Recent research has suggested the possibility that self-esteem (SE) may be viewed as a two-dimensional concept consisting of: (a) self-liking, the subjective evaluation of oneself as a social being; and (b) self-competence, the internal conceptions of success and failure in performing tasks (Tafarodi & Swann, 1995). Establishing differential relations between these two dimensions of SE and an important psychological concept like the Big Five, would support the notion of two-dimensional SE. To test this hypothesis the self-liking/self-competence scale (SLCS) and the Big Five Inventory (BFI) were administered to 128 Norwegian college students. The results show a differential relationship between the two dimensions of SE and the personality dimensions of the BFI.
