ABSTRACT Self-concept clarity reflects how confidently and clearly an individual defines the self-belief, and it is theorized to help individuals to be more resilient in the face of stressors. The present study aimed at investigating how self-concept clarity may be implicated in the stress process related to the COVID-19 outbreak, by examining its association with daily negative affect, as a short-term adaptational outcome. The impact of the total number of positive cases, as an objective index of COVID-19 spreading, on negative affect was also tested. Participants were 287 young Italian adults (52% female; Mage = 22.68 years, SDage = 2.62), who completed twelve daily diaries (of which five after the lockdown measure was introduced). Results from multilevel growth modeling showed that individuals low in self-concept clarity reported the highest levels of negative affect across the study period, compared to individuals high in self-concept clarity. Moreover, after the issuing of the lockdown measure, individuals high in self-concept clarity showed a steeper increase in their daily level of negative affect, compared to individuals low in self-concept clarity, indicating their responsiveness to the new situation. The total number of new cases was not related to daily negative affect. These findings attest the protective role of self-concept clarity and its impact on emotional responding to the lockdown measure in Italy.

自我概念清晰可以预防大流行吗？COVID-19 爆发期间自我概念清晰度和负面影响的日常研究

摘要 自我概念的清晰度反映了个人对自我信念的定义有多自信和清晰，理论上可以帮助个人在面对压力时更有弹性。本研究旨在通过检查自我概念清晰度与日常负面影响的关联，将其作为短期适应结果，来调查自我概念清晰度如何与 COVID-19 爆发相关的压力过程有关。还测试了阳性病例总数作为 COVID-19 传播的客观指标对负面影响的影响。参与者是 287 名意大利年轻人（52% 为女性；法师 = 22.68 岁，SDage = 2.62），他们完成了 12 份每日日记（其中 5 份是在实施封锁措施后）。多层次成长模型的结果表明，与自我概念清晰度高的个体相比，自我概念清晰度低的个体在整个研究期间报告的负面影响水平最高。此外，在锁定措施发布后，自我概念清晰度高的人与自我概念清晰度低的人相比，其日常负面情绪水平的增加幅度更大，表明他们对新情况的反应能力强。新病例总数与每日负面影响无关。这些发现证明了自我概念清晰度的保护作用及其对意大利封锁措施的情绪反应的影响。与自我概念清晰度低的人相比，自我概念清晰度高的人在日常负面情绪水平上的增加幅度更大，表明他们对新情况的反应能力强。新病例总数与每日负面影响无关。这些发现证明了自我概念清晰度的保护作用及其对意大利封锁措施的情绪反应的影响。与自我概念清晰度低的人相比，自我概念清晰度高的人在日常负面情绪水平上的增加幅度更大，表明他们对新情况的反应能力强。新病例总数与每日负面影响无关。这些发现证明了自我概念清晰度的保护作用及其对意大利封锁措施的情绪反应的影响。
