| Abstract: | The dark triad is a term used to describe a constellation of three socially harmful personality traits: Machiavellianism, psychopathy, and narcissism. The main aim of the present study was to examine the psychometric properties of the Short Dark Triad (SD3) scale, a brief measure of the dark triad, among a sample (N = 412) of male (n = 200) and female (n = 212) at-risk Portuguese youths. Confirmatory factor analysis revealed the three-factor structure of the SD3 obtained an adequate fit, and measurement invariance across gender was demonstrated, although two items per dimension had to be removed. The Portuguese version of the SD3 scale demonstrated satisfactory psychometric properties, specifically the properties of internal consistency, convergent validity, discriminant validity, and known-groups validity, which overall justifies its use among this population. Findings are discussed in terms of the use of the SD3 scale with male and female at-risk youths. |
