There is burgeoning evidence showing the negative impact of fear of COVID-19
on various mental health outcomes. Little is known about the underlying
mechanism of the relationship between fear of COVID-19 and sleep problems in
times of health crisis. This study aims to examine whether fear of COVID-19
was associated with sleep problems through happiness and problematic social
networking sites (SNS) use. Participants included 506 young adults (67.6%
females; mean age = 28.23 ? 8.73 years) drawn from the general public in
Turkey. Results showed that fear of COVID-19 had a significant predictive
effect on happiness (? = -0.15, p < 0.01), problematic SNS use (? = 0.32, p
< 0.01), and sleep problems (? =0.36, p < 0.01)0. Most importantly,
happiness (effect = 0.02, 95% CI [0.01, 0.04]) and problematic SNS use
(effect = 0.07, 95% CI [0.04, 0.11]) mediated the impact of fear of COVID-19
on sleep problems. These findings suggest that happiness and problematic SNS
use are important factors that can help explain the association between fear
of COVID-19 and sleep problems among young adults. Intervention and
prevention programs can be developed to reduce the effect of fear the of
COVID-19 pandemic on sleep problems of young adults by considering the roles
of happiness and SNS use in the context of health crises or other stressful
situations.
