Five-factor model trait profiles of narcissistic grandiosity and narcissistic vulnerability in Iranian university students

This study examined the relationship between pathological narcissism, narcissistic grandiosity, narcissistic vulnerability and the five-factor model of personality. Participants consisted of 290 undergraduate students from four universities in three different cities in Iran, recruited by available sampling, Instruments, including, Pathological Narcissism Inventory (PNI) and the NEO Five-Factor Inventory (NEO-FFI) were also completed for the participants. Hierarchical regression analysis showed that narcissistic grandiosity was positively associated with extraversion and openness, while narcissistic vulnerability and overall pathological narcissism were positively associated with neuroticism and negatively related to agreeableness and openness (only for narcissistic vulnerability). The results are consistent with prior research in Western cultures (e.g., United States, Germany) and revealed that neuroticism is a common factor in narcissistic vulnerability and pathological narcissism which suggested pathological narcissism may be a distinct dimension from normal narcissism. Also, there were various contributors of personality traits for narcissistic grandiosity and narcissistic vulnerability which can be considered as a support for the distinction of two phenotypes of pathological narcissism.
