Abstract

Objectives: Poor sleep quality and disorders like insomnia are prevalent in the aging population. This mixed-methods study aimed to identify predictors of sleep quality.

Methods: In an online survey, 152 participants aged 65-86 completed questionnaires assessing sleep quality (Pittsburgh Sleep Quality Index [PSQI]), depressive symptoms (Beck Depression Inventory [BDI]), and cognitive reserve (Cognitive Reserve Test [CoRe-T]), alongside a narrative about their sleep experiences.

Results: Demographics, depression, and cognitive reserve (CR) explained 79.3% of the variance in sleep quality. Age and depression predicted poorer sleep, whereas CR was linked to better sleep quality. Depression moderated this effect, reducing CR's protective role. Participants' narratives explained an additional 5.1% of the variance, with negative emotional language predicting poorer sleep and a present or past focus linked to better sleep. Higher CR correlated with more positive emotions and less present focus.

Discussion: Cognitive reserve protects against sleep problems, and subjective reports offer insight into sleep perception, beneficial for prevention and treatment strategies.

研究认知储备、抑郁和睡眠质量之间的相互作用：老龄化人群的混合方法研究。

目的：老年人普遍存在睡眠质量差和失眠等障碍。这项混合方法的研究旨在确定睡眠质量的预测因素。方法：在一项在线调查中，152名年龄在65-86岁之间的参与者完成了评估睡眠质量（匹兹堡睡眠质量指数[PSQI]）、抑郁症状（贝克抑郁量表[BDI]）和认知储备（认知储备测试[CoRe-T]）的问卷调查，并对他们的睡眠经历进行了叙述。结果：人口统计学、抑郁和认知储备解释了79.3%的睡眠质量差异。年龄和抑郁预示着较差的睡眠，而认知储备与较好的睡眠质量有关。抑郁症缓和了这种影响，降低了认知储备的保护作用。参与者的叙述解释了另外5.1%的差异，消极的情绪语言预示着更差的睡眠，而现在或过去的关注与更好的睡眠有关。较高的认知储备与更多的积极情绪和更少的当下注意力相关。讨论：认知储备可以防止睡眠问题，主观报告提供了对睡眠感知的洞察，有利于预防和治疗策略。
