سرکوب احساسات و مصرف غذا در چارچوب یک بحث چندگانه: تجزیه و تحلیل دیودیک

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.
