The objective of this study was to 1) determine the effects of a meditation app on depression and anxiety in adults with sleep disturbance, and 2) explore the potential mediating effects of fatigue, daytime sleepiness, and pre-sleep arousal on the relationship between use of the meditation app and changes in depression and anxiety.
Participants were 239 adults with elevated insomnia symptoms (i.e., scores ≥ 10 on the Insomnia Severity Index) and limited or no previous experience with meditation. Depression, anxiety, fatigue, daytime sleepiness, and pre-sleep arousal were assessed at baseline, four weeks, and eight weeks. Repeated-measures ANCOVAs assessed intervention effects on depression and anxiety. Mediation models were estimated using the PROCESS macro.
Participants in the meditation group had more improvement in depression and anxiety symptoms during the intervention period than did those in the control group. Changes in somatic and cognitive pre-sleep arousal at mid-intervention fully mediated effects on depression and partially mediated effects on anxiety. There were no significant indirect effects of fatigue and daytime-sleepiness on changes in mental health.
A meditation app may improve depression and anxiety in adults with sleep disturbance, with effects being driven by improvements in pre-sleep arousal. Future studies should consider targeting pre-sleep arousal to improve mental health in this population.
本研究的目的是：1）确定一款冥想应用程序对有睡眠障碍的成年人的抑郁和焦虑的影响；2）探讨疲劳、日间嗜睡和睡前觉醒在冥想应用程序使用与抑郁和焦虑变化之间关系中的潜在中介作用。
参与者为239名失眠症状严重（即失眠严重程度指数得分≥10）且之前很少或没有冥想经验的成年人。在基线、四周和八周时评估抑郁、焦虑、疲劳、日间嗜睡和睡前觉醒情况。重复测量协方差分析评估干预对抑郁和焦虑的影响。使用PROCESS宏估计中介模型。
在干预期间，冥想组参与者的抑郁和焦虑症状改善程度高于对照组。干预中期躯体和认知睡前觉醒的变化完全介导了对抑郁的影响，部分介导了对焦虑的影响。疲劳和日间嗜睡对心理健康变化没有显著的间接影响。
一款冥想应用程序可能改善有睡眠障碍成年人的抑郁和焦虑，其效果由睡前觉醒的改善所驱动。未来研究应考虑针对睡前觉醒以改善该人群的心理健康。
