The Correspondence of DSM-5 Alternative Model of Personality Disorders with Grandiose and Vulnerable Narcissism

The aim of present study was to investigate the correspondence of Alternative Model of Personality Disorders (AMPD) dimensions with vulnerable and grandiose narcissism. The resaerch method  was a discriptive and correlatinal study. To this end 261 students  from Tabriz University were selected by random cluster sampling and completed the Personality Inventory for DSM-5 (PID-5) and Pathological Narcissism Inventory. The Pearson correlation coefficient and multiple regression were used to analyze data. Results revealed that all dimensions and total score of vulnerable narcissism were correlated significantly with five pathological personality traits; but dimensions and total score of grandiose narcissism were mostly correlated  with antagonism and psychoticism significantly. Regression analysis of vulnerable narcissism showed that four pathological personality trait, including  negative affect, antagonism, disinhibition and psychoticism were significant predictor of total score of vulnerable narcissism, and with regard to dimension of vulnerable narcissism the same four aforementioned dimensions were predictor of contingent self-esteem; detachment and psychoticism were significant predictor of hiding the self; psychoticism was significant predictor of devaluing; and all pathological traits were significant predictor of entitlement rage. With respect to grandiose narcissism regression analysis revealed that antagonism and psychoticism were significant predictor  of grandiose narcissism total score; and with respect to its dimensions, antagonism was significant predictor of exploitativeness; and psychoticism was significant predictor of Self-Sacrificing Self-Enhancement, and also significant predictor of grandiose fantasy. It can be concluded that DSM-5 AMPD relatively corresponds with grandiose and not with vulnerable narcissism.
