Abstract

Objectives

Previous literature has shown that chronic diseases and psychological distress are correlated. However, the mediating and moderating mechanisms underlying this relationship have not been sufficiently studied. The purpose of this study was to explore the role played by activities of daily living (ADL) and perceived social support.

Method

Face-to-face questionnaire-based surveys were conducted with 3250 valid participants (age ≥60 years). Participants were assessed using the Barthel Index, Perceived Social Support Scale, and Depression Anxiety Stress Scale-21.

Results

1) Chronic diseases had a significant direct effect on psychological distress in older adults; 2) the relationship between chronic diseases and psychological distress was partially mediated by ADL; and 3) the impact of chronic diseases on psychological distress was significantly moderated by perceived social support. More importantly, perceived social support was a protective factor that could effectively alleviate the adverse effects of chronic diseases on psychological distress.

Conclusion

The results add to the existing literature by uncovering the underlying mechanisms between chronic diseases and mental health. These findings have implications for early intervention and prevention of mental health problems in older adults.

慢性病对老年人心理困扰的影响：日常生活活动和感知社会支持的中介和调节作用

摘要

目标

以前的文献表明，慢性病和心理困扰是相关的。然而，这种关系背后的中介和调节机制尚未得到充分研究。本研究的目的是探讨日常生活活动 (ADL) 和感知社会支持所起的作用。

方法

对 3250 名有效参与者（年龄≥60 岁）进行了面对面的问卷调查。使用 Barthel 指数、感知社会支持量表和抑郁焦虑压力量表 21 对参与者进行评估。

结果

1）慢性病对老年人的心理困扰有显着的直接影响；2）慢性病与心理困扰之间的关系部分由ADL介导；3) 慢性病对心理困扰的影响被感知到的社会支持显着缓和。更重要的是，感知到的社会支持是一种保护因素，可以有效缓解慢性病对心理困扰的不利影响。

结论

通过揭示慢性病与心理健康之间的潜在机制，该结果丰富了现有文献。这些发现对老年人心理健康问题的早期干预和预防具有重要意义。
