Social jetlag and quality of life among nursing students during the COVID-19 pandemic: a cross-sectional study

BACKGROUND: Amid drastic changes in the educational environment and continued substitution of in-person learning with online learning owing to the COVID-19 pandemic, it is important to analyze the predictors of quality of life among nursing students to devise strategies to enhance their quality of life. This study aimed to identify the predictors of nursing students’ quality of life during the COVID-19 pandemic, focusing on social jetlag. METHODS: In this cross-sectional study, data were collected from 198 Korean nursing students in 2021, using an online survey. Chronotype, social jetlag, depression symptoms, and quality of life were assessed using the Korean version of the Morningness-Eveningness Questionnaire, Munich Chronotype Questionnaire, Center for Epidemiological Studies Depression Scale, and World Health Organization Quality of Life Scale abbreviated version, respectively. Multiple regression analyses were performed to identify the predictors of quality of life. RESULTS: Factors affecting participants’ quality of life were age (β = − 0.19, p = .003), subjective health status (β = 0.21, p = .001), social jetlag (β = − 0.17, p = .013), and depression symptoms (β = − 0.33, p < .001). These variables accounted for 27.8% of the variance in quality of life. CONCLUSION: As the COVID-19 pandemic continues, the social jetlag of nursing students has decreased compared to before the pandemic. Nevertheless, the results showed that mental health issues such as depression affect their quality of life. Therefore, it is necessary to devise strategies to support students’ ability to adapt to the rapidly changing educational environment and promote their mental and physical health.
