Abstract

Objective: Poor sleep among young adults is prevalent, yet the mediating variables are largely understudied, and there is limited relevant work utilizing objective sleep measures. The present study investigated the mediating effects of perceived stress and rumination in the relationship between trait mindfulness and subjective and objective sleep quality in young adults.
Methods: A total of 170 healthy adults (aged 18– 37, M = 20.8, SD = 2.9) self-reported on trait mindfulness, perceived stress, and rumination. The primary (N = 140) and secondary (N = 30) samples both completed the Pittsburgh Sleep Quality Index (PSQI) to assess subjective sleep quality. The secondary sample (N = 30) additionally provided sleep diaries, as well as wrist-worn actigraphy data for assessing objective sleep quality. A mediation analysis was conducted to assess the effect of trait mindfulness on sleep quality with perceived stress and rumination as mediators.
Results: Trait mindfulness was positively associated with better subjective sleep quality; this was fully mediated by perceived stress, b = − 0.08, 95% CI [− .12, − 0.06]. Rumination was negatively associated with subjective sleep quality but did not mediate the relationship between trait mindfulness and sleep quality, b = − 0.01, 95% CI [− .03, 0.02]. Only trait mindfulness was correlated with diary-based sleep ratings, and none of the measures were associated with actigraphy-based sleep quality.
Conclusion: This study indicates that perceived stress is an important mediator in the relationship between trait mindfulness and subjective sleep quality among young adults, rather than rumination. These findings have implications for mindfulness-based therapeutic approaches to address the high prevalence of sleep disorders among young adults, adding mechanistic detail to the literature.

觉察到的压力（而非反刍）能调节年轻成年人的特质正念与睡眠质量之间的关系

目的：睡眠质量差在年轻人中很普遍，但对其中介变量的研究却很少，利用客观睡眠测量方法进行的相关研究也很有限。本研究调查了感知到的压力和反刍在年轻人的特质正念与主观和客观睡眠质量之间的中介效应：共有 170 名健康成年人（18-37 岁，M = 20.8，SD = 2.9）对正念特质、感知压力和反刍进行了自我报告。主要样本（N = 140）和次要样本（N = 30）均完成了匹兹堡睡眠质量指数（PSQI），以评估主观睡眠质量。次要样本（N = 30）还提供了睡眠日记和腕戴式动电仪数据，以评估客观睡眠质量。我们进行了一项中介分析，以评估正念特质对睡眠质量的影响，并以感知压力和反刍作为中介：结果：特质正念与更好的主观睡眠质量呈正相关；这完全受感知压力的调节，b = - 0.08，95% CI [- .12，- 0.06]。反刍与主观睡眠质量呈负相关，但并不介导正念特质与睡眠质量之间的关系，b = - 0.01，95% CI [- .03, 0.02]。只有正念特质与基于日记的睡眠评分相关，而所有测量指标都与基于动图的睡眠质量无关：本研究表明，在年轻人的正念特质与主观睡眠质量之间的关系中，感知到的压力是一个重要的中介因素，而不是反刍。这些发现对以正念为基础的治疗方法解决年轻人睡眠障碍高发问题具有重要意义，为相关文献增添了机制细节。

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.
