The CATI got a median concurrent authenticity for the thirteen identification disease scales to your Millon Health-related Multiaxial Directory regarding roentgen=0.58. T-ratings was determined for every single of PD balances predicated on CATI norms.

6. Results and Conversation

6.1 Reliability The inner texture from measure score on the strategies applied within data was basically good to expert. 84, 0.80, and 0.93 correspondingly. Cronbachs leader into the antisocial, borderline, histrionic, and narcissistic PD bills have been ?=0.85, 0.83, 0.79, and you can 0.77 correspondingly.

6.2 Sex differences in the dark triad To test the first two hypotheses, a series of independent samples t-tests were conducted to determine if sex differences existed in mean scores for each of the Dark Triad traits and in T-scores for each of the cluster B PD subscales. With regard to the three Dark Triad traits, as hypothesized, men (M=2.79, SD=0.46) scored higher than women (M=2.60, SD=0.46) on Machiavellianism (Mach-IV), t(659)=5.33, p < 0.001 (correlation coefficient of effect size rY ?=0.203, medium effect size), and men (M=2.56, SD=0.53) also scored significantly higher than women (M=2.22, SD=0.51) on psychopathy (SRP-III), t(659)=8.41, p < 0.001 (rY ?=0.311, large effect size). Contrary to the hypothesis, there was no significant difference between men (M=2.99, SD=0.60) and womens means (M=2.92, SD=0.48) on narcissism (NPI), t(659)=1.52, p=0.13 (rY ?=.059, negligible effect size). The results for Machiavellianism and psychopathy are consistent with the previous literature [1, 4, 5]. These results are not surprising and undoubtedly reflect genetic predispositions and cultural influences, at least based upon current Western culture. The lack of a significant difference between men and women on trait narcissism (NPI) is somewhat surprising and will be discussed below.
