Boredom proneness, interoception, and emotional eating

Emotional eating is associated with weight gain and difficulty losing weight during weight loss interventions. Theoretical and empirical work suggest boredom may be an important predictor of problematic eating behaviors. Yet, little work has examined the role of boredom in emotional eating. Further, individual differences in the ability to recognize internal cues (i.e., interoception) may alter the impact of boredom on emotional eating. This study hypothesized that boredom proneness would predict unique variance in emotional eating after accounting for negative and positive affect, and that the association between boredom proneness and emotional eating would be stronger among those with poorer interoceptive ability compared to those with better interoceptive ability. Hypotheses were tested in two large samples using multiple linear regression. Participants aged 18-65 were recruited from MTurk (n = 365; 59.2% female) and an undergraduate research pool (n = 461; 52.9% female). Participants completed self-report measures: Boredom Proneness Scale; Dutch Eating Behavior Questionnaire- Emotional Eating; Multidimensional Assessment of Interoceptive Awareness-2; Intuitive Eating Scale-2- Reliance on Hunger and Satiety Cues; and Positive and Negative Affect Schedule. Boredom proneness was a significant predictor of emotional eating in both samples, even accounting for the broad dimensions of negative and positive affect (ps < .001). Interoception did not moderate the association between boredom proneness and emotional eating in either sample (ps > .05), but was an independent predictor of emotional eating (ps < .001). Boredom proneness and interoceptive ability may warrant attention as targets in the prevention and treatment of emotional eating. Future work should continue exploring different emotion categories and different facets of interoception in emotional eating, as well as examine novel mechanisms that could inform intervention efforts.
