Abstract

Background and objectives: COVID Stress Syndrome (CSS) is a new type of health anxiety triggered by the COVID epidemic. However, we know little about the causal relationship with CSS symptoms and the temporal and dynamic interactions between symptoms and cognitive processes associated with health anxiety.

Design: During the epidemic of COVID-19, 193 Chinese university students completed experience sampling methods on CSS symptoms and related constructs of health anxiety three times a day for 14 days.

Methods: Multilevel vector autoregressive (mlVAR) models were used to estimate contemporaneous and temporal networks at the within-person level.

Results: (1) The CSS symptoms were divided into two periods of growth and maintenance during these 14 days. (2) The COVID-19 traumatic stress dimension played a crucial role in maintaining the symptom network. (3) Catastrophizing of bodily sensations and rumination formed a positive feedback loop with COVID traumatic stress symptoms dimension of the CSS.

Conclusion: This study advances the current understanding of CSS at the symptom level and temporal dynamics. The results suggest that the COVID traumatic stress dimension is a core mechanism for CSS maintenance and could be a point of focus for intervention and treatment in clinical practice.

COVID - 19应激综合征症状网络维持机制：动态网络分析

背景与目的：新冠肺炎应激综合征（CSS）是新冠肺炎疫情引发的一种新型健康焦虑。然而，我们对CSS症状的因果关系以及与健康焦虑相关的症状和认知过程之间的时间和动态相互作用知之甚少。设计：在2019冠状病毒病流行期间，193名中国大学生每天3次，连续14天完成CSS症状及健康焦虑相关构式的体验抽样方法。方法：使用多水平向量自回归（mlVAR）模型来估计人体内水平的同期和时间网络。结果：(1)14 d内CSS症状分为生长和维持两个阶段。(2)新冠肺炎创伤应激维度对症状网络的维持起着至关重要的作用。(3)身体感觉的灾难化和反刍与CSS的COVID创伤应激症状维度形成正反馈回路。结论：本研究在症状水平和时间动态方面提高了对CSS的现有认识。结果提示，COVID创伤应激维度是CSS维持的核心机制，可作为临床干预和治疗的重点。

期刊介绍： This journal provides a forum for scientific, theoretically important, and clinically significant research reports and conceptual contributions. It deals with experimental and field studies on anxiety dimensions and stress and coping processes, but also with related topics such as the antecedents and consequences of stress and emotion. We also encourage submissions contributing to the understanding of the relationship between psychological and physiological processes, specific for stress and anxiety. Manuscripts should report novel findings that are of interest to an international readership. While the journal is open to a diversity of articles.
