The Dark Tetrad traits and Self-Concept domains

The aim of this research was to examine the relations between the Dark Tetrad traits (narcissism, psychopathy, Machiavellianism, and sadism) and six domains of self-concept (social, competence, affect, academic, family, and physical self-concept). Using a sample comprised of 210 participants (69.5% women), aged between 18 and 78, the Serbian adaptations of the following instruments were applied: the Short Dark Triad (SD3), the Assessment of Sadistic Personality (ASP), and the Multidimensional Self-Concept Scale (MSCS). The results indicate that narcissism was positively related to all domains of Self-Concept, especially to social and physical self, while psychopathy was negatively related to Self-Concept domains, especially to social self. Machiavellianism was negatively related to social Self-Concept and competence, while sadism was negatively related to competence and academic self-concept. Although narcissism is considered as the "brightest" dark trait, results could indicate biased evaluations of the self in narcissism, which is in line with its grandiose and superior self-view.
