The COVID-19 pandemic precipitated an uptick in poor mental health outcomes, including coronavirus-related anxiety and distress. Preliminary research has shown that intolerance of uncertainty (IU) and worry proneness, two transdiagnostic risk factors for anxiety and related disorders, are associated cross-sectionally with pandemic-related fear and distress. However, the extent to which IU and worry proneness prospectively predict coronavirus-related anxiety and distress is unclear. Whether IU and worry may also interact in prospectively predicting coronavirus-related anxiety and distress is also unknown. To address this knowledge gap, the present study examined IU and trait worry as prospective predictors of the level and trajectory of coronavirus anxiety and COVID stress syndrome over time, as well as the extent to which worry moderated the relation between IU and pandemic-related outcomes. Participants (n = 310) who completed self-report measures of IU and trait worry in 2016 were contacted following the onset of COVID-19 in 2020 and completed biweekly measures of coronavirus anxiety and COVID stress syndrome for 30 weeks. Multilevel models revealed that IU assessed in 2016 significantly predicted the severity of both coronavirus anxiety and COVID stress syndrome throughout the study period in 2020. Worry also moderated the link between IU and coronavirus anxiety, such that individuals with high levels of trait worry and high IU in 2016 experienced the most coronavirus anxiety in 2020. Results suggest that IU and worry functioned as independent and interactive vulnerability factors for subsequent adverse psychological reactions to COVID-19. Clinical implications and future directions are discussed.
标题：不确定性容忍度和特质性担忧在预测新冠相关焦虑和压力中的作用：一项前瞻性研究
摘要：新冠疫情大流行导致心理健康状况恶化，包括与新冠病毒相关的焦虑和困扰。初步研究表明，不确定性容忍度（IU）和担忧易感性，这两个焦虑和相关障碍的跨诊断风险因素，与大流行相关的恐惧和困扰存在横断面关联。然而，IU 和担忧易感性是否能前瞻性地预测新冠相关焦虑和压力还不清楚。IU 和担忧是否也能前瞻性地预测新冠相关焦虑和压力之间的相互作用也尚不清楚。为了填补这一知识空白，本研究考察了 IU 和特质性担忧作为前瞻性预测因素，预测了随着时间的推移，新冠相关焦虑和 COVID 应激综合征的水平和轨迹，以及担忧在多大程度上调节了 IU 与大流行相关结果之间的关系。2016 年完成 IU 和特质性担忧自我报告测量的参与者，在 2020 年新冠疫情爆发后被联系，并在 30 周内每两周完成一次新冠相关焦虑和 COVID 应激综合征的测量。多层次模型显示，2016 年评估的 IU 显著预测了 2020 年整个研究期间新冠相关焦虑和 COVID 应激综合征的严重程度。担忧也调节了 IU 和新冠相关焦虑之间的联系，即 2016 年特质性担忧和 IU 水平较高的个体在 2020 年经历了最严重的新冠相关焦虑。结果表明，IU 和担忧是对 COVID-19 产生后续不良心理反应的独立和交互脆弱性因素。讨论了临床意义和未来方向。
