N = 862. Mega-Analytic Findings for fluctuations between baseline narcissism (three-factor structure) and momentary variability in narcissism. Panel 1 shows associations between the narcissism variables (solid lines) controlling for self-esteem (dotted lines). Panel 2 shows associations between narcissism and self-esteem variables (solid lines). Both Panel 1 and Panel 2 are from the same model but portions are greyed out for presentation. Variability in grandiosity and variability in vulnerability are correlated at .30[.21, .36]. Momentary self-esteem and momentary grandiosity are correlated at .29[.21, .36]. Momentary self-esteem and momentary vulnerability are correlated at −.23[−.30, −.16]. Momentary grandiosity and momentary vulnerability are correlated at .26[.20, .32]. FFNI extraversion with FFNI antagonism were correlated at .42 [.36, .47]. FFNI Antagonism and FFNI Neuroticism were correlated at −.03 [−.10, .04]. FFNI extraversion with FFNI neuroticism were correlated at −.10[−.17, −.03]. FFNI = Five Factor Narcissism Inventory.
