The Dirty Dozen: A Concise Measure of the Dark Triad
Jonason, Peter K.; Webster, Gregory D.
Psychological Assessment, v22 n2 p420-432 Jun 2010
There has been an exponential increase of interest in the dark side of human nature during the last decade. To better understand this dark side, the authors developed and validated a concise, 12-item measure of the Dark Triad: narcissism, psychopathy, Machiavellianism. In 4 studies involving 1,085 participants, they examined its structural reliability, convergent and discriminant validity (Studies 1, 2, and 4), and test-retest reliability (Study 3). Their measure retained the flexibility needed to measure these 3 independent-yet-related constructs while improving its efficiency by reducing its item count by 87% (from 91 to 12 items). The measure retained its core of disagreeableness, short-term mating, and aggressiveness. They call this measure the "Dirty Dozen", but it cleanly measures the Dark Triad. (Contains 1 figure and 9 tables.)
