Anxiety and depression in the post-pandemic era: concerns about viral mutation and re-outbreak

The 2020 coronavirus pandemic (COVID-19) has been raging for more than 20 months, putting significant strain on public health systems around the world. Despite the fact that the pandemic has been effectively managed in certain countries, regional outbreaks and viral mutations continue to pose a threat to people's lives. The likelihood of post-pandemic changes in people's psychological situations warrants more investigation.

This study was conducted in the context of another outbreak in Zhangjiajie, China, respondents (infected patients, healthy population) were required to complete self-administered questions and standardized questionnaires, including the patient health questionnaire-9 (PHQ-9), the generalized anxiety disorder-7 (GAD-7), and the Brief Illness Perception Questionnaire (BIPQ).

We conducted an anonymous questionnaire survey of infected patients (excluding critically ill patients) in the confirmed COVID-19 ward of Zhangjiajie City People's Hospital's East Hospital from August 14 to 24, 2021, and used convenience sampling to survey medical staff and the general public to assess the psychological reactions of different populations during the delta variant outbreak pandemic. Differences in anxiety and depression severity were compared between groups, with logistic regression models constructed to explore potential factors associated with scoring clinical significant levels of depression and/or anxiety.

There is no significant difference (p value = 0.228) between anxiety and depression in patients (n = 53), general public (n = 97), medical personnel (n = 103), and support workers (n = 65). Females reported higher scores on the GAD-7 and the BIPQ, reduced communication with family and friends appeared to be a risk factor for clinically significant anxiety and depression.

There were no significant differences in anxiety and depression across populations explored in this study, but females had higher anxiety and illness perception than males, and effective communication may help improve mental health.
