This research extended current positive psychological research by investigating the mediating effect of shyness on the association between optimism, psychological vulnerability and subjective well-being. Two hundred fifty-five volunteer university students (131 females and 124 males, mean age = 23.14) participated in the study. The structural equation modeling revealed shyness fully mediated the effect of psychological vulnerability on subjective well-being, while shyness partially mediated the effect of optimism on subjective well-being. Also, bootstrapping procedures confirmed that psychological vulnerability was indirectly associated with subjective well-being through shyness, whereas optimism was directly associated with subjective well-being. The implications for future studies and the limitations of the study were discussed in the context of the relevant literature.

测试主观幸福感模型：乐观，心理脆弱和害羞的作用

这项研究通过调查害羞对乐观，心理脆弱性和主观幸福感之间的中介作用，扩展了当前的积极心理学研究。255名志愿者大学生（131名女性和124名男性，平均年龄= 23.14）参加了这项研究。结构方程模型表明，羞怯完全调节了心理脆弱性对主观幸福感的影响，而羞怯则部分调节了乐观对主观幸福感的影响。此外，引导程序证实心理脆弱性与通过害羞导致的主观幸福感间接相关，而乐观与主观幸福感直接相关。
