“…This has both conceptual and measurement implications. It has been suggested that the Dark Triad traits reflect a meaningful and evolutionary relevant latent construct (Jonason et al, 2009), and idea that has received support from overseas researchers (Bertl, Pietschnig, Tran, Stieger, & Voracek, 2017) and those parsing the shared and unique variance using structural equation modelling in relation to important outcomes like sexual assault (Figueredo et al, 2015;Jonason, Girgis, & Milne-Home, 2017). However, recent evidence has also claimed there might not even be three traits but, merely a combined Machiavellianism and psychopathy factor with narcissism standing alone for both the SD3 and the DD measures (Kajonius, Persson, Rosenberg, & Garcia, 2016;Persson, Kajonius, & Garcia, 2017).…”
