This study is aimed to investigate the status of general anxiety and depression among suspected patients of COVID-19 and explore whether psychological flexibility can serve as a mediator between perceived stress and general anxiety or depression. Total of 180 participants completed the online questionnaire which comprised demographic information, the Perceived Stress Scale (PSS), the 7-item Generalized Anxiety Disorder scale (GAD-7), the 9-item Patients Health Questionnaire (PHQ-9), the Acceptance and Action Questionnaire-II (AAQ-II) and the Cognitive Fusion Questionnaire (CFQ). Statistical methods including correlation analysis, multiple linear regression analysis and structural equation model were used in this study. The scores of 23.9% (43/180) and 34.4% (62/180) of participants were higher than the cut points of GAD-7 and PHQ-9 respectively. Psychological flexibility was significantly correlated with perceived stress, general anxiety and depression. Multiple regression analyses showed the possible mediation effect of psychological flexibility between perceived stress and general anxiety or depression. The structural equation model confirmed that psychological flexibility partially mediated between perceived stress and general anxiety or depression. Our findings suggested the potential benefit of Acceptance and Commitment Therapy (ACT) as a psychological support approach in suspected patients of COVID-19 because ACT targets psychological flexibility.

本研究旨在调查 COVID-19 疑似患者的普遍焦虑和抑郁状况，并探讨心理灵活性是否可以作为感知压力与普遍焦虑或抑郁之间的中介。共有 180 名参与者完成了在线问卷，其中包括人口统计信息、感知压力量表 (PSS)、7 项广泛性焦虑症量表 (GAD-7)、9 项患者健康问卷 (PHQ-9)、接受度行动问卷-II (AAQ-II) 和认知融合问卷 (CFQ)。本研究采用相关分析、多元线性回归分析和结构方程模型等统计方法。分别有23.9%（43/180）和34.4%（62/180）的参与者得分高于GAD-7和PHQ-9的分界点。心理灵活性与感知压力、普遍焦虑和抑郁显着相关。多元回归分析表明，心理灵活性在感知压力和一般焦虑或抑郁之间可能存在中介作用。结构方程模型证实，心理灵活性在感知压力和一般焦虑或抑郁之间起到部分中介作用。我们的研究结果表明，接受和承诺疗法 (ACT) 作为 COVID-19 疑似患者的心理支持方法具有潜在益处，因为 ACT 的目标是心理灵活性。多元回归分析表明，心理灵活性在感知压力和一般焦虑或抑郁之间可能存在中介作用。结构方程模型证实，心理灵活性在感知压力和一般焦虑或抑郁之间起到部分中介作用。我们的研究结果表明，接受和承诺疗法 (ACT) 作为 COVID-19 疑似患者的心理支持方法具有潜在益处，因为 ACT 的目标是心理灵活性。多元回归分析表明，心理灵活性在感知压力和一般焦虑或抑郁之间可能存在中介作用。结构方程模型证实，心理灵活性在感知压力和一般焦虑或抑郁之间起到部分中介作用。我们的研究结果表明，接受和承诺疗法 (ACT) 作为 COVID-19 疑似患者的心理支持方法具有潜在益处，因为 ACT 的目标是心理灵活性。
