INTRODUCTION Emotional eating is a mental health concern, common in adolescents, that develops as a result of their tendency to use high-energy food to regulate their fluctuating emotions. Due to their highly fluctuating emotional life, adolescents tend to have unique within-person profiles of emotional experiences that change across moments and days, often lost in global assessments of emotions. Hence, it is imperative to examine individual differences in dynamics of emotions, as experienced in daily life, in relation to emotional eating in adolescents. METHODS In an Ecological Momentary Assessment study, we examined individual differences in three within-person dynamic characteristics (baseline levels, intraindividual variability, and emodiversity) of emotions in 158 dominantly Hispanic adolescents in the United States, aged 14-17 years old, predicting trait-level emotional eating. RESULTS Results indicated that higher negative emodiversity, baselines, and variability in stress were predictive of emotional eating in adolescents. When all considered together, negative emodiversity (i.e., variety of the types of negative emotions experienced in one's daily life) remained the only significant predictor of emotional eating. CONCLUSIONS This study affirms the importance of diversity in emotional experiences in relation to emotional eating, particularly in daily contexts of adolescents' lives. Additionally, the study emphasizes the importance of distinguishing between diversity (i.e., variety in types) in positive versus negative emotional experiences with regard to emotional eating. By taking into account the ecological validity of adolescents' daily lives and individual differences in dynamical changes in emotions, we are taking a step forward by shedding light on how the dynamics of negative emotions-in terms of within-person baselines, variability, and diversity-might be related to general levels of emotional eating in adolescents.

负面情绪多样性与青少年情绪化饮食有关：对日常生活中情绪动态的检查。

引言 情绪化进食是一种心理健康问题，在青少年中很常见，这是由于他们倾向于使用高能量食物来调节情绪波动而发展起来的。由于他们的情感生活波动很大，青少年往往具有独特的个人情感体验概况，这些情感体验会随着时间和日子的变化而变化，往往会迷失在整体情感评估中。因此，必须检查日常生活中所经历的与青少年情绪化饮食相关的情绪动态的个体差异。方法 在一项生态瞬时评估研究中，我们检查了 158 名年龄在 14-17 岁的美国主要西班牙裔青少年的情绪的三个个体动态特征（基线水平、个体内变异性和情绪多样性）的个体差异，预测特质水平的情绪化饮食。结果 结果表明，较高的负面情绪多样性、基线和压力变异性可预测青少年情绪化进食。当综合考虑所有因素时，负面情绪多样性（即在日常生活中经历的负面情绪的种类繁多）仍然是情绪化进食的唯一重要预测因素。结论 本研究证实了与情绪化饮食相关的情绪体验多样性的重要性，尤其是在青少年生活的日常生活中。此外，该研究强调了在情绪化饮食方面区分积极和消极情绪体验的多样性（即类型的多样性）的重要性。通过考虑青少年的生态效度
