情绪化饮食被定义为负面情绪后饮食的增加。自我报告的情绪化饮食与身体健康问题有关。然而，实验和日常日记研究表明，诱导或自然经历的负面情绪不会可靠地导致没有饮食失调的人增加饮食行为，即使是在自称情绪化饮食者中。情绪化进食可能取决于人们在特定情绪和进食之间建立的联系。我们描述了一组研究，其总体目标是确定考虑人们在饮食和不同离散情绪之间的关联变化是否是观察情绪化饮食的关键。在研究1（N = 118）和2（N = 111）中，我们要求人们报告他们在悲伤和焦虑之后吃东西的倾向，并确定他们在实验室（研究1）或日常生活中经历这些情绪时吃了多少。我们在这两项研究中都没有发现支持我们假设的证据;自称悲伤或焦虑的进食者在实验室中被诱导体验这些情绪时，或者在日常生活中体验这些情绪时，并没有吃得更多。因此，解释人们在进食与悲伤和焦虑这两种离散情绪之间的关联变化，并不是在实验室或日常生活中观察悲伤或焦虑进食行为的关键。预注册、材料、数据和代码：https://osf.io/kcqej/（研究1）和https://osf.io/3euvg/（研究2）。
Emotional eating is defined as an increase in eating following negative emotion. Self-reported emotional eating has been associated with physical health concerns. However, experimental and daily diary studies indicate that induced or naturally experienced negative emotions do not reliably lead to increased eating behavior in people without eating disorders, not even among self-professed emotional eaters. Emotional eating may depend on associations people have made between specific emotions and eating. We describe a set of studies with the overarching goal of determining whether accounting for the variation in people's associations between eating and different discrete emotions is the key to observing emotional eating. In both Study 1 (N = 118) and 2 (N = 111), we asked people to report on their tendency to eat following sadness and anxiety and determined how much they ate when induced to feel sad or anxious in the lab (Study 1) or experiencing these emotions in daily life (Study 2). We found no support for our hypotheses in either study; self-professed sad- or anxious-eaters did not eat more when induced to experience these emotions in the lab, or when experiencing these emotions in daily life. Thus, accounting for the variation in people's associations between eating and two discrete emotions, sadness and anxiety, is not the key to observing sad or anxious eating behavior in the lab or in daily life.
