The aim of this study was to test the proposed three-factor structure of the Swedish version of the Dark Triad Dirty Dozen measure. A confirmatory factor analysis showed mixed evidence for model fit. In contrast to expectations, men did not score significantly higher than women in Machiavellianism and narcissism. Nevertheless, men scored higher than women in psychopathy.

Background: Humans seem to have a unique ability to consciously organize the flow of time (i.e., past, present, and future) and to intentionally choose goals and values (i.e., character: self, others, the universe). These two parts of human awareness have implications for individuals' relation to a society that will flourish or perish. In fact, a balanced time perspective is suggested as necessary for the experience of well-being and optimal societal functioning. Nevertheless, low character development might be expressed as a Dark Triad: Machiavellianism, narcissism, and psychopathy. In the present study, we aimed to investigate if individuals differ in their outlook on time depending on their dark character profiles. Method: We re-analyzed data from a previous study in which participants (N = 338) responded to the Short Dark Triad Inventory and the Zimbardo Time Perspective Inventory. However, here we use the Dark Cube (Garcia, 2017a), a model of malevolent character based on Cloninger's biopsychosocial theory of personality and in the assumption of a Dark Triad, thus, clustering individuals in eight profiles (i.e., the combination of high/low in three malevolent character traits). Results: The results for each trait suggest multi-finality (i.e., same antecedents, different outcomes) and equifinality (i.e., different antecedents, same outcomes). For example, individuals high in narcissism presented a balanced time perspective when manipulative behavior was also high and psychopathy was low. Conclusions: In certain conditions, malevolent character is associated to a balanced time perspective. Thus, suggesting that in order to understand well-being and optimal societal functioning, we need to look at human awareness in relation to both time (i.e., past, present, future) and space (i.e., character: self, others, the universe).

BackgroundThe Dark Triad (i.e., Machiavellianism, narcissism, and psychopathy) can be captured quickly with 12 items using the Dark Triad Dirty Dozen (Jonason and Webster, 2010). Previous Item Response Theory (IRT) analyses of the original English Dark Triad Dirty Dozen have shown that all three subscales adequately tap into the dark domains of personality. The aim of the present study was to analyze the Swedish version of the Dark Triad Dirty Dozen using IRT.Method570 individuals (nmales = 326, nfemales = 242, and 2 unreported), including university students and white-collar workers with an age range between 19 and 65 years, responded to the Swedish version of the Dark Triad Dirty Dozen (Garcia et al., 2017a,b).ResultsContrary to previous research, we found that the narcissism scale provided most information, followed by psychopathy, and finally Machiavellianism. Moreover, the psychopathy scale required a higher level of the latent trait for endorsement of its items than the narcissism and Machiavellianism scales. Overall, all items provided reasonable amounts of information and are thus effective for discriminating between individuals. The mean item discriminations (alphas) were 1.92 for Machiavellianism, 2.31 for narcissism, and 1.99 for psychopathy.ConclusionThis is the first study to provide IRT analyses of the Swedish version of the Dark Triad Dirty Dozen. Our findings add to a growing literature on the Dark Triad Dirty Dozen scale in different cultures and highlight psychometric characteristics, which can be used for comparative studies. Items tapping into psychopathy showed higher thresholds for endorsement than the other two scales. Importantly, the narcissism scale seems to provide more information about a lack of narcissism, perhaps mirroring cultural conditions.
