Reevaluating Sleep Quality During COVID-19 and Associations With Quarantine, Mental Health, Stress, and Screen Time in Young Adults: Results From a Cross-Sectional Online Survey.

The COVID-19 pandemic affected individual sleep quality, especially with high-stress levels. We assessed sleep quality in young adults during COVID-19, and mental health, stress, and screen time (ST) use. An international cross-sectional study was conducted from September 2020 to January 2021. The surveys assessed sleep quality (PSQI), ST use, and mental health. 183 participants were eligible for analysis. The average global PSQI score was 7.29 (sd = 3.58, n = 99). Associations were found between global PSQI scores and Fear of COVID-19 (r (98) = .223, = .027), anxiety scores (r (99) = -.541, < .001), increased total stress scores (r (88) = .486, < .001), and depression (r (97) = .628, < .001). Those currently quarantining had statistically higher PSQI scores than those who quarantined in the past (F (2,175) = 3.397, = .036), but not for those who did not quarantine. Differences were found between genders for global PSQI (F (4,94) = 2.865, < .027) and poor vs good sleep (X2 (1,98) = 3.982, = .046). There was also a relationship between ethnicity and poor vs good sleep quality (X2 (2,94) = 6.538, = .038). We did not find associations between ST and sleep quality but found poor sleep quality significantly related to mental health during COVID-19. We found no direct evidence that quarantining itself results in poor sleep quality. Interventions need to maximize sleep quality in certain groups, like females and ethnic minorities.
