Contexte La maladie à coronavirus 2019 (COVID-19), anciennement connue sous le nom de coronavirus 2 du syndrome respiratoire aigu sévère (SRAS-CoV-2) et le nouveau coronavirus 2019 (2019-nCoV), a été identifiée pour la première fois en décembre 2019 dans la ville de Wuhan, en Chine. La modélisation par équation structurelle (MES) est une méthode d’analyse multivariée visant à déterminer la relation structurelle entre les variables mesurées. Cette étude d’observation visait à utiliser le SEM pour déterminer les effets du soutien social sur la qualité du sommeil et le fonctionnement du personnel médical qui a traité des patients atteints de COVID-19 en janvier et février 2020 à Wuhan, en Chine.
Background Coronavirus disease 2019 (COVID-19), formerly known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and 2019 novel coronavirus (2019-nCoV), was first identified in December 2019 in Wuhan City, China. Structural equation modeling (SEM) is a multivariate analysis method to determine the structural relationship between measured variables. This observational study aimed to use SEM to determine the effects of social support on sleep quality and function of medical staff who treated patients with COVID-19 in January and February 2020 in Wuhan, China. Material/Methods A one-month cross-sectional observational study included 180 medical staff who treated patients with COVID-19 infection. Levels of anxiety, self-efficacy, stress, sleep quality, and social support were measured using the and the Self-Rating Anxiety Scale (SAS), the General Self-Efficacy Scale (GSES), the Stanford Acute Stress Reaction (SASR) questionnaire, the Pittsburgh Sleep Quality Index (PSQI), and the Social Support Rate Scale (SSRS), respectively. Pearson’s correlation analysis and SEM identified the interactions between these factors. Results Levels of social support for medical staff were significantly associated with self-efficacy and sleep quality and negatively associated with the degree of anxiety and stress. Levels of anxiety were significantly associated with the levels of stress, which negatively impacted self-efficacy and sleep quality. Anxiety, stress, and self-efficacy were mediating variables associated with social support and sleep quality. Conclusions SEM showed that medical staff in China who were treating patients with COVID-19 infection during January and February 2020 had levels of anxiety, stress, and self-efficacy that were dependent on sleep quality and social support.
