Psychometric properties of the short dark triad measure

In recent years, negative personality traits have attracted research attention. One of the examples is Dark Triad, which is a constellation of three personality traits: Machiavellianism, narcissism, and psychopathy. Some Dark Triad measures have been created. The article is devoted to the adaptation and validation of the Short Dark Triad (SD3) measure. We examined the structure, reliability, and validity of the items and scales in samples of 459 participants (69,5 % of them were female). Two versions of the questionnaire were offered: the full one (27 items) and the revised one (18 items). The structures of both versions correspond to the original SD3. The alpha reliabilities were 0,72 for Machiavellianism, 0,75 for narcissism, and 0,65 for psychopathy. The test-retest reliabilities were good for Machiavellianism and narcissism, and appropriate for psychopathy. To evaluate the convergent validity of SD3, it was compared with Russian adaptation of HEXACO-60. The Dark Triad traits have negative relationships with Honesty - Humility, Emotionality and Agreeableness. This study indicates that SD3 provides efficient, reliable, and valid measures of the personality traits included in the Dark Triad.
