Abstract
ABSTRACT Objective Few studies have investigated the Dark Triad and its impact on behaviour in Saudi Arabia, mostly due to the lack of validated instruments. The aim of this study was to investigate the psychometric properties of the Dark Triad Dirty Dozen, in the context of Saudi Arabia. Method A sample of 1,329 respondents (59.8% female, mean age = 26.79, SD = 8.47) completed a survey containing the Dark Triad Dirty Dozen (DD), the Corruption Propensity Scale and the Propensity to Morally Disengage scale, as well as a demographics questionnaire. Confirmatory factor analysis, measurement invariance across gender, internal consistency reliability analysis, test–retest reliability analysis, and concurrent and convergent validity analyses were performed to validate the DD. Results The CFA supported a three-factor model with adequate factor loadings ranging between 0.29 and 0.83 and sufficient fit indices. The scale was gender invariant. The internal consistency reliability and test–retest reliability were adequate (0.70–0.86 and 0.58–0.75, respectively). Moderate-to-high Pearson correlations supported the convergent and concurrent validity of the scale. Conclusion The Dark Triad Dirty Dozen is a reliable and valid measure that can be used in Saudi Arabia.
