Abstract:

This research aims at adapting the “Short Dark Triad (SD3)” inventory, developed by Jones and Paulhus (2014) to the Turkish culture. Research sample consists of 327 university students. Within the scope of linguistic equivalence, Pearson correlations have been found as 0.820 for Machiavellianism,0.791 for Narcissism, and 0,763 for psychopathy. The corrected item-total correlation coefficients ranged from 0.676 to 0.794 for Machiavellianism, from 0.724 to 0.795 for narcissism, and from 0.626 to 0.787 for psychopathy. Item analysis based on the score averages of lower and upper group of 27 % showed that t values belonging to all items were meaningful (p<0.01). Croanbach alpha, test-retest, split halves and Guttman reliability coefficients were found 0.935, 0.920, 0.912 and 0.910 for Machiavellianism; 0.933, 0.890, 0.876 and 0.857 for Narcissism, and 0.910, 0.910, 0.864 and 0.848 for psychopathy. In order to determine the construct validity of SD3, confirmatory factor analysis was conducted. Fit indices were acceptable for the original 3 dimensional model (x²/df=4, RMSEA=0.075, NFI=0.92, CFI=0.92, IFI=0.92). In the light of all results, Short Dark Triad Inventory has been found valid and reliable in the Turkish adult sample.
