Purpose: Shanghai, a mega-city with a population of 25 million, was becoming the first city in mainland China to erupt in the Omicron pandemic. The pandemic and the quarantine measures of whole city static management brought out big challenges for the population. This study sought to examine the psychological impact of such quarantine measures.
Methods: A cross-sectional study was conducted in China between April 8 to April 14, 2022. The survey contained inventories of stress perception, emotion states, duration of quarantine, and demographic characteristics. A total of 1,051 participants in Shanghai who were quarantined at home were included by random sampling.
Results: We found moderate-to-mild perceived stress (3.248± 1.936) and emotion states (3.453± 2.094). Individuals with high negative emotions had high levels of perceived stress. Specifically, the population aged 30– 49, female, with higher household income, staying with the elderly or children, were more likely to report high stress and negative emotion. Hierarchical regression and the further path analysis indicated that emotion states partially mediated the relationship between quarantined days at home and perceived stress.
Conclusion: There was a moderate-to-mild level of perceived stress and emotion when quarantined at home for an average of 20 days in Shanghai. The present findings implicated more positive emotion then less stress perception at the same duration of quarantine. It was suggested to consider the measures taken to construct positive emotions for the public to overcome negativity and bring out a virtuous circle to thrive, if the quarantine has to be continued for preventing the pandemic.
