The main objective of this study is to assess the prevalence of sleep disturbance and related psychological factors (stress, anxiety and depression) among frontline nurses in Oman during the COVID-19 pandemic. A cross-sectional and descriptive correlational design using Qualtrics® software was used in this research. Data were collected using the Pittsburgh Sleep Quality Index (PSQI), the Hospital Anxiety and Depression Scale (HADS) and the Perceived Stress Scale (PSS). Logistic regression was performed to identify factors associated with poor sleep quality. Of the 987 frontline nurses who participated, 58.8% (n = 580) reported poor sleep quality. In an examination of PSQI components the mean sleep duration was 7.04 (SD = 1.59) hours per night, and the sleep latency mean was 38.18 min (SD = 31.81). Poor sleep (p < .05) was significantly associated with age, marital status, years of experience, comorbidity, and whether family members or relatives were suspected or confirmed with having COVID-19. Logistic regression showed that poor quality of sleep was significantly associated with stress, anxiety and depression symptoms. Sleep disturbance is a significant problem for frontline nurses working in Oman during the COVID-19 pandemic. Appropriate interventions to maintain the health conditions and reduce sleep disturbance among frontline nurses are needed in order to help support nurses’ work during contagious disease outbreaks. These can be implemented through online workshops and training to enhance nurses’ responses to the pandemic or to any further disease outbreaks.

本研究的主要目的是评估 COVID-19 大流行期间阿曼一线护士的睡眠障碍和相关心理因素（压力、焦虑和抑郁）的患病率。本研究使用了使用 Qualtrics® 软件的横截面和描述性相关设计。使用匹兹堡睡眠质量指数 (PSQI)、医院焦虑和抑郁量表 (HADS) 和感知压力量表 (PSS) 收集数据。进行逻辑回归以确定与睡眠质量差相关的因素。在参与的 987 名一线护士中，58.8%（n  = 580）报告睡眠质量差。在对 PSQI 成分的检查中，平均睡眠时间为每晚 7.04 (SD = 1.59) 小时，平均睡眠潜伏期为 38.18 分钟 (SD = 31.81)。睡眠不好（p  < .05) 与年龄、婚姻状况、经验年限、合并症以及家庭成员或亲属是否被怀疑或确认患有 COVID-19 显着相关。逻辑回归表明，睡眠质量差与压力、焦虑和抑郁症状显着相关。在 COVID-19 大流行期间，睡眠障碍是在阿曼工作的一线护士的一个重大问题。需要采取适当的干预措施来维持前线护士的健康状况并减少睡眠障碍，以帮助支持护士在传染病爆发期间的工作。这些可以通过在线研讨会和培训来实施，以加强护士对大流行或任何进一步的疾病爆发的反应。
