“…Other studies on F2FB and CB have situated Mach in the Dark Triad (comprising Mach along self-promotional narcissism and aggressive and impulsive psychopathy) or Tetrad of personality (Dark Triad extended by sadism, representing deriving enjoyment from others' suffering). These studies often used multiple regression or structural equation models to pinpoint "unique" contributions of each trait in predicting (cyber)bullying behaviors and oftentimes found Mach to be (almost) unrelated to (cyber)bullying after partialing (Brown et al, 2019;Chabrol et al, 2009;Gajda et al, 2022;Gibb & Devereux, 2014;Goodboy & Martin, 2015;Knight et al, 2018;Lau & Marsee, 2013;Nappa et al, 2019;Pabian et al, 2015;van Geel et al, 2017; for exceptions, see Giumetti et al, 2022;Safaria et al, 2020;Schade et al, 2021;Wright et al, 2020). A critique labeled perils of partialing mentions that controlling for shared variances among the traits of the Dark Triad/Tetrad jeopardizes interpretations because partialing also eliminates desired commonalities among the traits (e.g., antagonism; Sleep et al, 2017;Vize et al, 2018).…”
