During the COVID-19 pandemic, quarantine has been implemented as a physical distancing measure to reduce the risk of transmission. However, no studies have examined the relationship between quarantine and daily affective experiences. Few studies have examined the individual-level factors that may alleviate or strengthen the negative impact of quarantine on daily affective experiences. To this end, we conducted a diary study by comparing the affective experiences of people in quarantine with those of people not subject to quarantine. There were 201 participants in the study. After the pretest collecting responses on demographic information and entity theory of emotion, the participants completed a daily questionnaire measuring their daily positive and negative affect for 14 consecutive days. The results of hierarchical linear modeling showed that the participants in the quarantine condition reported less daily positive affect than those in the social interaction condition. We found that when the participants under quarantine believed more strongly that their emotions could not be changed, they reported a higher level of daily negative affect. These findings demonstrate the role of entity theory of emotion in understanding daily negative affect during quarantine.

情绪的实体理论与隔离期间更多的日常负面影响相关：来自健康年轻人的 14 天日记研究的证据。

在 COVID-19 大流行期间，隔离已作为一种物理疏远措施实施，以降低传播风险。然而，还没有研究检验隔离与日常情感体验之间的关系。很少有研究考察可能减轻或加强隔离对日常情感体验的负面影响的个人层面因素。为此，我们通过比较隔离人员和未隔离人员的情感体验，进行了一项日记研究。该研究共有 201 名参与者。在预测试收集人口统计信息和情感实体理论的回答后，参与者完成了一份每日问卷，测量他们连续 14 天的日常积极和消极影响。分层线性模型的结果表明，隔离条件下的参与者比社交互动条件下的参与者报告的日常积极影响要少。我们发现，当被隔离的参与者更加坚信他们的情绪无法改变时，他们报告的日常负面情绪水平更高。这些发现证明了情绪实体论在理解隔离期间日常负面影响方面的作用。
