Reliability and validity of the Turkish versions of Dark Triad Dirty Dozen (DTDD-T), Short Dark Triad (SD3-T), and Single Item Narcissism Scale (SINS-T)

Abstract

The Dark Triad Dirty Dozen (i.e., DTDD), Short Dark Triad (i.e., SD3), and the Single Item Narcissism Scale (i.e., SINS) were adapted into Turkish and validated (N=368). We examined internal consistency, factor structures, and convergent and discriminant validity of the scales using the Mach-IV, LSRP, NPI-16, Rosenberg's self-esteem scale, and Big Five scales. The Turkish versions of the scales had good psychometric properties and can be used in further research.
