Аннотация:The factor structure of the Short Dark Triad or SD3 questionnaire (Jones, Paulhus, 2014) was investigated using a sample of adolescents. The SD3 is a time-efficient method designed for the assessment of three overlapping negative personality traits: Machiavellianism, subclinical narcissism, and subclinical psychopathy (Paulhus, Williams, 2002). Conceptually, the questionnaire is based on the idea that Machiavellianism, narcissism, and psychopathy, while being relatively independent constructs, nonetheless have a common core and a similar manifestation in interpersonal relationships, and exacerbate the negative influence of other Dark Triad traits. The questionnaire’s psychometric characteristics were obtained using a sample of adults. A detailed analysis of the questionnaire’s factor structure in adolescents is available only for a translated version of the questionnaire (Somma et al., 2019). Our study was conducted with 393 participants (average age 15.37, SD=1.17, 54% female). The participants completed 1) the Russian edition of the SD3, previously validated for adults (Egorova et al., 2015), and 2) a personality inventory (Short Portrait Big Five Questionnaire). When comparing the means, no significant differences were found between the younger (grades 8-9) and older (grades 10-11) groups. An analysis of the structure of the SD3 showed that 7 questionnaire items contribute simultaneously to different scales. 4 of these items are meant for diagnosing psychopathy. When analyzing the interrelations between Dark Triad traits, narcissism was not shown to have a significant correlation with Machiavellianism. When comparing the Dark Triad to the Big Five, no correlation was observed between narcissism and Agreeableness
