本研究旨在了解中国农村老年人心理困扰的患病率。此外，我们还将探讨社会支持在功能障碍与心理困扰之间的中介作用，以及这种中介作用是否随年龄的变化而变化。对中国山东省某农村地区60-89岁的741名老年人进行了横断面调查。通过问卷调查的方式评估他们的心理困扰、感知到的社会支持、制定的社会支持和功能障碍。217例（29.3%）农村老年人存在心理困扰。≥75岁人群的功能障碍对心理困扰的总影响（0.18）小于<75岁人群（0.30）。功能障碍对≥75岁人群心理困扰的影响主要通过社会支持尤其是感知支持的中介作用间接产生（0.12，占总效应的66.67%），而功能障碍的直接影响不显著。而功能障碍对<75岁人群心理困扰的直接影响最大（0.29，占总影响的96.67%），而社会支持的中介作用不显著。综上所述，功能障碍对心理困扰的总影响，尤其是直接影响，随着年龄的增长而急剧下降。社会支持在功能障碍和心理困扰之间的中介作用随年龄的变化而变化，仅在≥75岁的人群中发现。
This study aimed to determine the prevalence of psychological distress among elderly people in rural China. Moreover, the mediating effect of social support on the association between functional disability and psychological distress and whether this effect varies with age would be examined. A total of 741 elderly people aged 60–89 years from a rural area of Shandong Province, China participated in a cross-sectional survey. Their psychological distress, perceived social support, enacted social support, and functional disability were assessed through questionnaires. A total of 217 (29.3%) rural elderly people had psychological distress. The functional disability of people ≥75 years old had smaller total effects (0.18) on their psychological distress than in people <75 years old (0.30). Moreover, most of the effects of functional disability on psychological distress among the people ≥75 years old were indirect (0.12; 66.67% of total effects) through the mediating effect of social support especially perceived support, while the direct effect of functional disability was insignificant. In contrast, most of the effects of functional disability on psychological distress among the people <75 years old were direct (0.29; 96.67% of total effects), while the mediating effect of social support was insignificant. In conclusion, the total effect of functional disability, especially the direct effect, on psychological distress decreases sharply with age. The mediating effect of social support on the association between functional disability and psychological distress varies with age and is only found in people ≥75 years.
