Depressive Symptoms and Its Correlates in Undergraduates during the COVID-19 Pandemic.

Introduction: This study aims to investigate depressive symptoms and its association with resilience, pessimistic bias of COVID-19, lifestyle changes, and family conflicts among undergraduates in a Hong Kong university.

Methods: 1020 undergraduates in The University of Hong Kong completed the online survey between May and August 2020. Severity of depressive symptoms was assessed using the Patient Health Questionnaire-9. Resilience was assessed using the Connor-Davidson Resilience Scale. Pessimistic bias was assessed using two questions on the perceived risks of contracting COVID-19 and of dying from COVID-19. Changes in lifestyles and the presence of family conflicts were measured. Multivariable and mediation analyses were performed to examine association of depressive symptoms with other variables.

Results: 61.7% of the respondents reported having mild to severe depressive symptoms. 18.5% of the variance in depressive symptoms was explained by resilience, pessimistic bias, changes in the frequency of sleep, studying at home, and family conflict. Pessimistic bias partially mediated the association between resilience and depressive symptoms.

Conclusion: The proportion of undergraduates with mild to severe depressive symptoms during the pandemic was high. Measures to reduce family conflict, maintain healthy daily habits, adjust pessimistic bias, and enhance resilience may help to improve the mental well-being of undergraduates during the pandemic.
