Using dyadic analysis, this study examined whether emotion suppression is a valid mediator in the relationship between mood change following a stressful couple discussion and subsequent food intake among cohabiting couples. In a laboratory setting, 80 heterosexual couples were presented with a bogus taste test immediately after discussing aspects that they would like each other to change. Mood change, emotion suppression and appetite perceptions were self-reported using visual analogue scales, and BMI was calculated based on objective measures. The moderated-mediation Actor-Partner Interdependence Model revealed a significant indirect conditional effect, showing that mood worsening was significantly associated with higher emotion suppression and that emotion suppression was significantly associated with more food intake among spouses with a high BMI. For spouses with a low BMI, the reverse effect was found, i.e., mood worsening was significantly associated with less food intake through the indirect effect of emotion suppression. Furthermore, an indirect partner effect was observed regardless of BMI, i.e., mood worsening was related to more food intake, which was mediated by the partner's emotion suppression. These results highlight the key role of emotion suppression in the relationship between mood change and food intake in the context of a stressful couple discussion.
本研究采用对偶分析，考察了情绪抑制在夫妻讨论压力事件后情绪变化与随后共同居住的夫妻食物摄入之间的关系中是否是有效的中介因素。在实验室环境中，80 对异性夫妻在讨论完他们希望对方改变的方面后，立即接受了一项虚假的味觉测试。使用视觉模拟量表报告情绪变化、情绪抑制和食欲感知，根据客观测量计算 BMI。调节中介的 Actor-Partner 相互依赖模型显示出显著的间接条件效应，表明情绪恶化与更高的情绪抑制显著相关，而情绪抑制与 BMI 高的配偶的食物摄入显著相关。对于 BMI 低的配偶，发现了相反的效果，即情绪恶化通过情绪抑制的间接效应与更少的食物摄入显著相关。此外，无论 BMI 如何，都观察到间接的伴侣效应，即情绪恶化与更多的食物摄入有关，这是由伴侣的情绪抑制介导的。这些结果强调了在夫妻讨论的压力情境下，情绪抑制在情绪变化和食物摄入之间关系中的关键作用。
