An Initial Comparison of the Psychometric Properties of the Dark Triad Dirty Dozen in Spanish and Portuguese

Abstract

Abstract. We tested the psychometric properties of the Dark Triad Dirty Dozen measure of psychopathy, narcissism, and Machiavellianism in Portugal ( n = 1,034) and Spain ( n = 386). Adult ( M = 43.40, SD = 14.81, range = 18–88) participants (1,113 women) completed the Dirty Dozen measure of each trait along with ultrabrief measures of extraversion, openness, neuroticism, agreeableness, conscientiousness, and religiousness and a lengthier measure of individual differences in depression, anxiety, and stress. Using confirmatory factor analysis and multigroup confirmatory factor analysis, we found evidence for measurement invariance for a 3-factor model of the Dirty Dozen in the sexes and countries. The Dark Triad traits and disagreeableness were present across the traits and countries. Across depression, anxiety, and stress, correlations with the Dark Triad traits were stronger in men than women. Our results suggest that the scale translations – in each country – are trustworthy paving the way for inter-Iberian and international collaborations.

Taking Stock of Two Years of PTAD – A First Résumé and Outlook

“…To address this, PTAD launched a special issue call in 2022 for the topic “Challenges in Translating and Adapting Psychological Measures to Spanish/Portuguese.” The guest editor team includes experts from Spanish/Portuguese-speaking countries in Europe and South America (Ariela Costa, Ana Carla Crispim, Aristides Ferreira, Nelson Hauk Filho, David Gallardo-Pujol, and Ricardo Primi). A first paper has already been accepted and published (Jonason et al, 2022). To further address the goal of a broad geographical representation, we hereby launch an open call for submitting special issue proposals:…”
