ABSTRACT: Background: During the coronavirus disease 2019 (COVID-19) pandemic, quarantine as an effective public health measure has been widely used in China and elsewhere to slow down the spread, while high-risk psychological response populations remain under-reported. Objective: The aim of the study is to investigate the depressive and anxiety symptoms among the high-risk individuals quarantined during the COVID-19 pandemic in China. Methods: An online survey was conducted from February 29 to April 10, 2020, among individuals quarantined for at least 2 weeks due to the high-risk exposure. Chinese versions of the nine-item Patient Health Questionnaire (PHQ-9) with a seven-item Generalized Anxiety Disorder (GAD-7) were applied to assess depressive and anxiety symptoms, respectively. Compliance with quarantine and knowledge of COVID-19 was also assessed. An unconditional logistic regression model was performed to identify the correlators. Results: Of the 1,260 participants completing the full survey, 14.0% (95% CI: 12.2-16.1%), 7.1% (95% CI: 5.9-8.7%), and 6.3% (95% CI: 5.1-7.8%) had at least moderate symptoms of depression, anxiety, and a combination of depression and anxiety (CDA), respectively; 14.8% (95% CI: 13.0-16.9%) had at least one condition. Multivariate analysis showed that participants with an undergraduate or above degree were more likely to report depressive (OR = 2.98, 95% CI: 1.56-5.72) and anxiety symptoms (OR = 2.95, 95% CI: 1.14-7.63) than those with middle school education. Those who were unemployed (OR = 0.37, 95% CI: 0.21-0.65 for depression; OR = 0.31, 95% CI: 0.14-0.73 for anxiety), students (OR = 0.14, 95% CI: 0.04-0.48 for depression; OR = 0.11, 95% CI: 0.01-0.85 for anxiety), and more knowledgeable of COVID-19 (OR = 0.84, 95% CI: 0.73-0.96 for depression, OR = 0.82, 95% CI: 0.68-0.98 for anxiety) were less likely to report depressive and anxiety symptoms. Higher quarantine compliance correlated with lower risks of depressive (OR = 0.94, 95% CI: 0.91-0.96) and anxiety symptoms (OR = 0.95, 95% CI: 0.91-0.98). Conclusion: Individuals under quarantine during the COVID-19 pandemic suffered prevalent depressive and anxiety symptoms. Consequently, comprehensive interventional measures, including knowledge dissemination, timely virus tests, and strengthened communication, may minimize quarantine's adverse effects.
