 The results of this study suggest that there has been an increase in the prevalence of depression and anxiety among Chinese social media users during the Covid-19 pandemic. Females are more likely to experience severe symptoms of both depression and anxiety compared to males. Additionally, the severity of depressive symptoms decreased with age and increased with unemployment, while the severity of anxiety symptoms decreased with higher education and improved resilience, but increased with more stress, feeling less adapted, and spending more time on Covid-19-related information. These findings highlight the importance of providing adequate support and resources to those who may be at risk of developing mental health issues due to the pandemic.
