Associations Between the Perceived Severity of the COVID-19 Pandemic, Cyberchondria, Depression, Anxiety, Stress, and Lockdown Experience: Cross-sectional Survey Study (Preprint)
BACKGROUND The outbreak of the COVID-19 pandemic has caused great panic among the public, with many people suffering from adverse stress reactions. To control the spread of the pandemic, governments in many countries have imposed lockdown policies. In this unique pandemic context, people could obtain information on the pandemic dynamics over time on the Internet. However, searching for health-related information from the Internet frequently will increase public’s possibility of being troubled by online information and experiencing symptoms of cyberchondria. OBJECTIVE This study aimed to examine the relationships between people’s perceived severity of the COVID-19 pandemic (PSCP) and their depression, anxiety, and stress and to explore the role of cyberchondria, which is closely related to the Internet, in these relationship mechanisms. In addition, we also examine the moderating role of lockdown experience. METHODS In February 2020, a total of 486 participants were recruited from pandemic areas in China via an online platform. We used questionnaires to measure participants’ PSCP, the severity of cyberchondria, depression, anxiety, and stress symptoms, and lockdown experience. SPSS 24.0 software was used to test for common method bias and perform the descriptive statistical analysis and correlation analysis Moderated mediation models were examined using SPSS PROCESS Version 3.5 software. RESULTS The results showed a positive association between PSCP and depression(β = 0.36, t = 8.51, p < 0.001), anxiety(β = 0.41, t = 9.84, p < 0.001), and stress(β = 0.46, t = 11.45, p < 0.001), which were mediated by cyberchondria(β = 0.36, t = 8.59, p < 0.001). The direct effects of PSCP on anxiety(β = 0.07, t = 2.01, p = 0.045) and stress(β = 0.09, t = 2.75, p = 0.006) and the indirect effects of cyberchondria on depression(β = 0.10, t = 2.59, p = 0.009) and anxiety(β = 0.10, t = 2.50, p = 0.01) were moderated by lockdown experience. CONCLUSIONS The higher individuals’ PSCP, the more serious the symptoms of depression, anxiety, and stress, and the associations were partially mediated by cyberchondria, Individuals with higher PSCP were more likely to develop cyberchondria, which aggravates individuals’ depression, anxiety and stress symptoms. Negative lockdown experience exacerbated the impact of the COVID-19 pandemic on mental health.
