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.
情绪性进食与体重增加和减肥干预期间减肥困难有关。理论和实证工作表明，无聊可能是问题性进食行为的一个重要预测因子。然而，很少有研究探讨无聊在情绪性进食中的作用。此外，个体识别内部线索（即内感受）的能力差异可能会改变无聊对情绪性进食的影响。本研究假设，在考虑到消极和积极情绪后，易无聊倾向会预测情绪性进食的独特差异，并且易无聊倾向与情绪性进食之间的关联在内感受能力较差的个体中比内感受能力较好的个体中更强。假设在两个大型样本中使用多元线性回归进行检验。从 MTurk（n=365；59.2%女性）和本科研究小组（n=461；52.9%女性）招募了年龄在 18-65 岁的参与者。参与者完成了自我报告的测量：无聊倾向量表；荷兰饮食行为问卷-情绪性进食；多维内感受意识评估-2；直觉饮食量表-2-对饥饿和饱腹感线索的依赖；以及积极和消极情绪量表。即使考虑到消极和积极情绪的广泛维度，易无聊倾向在两个样本中都是情绪性进食的一个重要预测因子（ps<0.001）。内感受在两个样本中都没有调节易无聊倾向和情绪性进食之间的关联（ps>0.05），但它是情绪性进食的一个独立预测因子（ps<0.001）。易无聊倾向和内感受能力可能需要作为情绪性进食预防和治疗的目标。未来的研究应该继续探索不同的情绪类别和情绪性进食中的内感受不同方面，并研究可以为干预努力提供信息的新机制。
