COVID-19 perseverative cognition and depressive symptoms in Hong Kong: The moderating role of resilience, loneliness and coping strategies.

BACKGROUND: The COVID-19 pandemic significantly increased depression prevalence in general population. However, the relationship between persistent dysfunctional thinking associated with COVID-19 (perseverative-cognition) and depression, and its potential moderators are understudied. We aimed to examine the association between COVID-19 perseverative-cognition and depression, and the moderating effect of potential risk and protective factors on this association in general public during the peak of fifth COVID-19 wave in Hong Kong. METHODS: This survey recruited 14,269 community-dwelling adults between March 15-April 3, 2022 to investigate association between COVID-19 perseverative-cognition and depression, and the moderating effect of resilience, loneliness and three coping strategies (including emotion-focused, problem-focused and avoidant coping) on this association, using hierarchical regression models and simple slope analyses. COVID-19 perseverative cognition was assessed by the Obsession with COVID-19 Scale (OCS) and depressive symptoms were measured by the Patient Health Questionnaire-9 (PHQ-9). RESULTS: Perseverative-cognition was positively associated with depression severity. Resilience, loneliness and three coping strategies moderated the association between perseverative-cognition and depression. Specifically, greater resilience and emotion-focused coping ameliorated the association between perseverative-cognition and depression, while higher levels of loneliness, avoidant and problem-focused coping accentuated such association. LIMITATIONS: Cross-sectional design precluded establishing causality among variables. CONCLUSION: This study affirms that COVID-19 perseverative-cognition is significantly related to depression. Our findings indicate the potential critical role of enhanced personal resilience and social support, and adoption of emotion-focused coping in mitigating negative effect of COVID-19 related maladaptive thinking on depression severity, thereby facilitating development of targeted strategies to reduce psychological distress amidst the prolonged pandemic.

The Hong Kong youth epidemiological study of mental health (HK-YES)-A population-based psychiatric epidemiology study of youth mental health in Hong Kong: A study protocol.

AIM: Young people in Hong Kong have been facing numerous population-level events over the past year, including social unrest and the COVID-19 pandemic. Representative data concerning the mental health of youths, however, is limited. The Hong Kong Youth Epidemiological Study of Mental Health (HK-YES) is commissioned to provide the first representative prevalence estimates and correlates of mental disorders among young people in Hong Kong. It will also examine the help-seeking behaviours, treatment rates, quality of life, and functional outcomes of the young people. More importantly, the direct and indirect economic costs of mental disorders in youths will be estimated. METHODS: A total of 4500 community-dwelling participants aged 15-24 years from Hong Kong will be surveyed. Participants will be selected using a multistage stratified sampling design to provide representative estimates of the youth population in Hong Kong. All interviews will be conducted using computer-assisted personal interviewing methods for assessments covering areas of psychiatric diagnoses, symptomatology, functioning, quality of life, disability, service utilization, health economic costs of mental disorders, and sociodemographic and lifestyle characteristics. A population-weighted prevalence will be estimated using survey weights. Methods such as multivariate logistic and linear regression analyses will be used to calculate the risks and odds of factors that might be associated with different mental disorders. CONCLUSION: As the first population-based youth study in Hong Kong, HK-YES collects extensive and representative data on different mental conditions and their associated factors among young people. The information gathered will be important for future planning on youth mental health services in Hong Kong and will offer the opportunity for a more meaningful comparison of data with other youth populations.
