Resilience, pessimism, and depression in undergraduates in Hong Kong during Covid-19: A cross-sectional online survey study (Preprint)
BACKGROUND Adolescence and young adulthood is a period of heightened risk of mental disorders onset. The Covid-19 pandemic may have impacted the daily lives and learning of students, exposing them to risks of emotional distress. Understanding factors associated with individual differences in distress can inform remedial strategies for schools. OBJECTIVE To investigate the impact of Covid-19 on undergraduate students’ lifestyle and learning, and explore relationship between depressive symptoms, resilience, and optimism/pessimism bias in undergraduate students in Hong Kong. METHODS Cross-sectional online survey of undergraduate students in a university (n=1020) before and during the third wave of Covid-19 outbreak in Hong Kong between May and August 2020. Changes in habits and family conflicts, depressive symptoms (measured using Patient Health Questionnaire-9), resilience (measured using Connor-Davidson Resilience Scale), optimism/pessimism towards Covid-19 risks, and knowledge about Covid-19 were recorded. Multivariable linear regression and mediation analyses were used to explore relationships with depressive symptoms. RESULTS 61.7% of respondents have mild to severe depressive symptoms. The regression model found that 18.5% of the variance in depressive symptoms was explained by resilience, pessimism bias, changes in sleep, decrease in study at home, and increase in family conflict. Mediation analysis showed that resilience is indirectly related to depressive symptoms through its relationship with pessimism (ab = -0.042, CI = -0.057 to -0.013). Higher resilience was associated with lower depressive symptoms even after accounting for resilience’s indirect effect through pessimism (c’ = 0.311, P < .001). CONCLUSIONS The findings highlight the mental health vulnerability of undergraduate students. Measures to reduce family conflict, maintain healthy daily habits, adjust optimism/pessimism bias, and enhance resilience may be useful for improving the mental wellbeing of undergraduate students during the pandemic.
