There is little research examining how individuals’ daily experience during a pandemic affects their daily mental health status and work performance. To address this knowledge gap, we invoke conservation of resources theory to propose a resource-based framework explaining how individuals’ daily COVID-19 intrusive experience affects their daily mental health status (depression and anxiety) and work performance via its effect on daily psychosocial resource loss and gain; We further examine whether their supervisors’ daily visionary leadership behaviour alleviates the adverse impacts of daily COVID-19 intrusive experience. Results, based on daily diary data from 139 football players (or soccer players) at 15 professional football clubs over 5 days during the COVID-19 pandemic, provided support for our predictions. Our study extends the literature by providing previously undocumented evidence on daily within-person variations in mental health status and work performance during a pandemic and by offering theory-driven insights into the mediating and moderating mechanisms involved in within-person variations.

在 COVID-19 大流行下钻探：职业足球运动员心理健康和锻炼表现的日记研究

很少有研究调查个人在大流行期间的日常经历如何影响他们的日常心理健康状况和工作表现。为了解决这一知识差距，我们援引资源保护理论提出了一个基于资源的框架，解释个人的日常 COVID-19 侵入性经历如何通过其对日常心理社会资源的影响来影响他们的日常心理健康状况（抑郁和焦虑）和工作绩效损失和收益；我们进一步研究了他们的主管日常有远见的领导行为是否减轻了日常 COVID-19 侵入性体验的不利影响。结果基于在 COVID-19 大流行期间 5 天内来自 15 个职业足球俱乐部的 139 名足球运动员（或足球运动员）的每日日记数据，为我们的预测提供了支持。
