Grandiose and Vulnerable Narcissism and the DSM-5 Pathological Personality Trait Model

The Diagnostic and Statistical Manual of Personality Disorders (4th ed., American Psychiatric Association, 2000) personality disorders (PDs) that will be included in the DSM5 will be diagnosed in an entirely different manner; the explicit criterion sets will be replaced with impairments in self and interpersonal functioning and personality traits from a 25-trait dimensional model of personality pathology. From a trait perspective, narcissistic personality disorder (NPD), the focus of this study, is assessed using 2 specific traits: grandiosity and attention seeking. Using a sample collected online from Amazon's Mechanical Turk (MTurk; N = 306), we examined the relations among traits from a new measure of DSM5's trait modelthe Personality Inventory for DSM5 (PID5; Krueger, Derringer, Markon, Watson, & Skodol, in press)and grandiose and vulnerable narcissism. The 25 traits from PID5 captured a significant portion of the variance in grandiose and vulnerable factors, although the 2 specific facets designated for the assessment of NPD fared substantially better in the assessment of grandiose rather than vulnerable narcissism. These results are discussed in the context of improving the DSM5's ability to capture both narcissism dimensions.
