Abstract: Objective　To explore the chain mediating effect of anxiety and perceived social support on the relationship between loneliness and the image of ageing.Methods　In this study conducted from May to June 2017，we surveyed a random sample of 320 students from Guangxi Nanning University for the Elderly with the Chinese version of Image of Ageing Scale（IAS），Chinese version of Perceived Social Support Scale（PSSS），Chinese version of Anxiety Scale（AS） and Chinese version of Loneliness Scale（LS）．AMOS 20.0 was used to construct the structural equation modeling for analyzing the mediating effect of anxiety and social support on loneliness and images of ageing.Results　293 respondents returned responsive questionnaires，with a response rate of 91.56%.The average score for IAS，PSSS，AS，and LS was（57.6±7.7）（22.8±4.0）（10.9±4.5） and 1（0，2），respectively.Elderly people with poor economic status scored much lower for IAS compared with those with fair economic status（P<0.05）．Correlation analysis showed that perceived social support was positively correlated with image of ageing and anxiety（P<0.05），loneliness was negatively correlated with the image of ageing and perceived social support（P<0.05），and anxiety was positively correlated with loneliness（P<0.05）．Path analysis with multiple mediators demonstrated that loneliness had a positive effect on anxiety（β=0.16，P=0.01），but a negative effect on perceived social support（β=-0.40，P<0.001）；anxiety positively affected perceived social support（β=0.18，P=0.006） as well as the image of ageing（β=0.30，P=0.003）．Mediation analysis with Bootstrapping indicated that in the path of “loneliness→ perceived social support→ the image of ageing”，the estimated value of perceived social support was -0.353 5〔95%CI（-0.685 6，-0.126 8）〕，stating that perceived social support produced partial mediating effects on loneliness and the image of ageing；in the path of “loneliness →anxiety→ perceived social support →the image of ageing”，the estimate value of “anxiety → perceived social support” was 0.028 4〔95%CI（0.004 9，0.088 9）〕，exhibiting that perceived social support and anxiety exerted chain-mediated effect on loneliness and the image of ageing.Conclusion　Anxiety and perceived social support play a chain mediating effect on the relationship between loneliness and the image of ageing.Loneliness indirectly affects the image of ageing through the mediating role of perceived social support，and ultimately predicts it via the mediating effects of anxiety and perceived social support.

摘要： 目的　探讨焦虑、感知社会支持在孤独感和老年人形象之间的链式中介效应。方法　2017年5—6月，采用随机抽样法选取广西南宁市老年大学320例学员，采用老年人形象问卷、感知社会支持问卷、焦虑问卷和孤独感问卷进行调查，采用AMOS 20.0软件构建结构方程模型分析中介效应。结果　共发放问卷320份，回收有效问卷293份，有效回收率为91.56%。老年人形象问卷得分为（57.6±7.7）分，感知社会支持问卷得分为（22.8±4.0）分，焦虑问卷得分为（10.9±4.5）分，孤独感问卷得分为1（0，2）分。家庭经济状况一般者老年人形象问卷得分高于较差者（P<0.05）。感知社会支持与老年人形象、焦虑呈正相关（P<0.05）；孤独感与老年人形象、感知社会支持呈负相关（P<0.05）；焦虑与孤独感呈正相关（P<0.05）。路径分析表明，孤独感对老年人焦虑具有正向影响（β=0.16，P=0.01），对老年人感知社会支持具有负向影响（β=-0.40，P<0.001）；焦虑对老年人感知社会支持具有正向影响（β=0.18，P=0.006）；感知社会支持对老年人形象具有正向影响（β=0.30，P=0.003）。采用Bootstrap检验法检验中介效应，结果显示，“孤独感→感知社会支持→老年人形象”路径中，感知社会支持的估计值为-0.353 5〔95%CI（-0.685 6，-0.126 8）〕，表明感知社会支持在孤独感与老年人形象的部分中介效应成立；“孤独感→焦虑→感知社会支持→老年人形象”路径中，“焦虑→感知社会支持”的估计值为0.028 4〔95%CI（0.004 9，0.088 9）〕，表明感知社会支持与焦虑在孤独感与老年人形象的链式中介效应成立。结论　焦虑与感知社会支持在孤独感和老年人形象之间发挥着链式中介作用。孤独感不仅通过感知社会支持的中介作用对老年人形象产生间接效应，还通过焦虑预测感知社会支持并最终预测老年人形象。
