Relations among the trifurcated narcissism domains at trait and state level: Two of a kind?

This study explored narcissistic states using a hierarchical, trifurcated structure, examining state variability and trait-state associations of agentic extraversion, self-centered antagonism, and narcissistic neuroticism. The primary objective was to investigate whether the structural composition of narcissism, well-established in trait data, could be replicated in state data. We examined this structure at both between- and within-person levels in state data, including situation-specific structures of narcissism. The study used data from an experimental study where participants ( N = 189) met in groups of up to four people weekly over six weeks. Multilevel confirmatory factor analyses revealed that the narcissism structure was largely the same at both levels. However, within-person compositions of narcissism differed across affiliative versus controversial situations. In affiliative contexts, grandiosity manifested exclusively through agentic extraversion, with no expression through self-centered antagonism. In controversial settings, agentic extraversion and narcissistic neuroticism exhibited a slight negative association, contrasting the positive association observed across all group meetings. Our results show that narcissistic states exhibited less variability compared to the Big Five and rarely varied above their corresponding trait levels. This research contributes to a refined understanding of narcissism, highlighting the interplay between trait tendencies and situational factors in shaping narcissistic state expressions.
