Firefighters are at increased risk for posttraumatic stress disorder (PTSD) symptoms and sleep disturbances due to occupational trauma exposure as well as the nature of their job (e.g., shift work, workplace stress). PTSD symptoms co-occur with sleep disturbances, including poor sleep quality, short sleep duration, and low sleep efficiency. No published studies have examined subgroups of firefighters based on PTSD symptoms and sleep disturbances. Thus, we used latent profile analysis to identify the best-fitting class solution to categorize firefighters based on endorsed PTSD symptoms and sleep disturbances and examined relations between the optimal class solution and health covariates (i.e., anger reactions, depression symptoms, emotion regulation difficulties, number of traumatic event types). The sample included 815 trauma-exposed firefighters (M = 38.63; 93.20% male). Results indicated three latent subgroups: High PTSD-Sleep Disturbances, Moderate PTSD-Sleep Disturbances, and Low PTSD-Sleep Disturbances. Multinomial logistic regression indicated that endorsing greater anger reactions, depression symptoms, and emotion regulation difficulties increased the chances of being in the more severe classes. Endorsing greater number of traumatic event types increased the chances of being in the Moderate vs. Low PTSD-Sleep Disturbances Classes. Findings improve our understanding of subgroups of firefighters based on PTSD and sleep disturbances and underscore the importance of addressing depression symptoms, anger management, and emotion regulation skills for firefighters reporting more severe PTSD symptoms and sleep disturbances.
消防员由于职业创伤暴露以及工作性质（例如，轮班工作、工作场所压力）而面临更高的创伤后应激障碍（PTSD）症状和睡眠障碍风险。PTSD 症状与睡眠障碍同时发生，包括睡眠质量差、睡眠时间短和睡眠效率低。没有发表的研究根据 PTSD 症状和睡眠障碍对消防员进行亚组分析。因此，我们使用潜在剖面分析根据 PTSD 症状和睡眠障碍对消防员进行最佳拟合类别分析，并检查最优类别解决方案与健康协变量（即愤怒反应、抑郁症状、情绪调节困难、创伤事件类型数量）之间的关系。该样本包括 815 名创伤暴露的消防员（M=38.63；93.20%为男性）。结果表明存在三个潜在的亚组：高 PTSD-睡眠障碍、中 PTSD-睡眠障碍和低 PTSD-睡眠障碍。多项逻辑回归表明，愤怒反应、抑郁症状和情绪调节困难的程度越高，处于更严重类别的可能性就越大。报告更多创伤事件类型的可能性越高，处于中度 PTSD-睡眠障碍组的可能性就越大，而不是低度 PTSD-睡眠障碍组。研究结果提高了我们对基于 PTSD 和睡眠障碍的消防员亚组的理解，并强调了为报告更严重 PTSD 症状和睡眠障碍的消防员解决抑郁症状、愤怒管理和情绪调节技能的重要性。
