Factor structure and psychometric properties of the Pathological Narcissism Inventory among Chinese university students.

The Pathological Narcissism Inventory (PNI) is a multidimensional measure of narcissistic pathology. This study examined the factor structure and psychometric properties of the PNI in a sample of Chinese university students in Hong Kong. Eight hundred and thirty-one students completed an online battery of questionnaires assessing narcissistic pathology, self-esteem, unstable sense of self, and maladaptive self-defense strategies. Results replicated the 7 first-order factors and the 2 second-order factors of the PNI. Each of the 7 first-order factors and the 2 second-order factors had good internal consistency. Preliminary findings also supported the concurrent validity of the PNI. The PNI appeared to be a valid measure of narcissistic pathology among Chinese. Findings of this study suggest that the core pathology of pathological narcissism might involve an inflated sense of self-importance that is not substantiated by actual achievement, and bearing this unsubstantiated sense of self-importance renders narcissists highly susceptible to self-deflation when their narcissistic needs are not met.
