Relationship between Loneliness and the Image of Ageing:Chain Mediating Effects of Anxiety and Perceived Social Support
摘要
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.关键词
