The Unified Narcissism Scale-Revised: Testing Incremental Validity and Shortening the Measure.

Narcissism has had a long history of conceptual and measurement confusion. In this paper, we aimed to assess the incremental and external validity of the Unified Narcissism Scale-Revised (UNS-R), and to determine a prototype short form of the measure that is invariant across cultures. In Study 1, we constructed a 15-item short form prototype that was scalar invariant across four countries (United States, China, Sri Lanka, and Australia). Using this short form, we found the Australian sample to be the most different from the other samples. We speculate this is due to Australia having a more horizontal culture, demonstrating resistance to hierarchy and a stronger endorsement of equality. In Study 2, we assessed the incremental and external validity of the UNS-R long and short form and found it to be a superior measure of grandiose narcissism in terms of strength and cogence of external correlations compared to existing measures, but the Five-Factor Narcissism Inventory-Short Form (FFNI-SF) was a better measure of vulnerable narcissism. In conclusion, we have illustrated the robustness of the UNS-R, and its short form, as a measure of narcissism and, in the process, highlighted important cross-cultural differences.

The Unified Narcissism Scale-Revised: Expanding Measurement and Understanding of Narcissism Across Cultures.

The study of narcissism has been hindered by conceptual, theoretical, and measurement in-consistencies. In this article, we report two studies that tested a novel unified conceptualization and theoretical approach to narcissism using the Unified Narcissism Scale-Revised. Study 1 revised the recently developed Unified Narcissism Scale to construct a preliminary 40-item measure in a sample of 395 American participants (Mage = 41). We confirmed the five-factor first-order model, the two-factor second-order model, and the one-factor third-order model. Study 2 considered the cross-cultural performance of the revised scale in the Chinese language in China (N = 326, Mage = 25.5 years) and in the English language in Sri Lanka (N = 354 Mage = 28.7 years) and constructed a final 35-item measure. In conducting these studies, we have demonstrated the cross-cultural importance of entitlement and self-esteem to the conceptualization of narcissism and suggest that the negative relationship between narcissism and agreeableness may be culture-specific to Western samples (as evidenced by the absence of this relationship in non-Western samples). In this article, we have constructed a measure of narcissism that has refined our understanding of the construct and created a tool to capture this understanding.

Vulnerable narcissism as a mediator of the relationship between perceived parental invalidation and eating disorder pathology.

PURPOSE: Parental invalidation and narcissism have been proposed to play an important role in understanding the etiology of eating disorders. The current research aimed to address two main gaps in the literature. The first aim was to determine the differential associations of grandiose and vulnerable narcissism with eating disorder pathology. The second aim was to find a common mediator between both maternal and paternal invalidation and eating disorder pathology. It was hypothesized that when controlling for vulnerable narcissism, grandiose narcissism would not predict eating disorder pathology. In addition, it was hypothesized that vulnerable narcissism would be a mediator of the relationship between parental invalidation and eating disorder pathology. METHODS: Participants were 352 women aged 18-30 years who were recruited from the general and tertiary student population, and as such constituted a community sample. Participants completed the Invalidating Childhood Environment Scale, Brief-Pathological Narcissism Inventory, Eating Disorder Examination Questionnaire, the Avoidance of Affect Subscale of the Distress Tolerance Scale, and the Emotional Expression as a Sign of Weakness Subscale of the Attitudes Towards Emotional Expression Scale in an online survey. RESULTS: Results showed that, when controlling for vulnerable narcissism, grandiose narcissism was no longer associated with eating disorder pathology. It was also found that parental invalidation had a positive indirect effect upon eating disorder pathology, via vulnerable narcissism. CONCLUSIONS: The findings indicate that vulnerable narcissism is more strongly associated with eating disorder pathology as opposed to grandiose narcissism and help to further elucidate the mechanisms via which parental invalidation might exert its negative effect on eating disorder pathology. LEVEL OF EVIDENCE: A cross-sectional survey (Level V).
