Dark Triad is a term used to describe a group of three aversive personality traits – Machiavellianism, psychopathy, and narcissism. This study evaluates the utility of the Dark Triad Dirty Dozen for Peruvian adolescents through the evaluation of its psychometric properties; specifically, its factorial structure, measurement invariance according to gender and age group, and reliability. A total of 440 adolescents participated in the study (female: 48.2%; male: 51.8%); their ages ranged from 12 to 17 (Mage = 14; SDage = 1.38). The results showed a three-factor structure invariant by gender and age group and adequate internal consistency, although it was necessary to eliminate item 8. The findings suggest that the 11-item version of the Dark Triad Dirty Dozen is a measure with adequate psychometric properties, reliable and useful for the study of Peruvian adolescents. The theoretical and practical implications of the study are then discussed.
