Sleep patterns following a natural disaster are associated with mental health difficulties, but research in youth samples has been limited to subjective reports of sleep. Participants (N = 68, 8–17 years old) completed an assessment 6–9 months after Hurricane Harvey, which included subjective measures of sleep, chronotype, hurricane-related post-traumatic stress symptoms, and one week of actigraphy. Prior to the hurricane, parents provided reports on emotional symptoms. Controlling for age, sex, socioeconomic status, participation time, and pre-hurricane emotional symptoms, subjective sleep disturbances and an eveningness chronotype were associated with greater post-traumatic stress, with the strongest effects observed for re-experiencing, negative cognitions/mood, and arousal/reactivity symptoms. Later sleep timing as measured by actigraphy was associated with greater arousal/reactivity symptoms and shorter sleep duration was associated with greater avoidance symptoms. As extreme weather-related events are expected to become more frequent and severe, these findings contribute to models of youth risk and resilience.

自然灾害后的睡眠模式与心理健康问题有关，但对青少年样本的研究仅限于对睡眠的主观报告。参与者（N = 68，8-17 岁）在飓风哈维后 6-9 个月完成了一项评估，其中包括对睡眠、时间型、飓风相关的创伤后应激症状和一周的活动记录的主观测量。在飓风来临之前，父母提供了有关情绪症状的报告。控制年龄、性别、社会经济地位、参与时间和飓风前的情绪症状、主观睡眠障碍和夜间睡眠时间型与更大的创伤后压力相关，观察到重新体验、负面认知/情绪的影响最强，和唤醒/反应症状。通过活动记录仪测量的较晚睡眠时间与更大的觉醒/反应症状相关，而更短的睡眠时间与更大的回避症状相关。随着与极端天气相关的事件预计将变得更加频繁和严重，这些发现有助于建立青年风险和复原力模型。
