116. Examining the Hierarchical Structure of Narcissism Personality Disorder and Related Interpersonal Profiles
Prior studies have evidenced that conceptualizing narcissism as a global construct can be misleading, as there a divergent conceptualizations and multiple underlying dimensions. Though it is common to formulate narcissism using the vulnerable and grandiose subtypes, more recent studies have shown evidence for a trifurcated model of narcissism comprised of interpersonal antagonism, neuroticism, and agentic extraversion. In this study, we examined how the three underlying factors and overarching subtypes differ in their social characteristics using multiple interpersonal surfaces, given that narcissism is characterized by maladaptive interpersonal functioning. We used facets from the Five Factor Model to capture the various conceptions of narcissism and structured summaries to examine the interpersonal profiles of the components. We recruited 477 participants using MTurk. The three components varied in their interpersonal characteristics, with neuroticism associated strongly with coldness, extraversion associated strongly with dominance, and interpersonal antagonism placed in between the other two components. Overall, our findings highlighted the value and utility of the trifurcated model of narcissism in unpacking the nuances of interpersonal differences among narcissistic individuals.
