This study aims to explore the correlation between fear of dementia and insomnia among community-dwelling older adults and to examine the mediating roles of social isolation and resilience on this correlation.
A total of 259 community-dwelling older adults from Mianyang, China were recruited from June 2021 to August 2021 using convenience sampling. The Chinese versions of the Fear of Dementia Scale (FODS), Lubben Social Network Scale (LSNS-6), 25-item Connor-Davidson Resilience Scale (CD-RISC-25) and Athens Insomnia Scale (AIS) were used to collect specific, study-related information from the subjects. Correlations between variables of interest were examined by Pearson analysis, and mediation analysis was conducted to explore the direct, indirect and total effects of the fear of dementia on insomnia vis-à-vis social isolation and resilience.
Results from 259 older adults indicated that fear of dementia and insomnia in older adults are positively correlated, that social isolation and resilience mediate the relationship between them, and that social isolation and resilience also had a statistically significant serial mediating effect.
Fear of dementia is positively related to insomnia in older community-dwelling Chinese adults, but resilience and social support may buffer the negative impact of fear of dementia and improve sleep quality.
Fear of dementia is becoming more and more common in community-dwelling older adults in China, and this emotional response to ageing and disease anxiety may be to blame for the poor sleep quality of some ageing populations. However, social support and resilience may buffer the negative impact of fear of dementia. The findings in this study indicate a need for well-trained community nurses and other health practitioners to implement targeted strategies to reduce insomnia among older adults with fear of dementia. These strategies should strengthen resilience as well as social support.
本研究旨在探讨社区居住的老年人中对痴呆症的恐惧与失眠之间的相关性，并检验社会隔离和心理韧性在这种相关性中的中介作用。
2021年6月至2021年8月，采用便利抽样法从中国绵阳招募了259名社区居住的老年人。使用中文版的痴呆症恐惧量表（FODS）、鲁本社会网络量表（LSNS - 6）、25项Connor - Davidson心理韧性量表（CD - RISC - 25）和雅典失眠量表（AIS）从受试者那里收集与研究相关的具体信息。通过Pearson分析检验感兴趣变量之间的相关性，并进行中介分析以探讨对痴呆症的恐惧相对于社会隔离和心理韧性对失眠的直接、间接和总效应。
259名老年人的结果表明，老年人对痴呆症的恐惧与失眠呈正相关，社会隔离和心理韧性介导了它们之间的关系，并且社会隔离和心理韧性也具有统计学显著的序列中介效应。
在中国社区居住的老年成年人中，对痴呆症的恐惧与失眠呈正相关，但心理韧性和社会支持可能缓冲对痴呆症的恐惧的负面影响并改善睡眠质量。
对痴呆症的恐惧在中国社区居住的老年人中越来越普遍，这种对衰老和疾病焦虑的情绪反应可能是一些老年人群睡眠质量差的原因。然而，社会支持和心理韧性可能缓冲对痴呆症的恐惧的负面影响。本研究结果表明，需要训练有素的社区护士和其他卫生从业者实施有针对性的策略，以减少有痴呆症恐惧的老年人的失眠。这些策略应加强心理韧性以及社会支持。
