Abstract

Purpose: The Athens Insomnia Scale (AIS) is a widely used and authorized questionnaire for evaluating insomnia symptoms. However, its reliability and validity at high altitudes are uncertain. Therefore, this study aimed to confirm the validity and reliability of AIS during a 3658 m altitude exposure.
Patients and Methods: A total of 387 young Chinese males were enlisted in the acute high-altitude exposure group. They flew for about two hours, climbing from 400 m to 3658 m. The high-altitude-acclimated group consisted of 86 young Chinese men who had lived at least six months at 3658 m altitude. The sleep quality of the acute high-altitude exposure group was evaluated using the AIS before the ascent and after exposure to 3658 m for 24 hours, and one week. The sleep quality of the high-altitude-acclimated group was also assessed. The AIS’s internal consistency, reliability, and validity were evaluated.
Results: The respondents’ quality of sleep significantly decreased after being exposed to 3658 m as opposed to 400 m. Two factors comprised the AIS, according to an exploratory factor analysis: “sleep problem” (items 1– 5) and “daytime dysfunction” (items 6– 8). The Cronbach’s α internal consistency coefficients exceeded 0.8, and the corrected item-total correlations were all greater than 0.5 when the subjects were exposed to 3658 m. The model fit index was well within the criterion. The average variance extracted and composite reliability were all higher than 0.5 and 0.7, respectively. The interclass correlation coefficient was deemed “fair to good” at 0.482, which is greater than the 0.4 threshold. The AIS has satisfactory discriminant validity, as shown by the Fornell-Larcker criterion and cross-loading results. The daytime dysfunction R-square values (> 0.33) show that the frameworks have considerable predictive accuracy.
Conclusion: The AIS exhibits strong consistency, reliability, and validity. The AIS’s features and simplicity make it an essential psychometric tool for high-altitude sleep research.

高海拔地区中国男性青年雅典失眠量表的验证

目的：雅典失眠量表（AIS）是一种被广泛使用和授权的失眠症状评估问卷。然而，其在高海拔地区的可靠性和有效性尚不确定。因此，本研究旨在确认 AIS 在海拔 3658 米暴露条件下的有效性和可靠性：急性高海拔暴露组共招募了 387 名中国年轻男性。高海拔适应组由 86 名在海拔 3658 米处生活过至少 6 个月的中国男性青年组成。在登上海拔 3658 米之前和之后的 24 小时和一周内，使用 AIS 对急性高海拔暴露组的睡眠质量进行了评估。此外，还对高海拔适应组的睡眠质量进行了评估。对 AIS 的内部一致性、可靠性和有效性进行了评估：根据探索性因子分析，AIS 包含两个因子："睡眠问题"（项目 1-5）和 "日间功能障碍"（项目 6-8）。当受试者暴露在 3658 米的环境中时，Cronbach's α 内部一致性系数超过 0.8，校正后的项目-总相关系数均大于 0.5。平均方差提取率和综合信度分别高于 0.5 和 0.7。类间相关系数为 0.482，高于 0.4 的临界值，被视为 "一般至良好"。从 Fornell-Larcker 标准和交叉负荷结果来看，AIS 的判别有效性令人满意。日间功能障碍 R 方值（> 0.33）表明，框架具有相当高的预测准确性：结论：AIS 具有很强的一致性、可靠性和有效性。AIS的特点和简易性使其成为高海拔地区睡眠研究的重要心理测量工具。关键词：雅典失眠量表；高海拔地区；内部一致性；可靠性；睡眠；有效性

期刊介绍： Nature and Science of Sleep is an international, peer-reviewed, open access journal covering all aspects of sleep science and sleep medicine, including the neurophysiology and functions of sleep, the genetics of sleep, sleep and society, biological rhythms, dreaming, sleep disorders and therapy, and strategies to optimize healthy sleep. Specific topics covered in the journal include: The functions of sleep in humans and other animals Physiological and neurophysiological changes with sleep The genetics of sleep and sleep differences The neurotransmitters, receptors and pathways involved in controlling both sleep and wakefulness Behavioral and pharmacological interventions aimed at improving sleep, and improving wakefulness Sleep changes with development and with age Sleep and reproduction (e.g., changes across the menstrual cycle, with pregnancy and menopause) The science and nature of dreams Sleep disorders Impact of sleep and sleep disorders on health, daytime function and quality of life Sleep problems secondary to clinical disorders Interaction of society with sleep (e.g., consequences of shift work, occupational health, public health) The microbiome and sleep Chronotherapy Impact of circadian rhythms on sleep, physiology, cognition and health Mechanisms controlling circadian rhythms, centrally and peripherally Impact of circadian rhythm disruptions (including night shift work, jet lag and social jet lag) on sleep, physiology, cognition and health Behavioral and pharmacological interventions aimed at reducing adverse effects of circadian-related sleep disruption Assessment of technologies and biomarkers for measuring sleep and/or circadian rhythms Epigenetic markers of sleep or circadian disruption.
