Self-esteem mediates effects of normal and pathological personality traits on subjective well-being

As subjective well-being is foundational to understanding people, researchers have sought to uncover its correlates. Some theorizing proposes that effects of broad personality traits on subjective well-being constructs are mediated by self-esteem; unfortunately, evidence pertaining to this idea has been limited to the study of "normal" broad personality traits and limited measures of subjective well-being. Here, we provided a more comprehensive test of this theory, and we examined the dominance of self-esteem over normal and pathological broad personality traits in predicting an array of subjective well-being constructs. In a primarily college sample (N = 272), we found that self-esteem generally mediated the effects of all Five-Factor Model (FFM) traits except Agreeableness and all pathological personality traits-represented in the Personality Inventory of The Diagnostic and Statistical Manual of Mental Disorders traits (5th edition; PID-5)-except Antagonism on a set of subjective well-being measures; moreover, dominance analyses showed that self-esteem was generally more important than any FFM or PID-5 trait in predicting the subjective well-being measures. We discuss limitations of our study along with some of its basic and applied implications.
