本研究旨在新型冠状病毒(COVID-19)疫情蔓延之际，从社会心理学视角就心理弹性与心理障碍对COVID-19应激反应的干预作用及影响效应展开分析，以探寻能够缓解疫情应激行为的有效途径。鉴于此，通过网络调查平台在全国范围内开展调研工作，并对采集的1,248份有效数据进行处理。研究结果显示，心理弹性对心理障碍(焦虑及抑郁)能够起到显著的干预作用；抑郁显著负向影响于COVID-19应激反应的诸维度(认知评价、情绪恐慌、防御行为)，而焦虑仅对认知评价造成负向影响，与情绪恐慌及防御行为则呈正向作用关系；心理弹性能够显著增强对COVID-19的认知评价与防御行为，缓解对疫情的情绪恐慌，从而有效调适COVID-19应激反应。研究推断，心理弹性在严重突发性事件、心理障碍与应激反应之间，能够起到显著的缓冲及保护作用，以此可为COVID-19应激行为问题的应对策略提供借鉴依据.

The goal of this research is to examine COVID-19 stress from the perspective of social psychology and to explain the relationships between resilience, anxiety, depression and COVID-19 stress in order to contribute to overcoming the crisis of COVID-19 epidemic. Data collected from 1,248 Chinese men and women through a network survey questionnaire were analyzed to test the hypothesis. Results revealed a significant effect of resilience on anxiety and depression. Depression was negatively correlated with all sub-categories of COVID-19 stress, and anxiety had significant influences on COVID-19 stress statistically. Among the sub-categories of COVID-19 stress, cognitive evaluation and defense response was positively correlated with resilience, but panic was negatively correlated with resilience.
