Abstract


This study aimed at cross-validation of Dark pentad personality traits model among Iranian sample. Being socially maladaptive and irritating, Dark personality model is of traits that are associated with a range of negative consequences. The Dark Pentad Personality Traits Model expands upon the dark tetrad model, adding the component of spitefulness to the personality constellation of the narcissism, Machiavellianism, psychopathy and sadism. The present correlational research studies the research population from Azarbaijan Shahid Madani University in the academic year 2017-2018 and the sample size consisted of 400 people who were selected by using cluster sampling methods. The instruments used in this study included the Persian version of Dirty Dozen Scale, the Persian version of Short Sadistic Impulse Scale, and the Persian version of Spitefulness scale. The data were analyzed in two stages. First, Exploratory factor analysis revealed five components of Machiavellianism, psychopathy, narcissism, sadism, and spitefulness, which could finally explain 59.12% of the total variance. Also Confirmatory factor analysis confirmed the Five-Factor Model and showed good fitness of the model; all fitness indices were higher than the critical value of 0.9. The internal consistency coefficients of the items through Cronbach’s alpha for the components ranged from 0.74 to 0.86 and for total items was 0.77. Test-retest reliability coefficients were 0.75 for total items, and between 0.70 and 0.79 for the components. Dark pentad personality traits model was confirmed in the Iranian sample and can be evaluated in clinical and research settings.
