自我概念在老年人社会支持与主观幸福感间的中介作用

The mediation role of general self-concept between social support and subjective well-being in older adults

目的了解老年人自我概念、社会支持和主观幸福感之间的关系。方法采用中国成年人自我概念量表（GSCS）、社会支持评定量表（SSRS）、纽芬兰纪念大学幸福度量表（MUNSH）对717名老年人进行调查。结果老年人的自我概念总均分为（2．91±0．41）分，社会支持总均分为（35．45±7．12）分，主观幸福感总均分为（11．56±10．31）分，社会支持与自我概念、主观幸福感得分均呈正相关（r=0．43、0．17，均P〈0．05）。自我概念在社会支持与主观幸福感之间具有部分中介作用，Bootstrap输出的95％置信区间为[0．22，0．78]。自我概念在社会支持与主观幸福感间的中介效应为遮掩效应（直接效应1-0．311、间接效应10．501〉总效应f0．19I）。结论社会支持通过老年人自我概念的中介作用影响主观幸福感。

Objective To investigate the relationship between general self-concept, social support and subjective well-being in Chinese older adults.Methods A total of 717 older adults completed the Gen- eral Self-Concept Scale （GSCS）, Social Support Rating Scale（SSRS） and Memorial University of Newfound- land Scale of Happiness（MUNSH） .Results The self-concept score of the elderly was （2.91±0.41） ,social support score was （35.45±7.12） and subjective well-being score was （ 11.56±10.31 ）.Social support was sig- nificantly positively related with self-concept and subjective well-being （r= 0.43 ,P〈0.05 ; r= 0. 17, P〈0.05 ）＋ Self-concept played a partly mediating role between social support and subjective well-being, and the confi- dence interval from Bootstrap output were 95% （0.22,0.78）.The mediating effect between social support and subjective well-being were suppressing effects （ direct effects I - 0.311, indirect effects 10. 50 1 〉 total effects1f0.191 ）.Conclusion Social support can indirectly affect subjective well-being through self-concept.
