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).

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 ( = 41).

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.
