Up all night: the effect of the COVID-19 pandemic on insomnia among college students.

To investigate COVID-19's impact on sleep, specifically insomnia, in college students. Students from a private university were eligible if they registered for Refresh, an online sleep-health program. A pre-intervention survey was distributed and assessed insomnia and COVID-19 factors using the Insomnia Severity Index (ISI) and a COVID-19 questionnaire. Baseline ISI scores from students enrolled in 2020-2021 were compared to scores from students enrolled in 2018-2019 using a two-sample t-test. Associations between insomnia and the COVID-19 factors were determined using chi-square tests. There was no significant difference in baseline ISI scores when comparing 2018-2019 scores to those collected during the pandemic,  = 0.274. There was a statistically significant association between having insomnia and a student's learning location,  0.006, as well as disturbances in sleep caused by the pandemic,  0.026. Our results indicate that the COVID-19 pandemic did not worsen baseline insomnia.
