The purpose of the present study was to propose and test two models to understand the relationship between perceived vulnerability to COVID-19 (PVC) and COVID-19-related traumatic stress (TS), as well as the variables that may mediate and moderate this relationship among individuals who have not yet been infected with COVID-19. Using an online survey, data were collected between late March and early April 2020. Participants were recruited through Amazon Mechanical Turk and included 747 adults living in the United States. Supporting our hypotheses, results indicated that both COVID-19-related worries and social isolation were significant mediators of the relationship between PVC and TS (Model 1). In addition, the results of a moderated mediation analysis indicated that the indirect effect of PVC on TS through COVID-19-related worries was stronger for participants who reported greater social isolation (Model 2). Although future research is needed, these findings suggest that both social isolation and disease-related worries may be important variables that can be targeted in interventions to reduce pandemic-related TS.
本研究旨在提出并检验两个模型，以理解感知 COVID-19 易感性（PVC）与 COVID-19 相关创伤性应激（TS）之间的关系，以及在尚未感染 COVID-19 的个体中，可能调节和中介这种关系的变量。我们使用在线调查于 2020 年 3 月下旬至 4 月初收集数据。参与者是通过亚马逊 Mechanical Turk 招募的，包括 747 名居住在美国的成年人。研究结果支持了我们的假设，表明 COVID-19 相关担忧和社会隔离都是 PVC 和 TS 之间关系的重要中介变量（模型 1）。此外，调节中介分析的结果表明，对于报告社会隔离程度较高的参与者，PVC 通过 COVID-19 相关担忧对 TS 的间接影响更强（模型 2）。尽管需要进一步的研究，但这些发现表明，社会隔离和与疾病相关的担忧可能是干预措施中可以针对的重要变量，以减轻与大流行相关的 TS。
