The Role of Insomnia and Exercise in COVID-19 Worries for Psychological Distress in Hong Kong Chinese: A Moderated Mediation Model.
Objective: To examine the role of insomnia as a mediator between worrying and mental health and whether the association between worrying and insomnia is moderated by the levels of exercise frequency.
Methods: A cross-sectional online survey was conducted during the fourth wave of the COVID-19 outbreak in Hong Kong (n = 988). Participants' insomnia, psychological distress, and exercise frequency were evaluated. A mediation analysis was performed to examine the direct effect of COVID-19 worries and their indirect effect through insomnia on psychological distress.
Results: A significant indirect effect of COVID-19 worries through insomnia was found on psychological distress (beta = 0.18, SE = 0.02, 95% CI = 0.14-0.22, p < .001). The significant index of moderated mediation supported the moderating effect of exercise frequency on the indirect effect of COVID-19 worries on psychological distress (IMM = 0.06, SE = 0.02, 95% CI = 0.02-0.10, p = .006). The conditional indirect effects of insomnia on psychological distress were significant in individuals with mean and higher exercise frequency but not in those with lower exercise frequency.
Conclusion: COVID-19 worries increased psychological distress through the worsening of sleep, and such an array of COVID-19 worries on insomnia was moderated by exercise frequency. Engaging more frequent exercise could reduce insomnia in people with less COVID-19 worries.
期刊介绍：
Behavioral Sleep Medicine addresses behavioral dimensions of normal and abnormal sleep mechanisms and the prevention, assessment, and treatment of sleep disorders and associated behavioral and emotional problems. Standards for interventions acceptable to this journal are guided by established principles of behavior change. Intending to serve as the intellectual home for the application of behavioral/cognitive science to the study of normal and disordered sleep, the journal paints a broad stroke across the behavioral sleep medicine landscape. Its content includes scholarly investigation of such areas as normal sleep experience, insomnia, the relation of daytime functioning to sleep, parasomnias, circadian rhythm disorders, treatment adherence, pediatrics, and geriatrics. Multidisciplinary approaches are particularly welcome. The journal’ domain encompasses human basic, applied, and clinical outcome research. Behavioral Sleep Medicine also embraces methodological diversity, spanning innovative case studies, quasi-experimentation, randomized trials, epidemiology, and critical reviews.
