight loss clinic (N = 229, 82.1% female, M. BMI: 48 ± 9). Participants completed a survey of validated self-report measures that were linked to BMI from the patient medical record. Multiple regression models tested associations between study constructs while PROCESS bootstrapping estimates tested the following hypothesized mediation model: IWB ➔ internalized shame ➔ self-compassion ➔ emotional eating. Primary analyses controlled for adverse childhood experiences (ACE), a common confound in weight bias research. Secondary analyses controlled for depressive/anxiety symptoms from the patient medical record (n = 196). After covariates and ACE, each construct accounted for significant unique variance in emotional eating. However, experienced weight bias was no longer significant and internalized shame marginal, after controlling for depressive/anxiety symptoms. In a mediation model, IWB was linked to greater emotional eating through heightened internalized shame and low self-compassion, including after controlling for depressive/anxiety symptoms. Pre-bariatric surgery, IWB may signal risk of emotional eating, with potential implications for post-operative trajectories. Self-compassion may be a useful treatment target to reduce IWB, internalized shame, and related emotional eating in bariatric surgery patients. Further longitudinal research is needed.
