Abstract: An increasing research suggests that self-esteem serves as a mediator of the relationship between many psychological variables (such as personality, social support) and subjective well-being. However, the relationship between self-esteem and well-being is not linear, which means there are mediation variables between them.Therefore, it is a key point to probe the mediating mechanism in the stability effect of self-esteem.

Key words: self-esteem, self-worth, subjective well-being, self-doubt, depression
