Sleep quality of firefighters can be negatively affected by occupational stressors. A cross-sectional investigation was conducted to understand how work-related stress, post-traumatic stress, burnout and depression collectively contribute to sleep quality.
Professional firefighters in Northern Iran completed a survey comprised of demographic information, the Pittsburgh Sleep Quality Index, HSE's Stress Indicator Tool, the Posttraumatic Stress Disorder Checklist, Maslach's Burnout Inventory, and the Beck Depression Inventory during a work rest break. Data were analysed using structural equation modelling.
Mean age of the 2339 firefighters who completed the survey was 32.30 (5.74) years. Most experienced poor sleep quality, scoring above the established cut-off of 5. Levels of work-related stress, post-traumatic stress, burnout and depression were high. Fit indices of the final theoretical model were all adequate: the obtained and adjusted goodness-of-fit indices were 0.925 and 0.917 respectively. Comparative, and incremental fit indices were 0.946 and 0.948 respectively. Root mean squared error of approximation was 0.061. Post-traumatic stress was directly and indirectly related to sleep quality through eight paths, modulated by burnout variables and depression. Work-related stress was negatively related to sleep quality through four paths modulated, by burnout variables and depression.
The findings illustrate the complex relationships of work-related stress and post-traumatic stress and sleep quality. High levels of poor sleep quality in this occupation emphasise the need to develop targeted and sustainable interventions to manage occupational stressors, burnout and depression to improve sleep quality in firefighters.
职业压力因素可能会降低消防员的睡眠质量。本横断面研究旨在探讨工作相关压力、创伤后应激、倦怠和抑郁如何共同影响睡眠质量。
伊朗北部的专业消防员在工间休息时完成了一项调查，内容包括人口统计学信息、匹兹堡睡眠质量指数、HSE 压力指标工具、创伤后应激障碍检查表、马斯拉赫倦怠量表和贝克抑郁量表。使用结构方程模型对数据进行分析。
完成调查的 2339 名消防员的平均年龄为 32.30（5.74）岁。大多数消防员睡眠质量较差，得分高于既定的 5 分 cutoff 值。工作相关压力、创伤后应激、倦怠和抑郁程度较高。最终理论模型的拟合指数均良好：获得的和调整的拟合优度指数分别为 0.925 和 0.917。比较和增量拟合指数分别为 0.946 和 0.948。近似均方根误差为 0.061。创伤后应激通过 8 条途径直接和间接与睡眠质量相关，受倦怠变量和抑郁的调节。工作相关压力通过四条途径与睡眠质量呈负相关，受倦怠变量和抑郁的调节。
这些发现说明了工作相关压力和创伤后应激与睡眠质量之间的复杂关系。该职业中存在大量的睡眠质量差的情况，这强调了需要制定有针对性和可持续的干预措施，以管理职业压力因素、倦怠和抑郁，从而改善消防员的睡眠质量。
