Abstract

Background: The aim of this research was to study the VALIDITY and RELIABILITY of the DARK PERSONALITY scale - the form of 12 questions (Jonason & Webster,2010) in a group of Medical Sciences University students (80 females and 65 males). The VALIDITY of the scale was evaluated with item-total correlations (item analysis), subtests correlated with total scores and factor analysis. Scale RELIABILITY by Cronbach’s alpha and split-half RELIABILITY.Results: The correlation of items with total score (0.22 to 0.80) and sub-test with total score (0.75 to 0.83) was significant in all cases (p<0.01). The factor analysis showed three factors Machiavellianism, psychopath and narcissism, which in total explained 63% of variance of DARK PERSONALITY. The Cranach's alpha coefficients for Machiavellianism, psychopath and narcissism and total scores were obtained 0.92, 0.40, 0.68 & 0.81. The split-half RELIABILITY coefficients of Scale was estimated 0.78. Also there was no significant difference between males and females in terms of DARK PERSONALITY. Conclusion: Overall, the results of this study indicated that the scale of DARK PERSONALITY to disease had a good psychometric quality for assessing component of DARK PERSONALITY in Iran.
