The current study examined the sleep quality of Israeli adults following the onset of the Hamas-Israel war, and the associations of reduced sleep quality with the magnitude of war-related anxiety and exposure to adverse war-related events. We also examined whether exposure to stressors during childhood predicts a greater war-related reduction in sleep quality. 536 Israeli adults (mean age 31.4, 209 women) completed an online survey in January 2024, three months into the war. The survey included questionnaires assessing retrospectively childhood harshness (exposure to morbidity and mortality and low socioeconomic status), adverse childhood experiences, and childhood unpredictability. War anxiety was assessed via the war anxiety scale. The participants also completed the Pittsburgh Sleep Quality Index and the Insomnia Severity Index concerning two time points: (a) retrospectively, before the war, and (b) currently, during the war. Participants reported reduced sleep quality and increased symptoms of insomnia during the war. The magnitude of these changes was predicted by exposure to adverse war experiences both directly and indirectly through war-related anxiety. Poorer sleep quality and increased symptoms of insomnia were also indirectly predicted by childhood exposure to morbidity-mortality of close others and childhood unpredictability through greater war-related anxiety. Thus, exposure to the adverse experiences of war, as well as harsh and unpredictable childhoods, could hinder sleep quality during wartime, with these effects mediated by war-related anxiety.
本研究调查了哈马斯-以色列战争爆发后以色列成年人的睡眠质量，以及睡眠质量下降与与战争相关的焦虑程度和接触不良的战争相关事件之间的关联。我们还研究了儿童时期接触压力源是否预示着与战争相关的睡眠质量下降更大。2024 年 1 月，536 名以色列成年人（平均年龄 31.4 岁，209 名女性）完成了一项在线调查，此时战争已经进行了三个月。该调查包括评估 retrospectively 儿童时期的问卷，包括儿童时期的严酷性（接触发病率和死亡率以及低社会经济地位）、不良的儿童经历和儿童时期的不可预测性。通过战争焦虑量表评估战争焦虑。参与者还完成了匹兹堡睡眠质量指数和失眠严重程度指数，共两个时间点：（a）战争前回顾性地，和（b）目前，在战争中。参与者报告在战争期间睡眠质量下降和失眠症状增加。这些变化的幅度直接受到不良战争经历的影响，也通过与战争相关的焦虑间接受到影响。较差的睡眠质量和增加的失眠症状也通过儿童时期接触亲近的人的发病率和死亡率以及儿童时期的不可预测性通过更大的与战争相关的焦虑间接预测。因此，接触战争的不良经历，以及严酷和不可预测的童年，可能会在战时阻碍睡眠质量，这些影响通过与战争相关的焦虑来介导。
