Self-concept clarity, defined as "the extent to which the contents of an individual's self-concept are clearly and confidently defined, internally consistent and temporally stable" (Campbell Trapnell, Heine, Katz, Lavallee, and Lehman, 1996, p. 141), is a psychological construct tapping the structural aspect of the self. It is a construct that is related closely to but distinguishable from self-esteem. In this study, the relationships of self-concept clarity with impulsivity and hubris were examined. With a sample of 437 students from a mainland China university, self-concept clarity was shown to have differential relationships with different dimensions of impulsivity and hubris. Specifically, individuals high in self-concept clarity were also high in perseverance but low in urgency and hubristic pride. For achieving high self-concept clarity, it seems that having high perseverance but low urgency and hubristic pride is a means to this end.
