There is ample evidence linking broad trait emotion regulation deficits and negative affect with loss-of-control (LOC)-eating among individuals with obesity and binge eating, however, few studies have examined emotion regulation at the state-level. Within and across day fluctuations in the ability to modulate emotion (or regulate emotional and behavioral responses), one facet of state emotion regulation, may be a more robust momentary predictor of LOC-eating than momentary negative affect and trait emotion regulation ability. As such, the current study tested if daily emotion modulation, and daily variability in emotion modulation differed on days with and without LOC-eating episodes, and if momentary emotion modulation was associated with subsequent LOC-eating episodes. For two weeks individuals (N=14) with obesity and binge eating completed surveys as part of an ecological momentary assessment study. Participants reported on current ability to modulate emotion, LOC-eating, and current negative affect. On LOC-eating days compared to non-LOC-eating days, ability to modulate emotion was poorer (ß =0.10, p<.001) and average variability in ability to modulation emotions was greater (ß=0.56, p=.008), even when controlling for negative affect. Greater momentary difficulty modulating emotion was associated with a 40% increase in subsequent risk for LOC-eating (ß=0.34, p=.071, OR=1.40). Findings from this pilot study suggest that individuals with LOC-eating report poorer ability to modulate emotion and greater variability in ability to modulate emotion on LOC-eating days, even when controlling for negative affect. Future research should replicate findings and further elucidate the relationships between state emotion regulation, negative affect, and LOC-eating.

有充分的证据表明，在肥胖和暴饮暴食的个体中，广泛的情绪调节缺陷和负面影响与饮食失控（LOC）有关，然而，很少有研究在州一级检查情绪调节。调节情绪（或调节情绪和行为反应）的能力（或调节情绪和行为反应）的日内和跨日波动是状态情绪调节的一个方面，可能比暂时的负面影响和特质更能预测 LOC 饮食情绪调节能力。因此，目前的研究测试了每日情绪调节和情绪调节的每日变异性在有和没有 LOC 进食事件的日子里是否不同，以及瞬时情绪调节是否与随后的 LOC 进食事件有关。作为生态瞬时评估研究的一部分，肥胖和暴饮暴食的个体（ N = 14）在两周内完成了调查。参与者报告了当前调节情绪、LOC 饮食和当前负面影响的能力。与不吃 LOC 的日子相比，在吃 LOC 的日子里，调节情绪的能力较差（ß =0.10，p <.001），调节情绪的能力的平均变异性更大（ß=0.56 ，p=.008），即使在控制负面影响时也是如此。更大的暂时性情绪调节困难与随后的 LOC 进食风险增加 40% 相关（ß=0.34 ，p =.071，OR=1.40）。这项初步研究的结果表明，即使在控制负面影响的情况下，食用 LOC 的个体报告调节情绪的能力较差，并且在食用 LOC 的日子调节情绪的能力变化更大。未来的研究应该重复研究结果并进一步阐明状态情绪调节、负面影响和 LOC 饮食之间的关系。
