Abstract: Life satisfaction reflects people’s life quality from subjective side. However, the existing researches mostly focus on the elderly, adolescents and those with physical or mental disorders, but few researches conducted on normal adults. Core self-evaluation is an advanced concept of personality, composed of four general concepts which are self-esteem, general self-efficacy, emotional stability and internal control. Many researches showed that core self-evaluation can effectively predicted people’s life satisfaction. However, few researches explored the mechanism how core self-evaluation predict people’s life satisfaction. Getting insight into people’s satisfaction of specific field in the life, we hypothesized core self-evaluation can not only directly affect life satisfaction, but also indirectly affect life satisfaction on the basis of the mediating effect of perceived social support, as from different sources, the perceived social support can have different effect. The purpose of this study was to explore the relationship between core self-evaluation and life satisfaction of employees, as well as test the mediating effects of perceived social support from different sources between the core self-evaluations and life satisfaction in different fields. There were 245 employees to participate in this study. CFA and structural equation modeling were used to test the theoretical model. The results indicated that: (1) core self-evaluation directly and positively predicted job satisfaction and self satisfaction; (2) family support fully mediated the relationship between the core self-evaluation and family satisfaction, and partially mediated core self-evaluation and self satisfaction; friend support fully mediated core self-evaluation and friend satisfaction. From the perspective of perceived social support from different sources, this study explored the mechanism how employees’ core self-evaluation predict their life satisfaction in different fields. It has shown that core self-evaluations directly affect non-relational life satisfaction, while indirectly affect relational life satisfaction on the basis of some kind of perceived social support’s mediating effect. It revealed that the different areas of life satisfaction shouldn’t be treated as the same. Greater influence of personality would work for non-relational life satisfaction, but the family harmony, being understood, and other support is significant for relational life satisfaction. The result of this study makes a contribution to further deepen the understanding of the mechanism of how the core self-evaluation effects on life satisfaction, and also can give some advices to increase life satisfaction and subjective well-being of employees.

摘要： 本研究以245名企业员工为被试，从感知到的不同来源社会支持的角度探索了核心自我评价对员工生活满意度不同领域的作用机制。结果表明：（1）核心自我评价对家庭、朋友、工作和自我满意度均有显著的正向预测作用。（2）家庭支持在核心自我评价与家庭满意度之间起完全中介作用，在核心自我评价与自我满意度之间起部分中介作用；朋友支持在核心自我评价与朋友满意度之间起完全中介作用。研究表明，核心自我评价能直接预测生活满意度中的非关系型领域，能通过各类社会支持分别间接预测生活满意度中的各类关系型满意度。
