1. The sleep quality of medical staff who treated COVID-19 was relatively low compared to general chinese population.
2. Social support indirectly improves sleep quality in medical staff by alleviating their stress and anxiety levels, and increases their self-efficacy.
This information comes from an observational and cross-sectional study which included 180 nurses or doctors from different provinces in China, who have treated COVID-19 patients from January 2020 to February 2020. The data is collected from 5 different types of self-reported questionnaires: the 10-item Social Support Rate Scale, the 20-item Self-Rating Anxiety Scale, the 10-item General Self-Efficacy Scale, the 30-item Stanford Acute Stress Reaction and the 18-item Pittsburgh Sleep Quality Index.
