Recent literature on narcissism argues that there are three factors covering the construct: agentic, antagonistic, and neurotic. Within the current study, we aim to (a) empirically test whether this hypothesized structure reproduces using, for the first time, network psychometrics with eight distinct narcissism measures as well as reanalysing data from eleven narcissism measures from Crowe et al. (2019) and (b) scrutinize the personality underpinnings of the differentiated facets through the lens of the circumplex of personality metatraits (CPM) model. Within the study, N = 465 Polish adults were administered eight distinct narcissism measures, comprising 13 scales capturing different aspects of narcissistic personality and a measure of personality metatraits. Results revealed that the three-factor structure reproduces well in the network approach across both data sets. The circumplex analyses provided further evidence for the personality underpinnings of the three factors. We discuss the role of pathological narcissism within the three-factor conceptualization of narcissism. Findings of the current article facilitate the understanding of narcissistic personality.
Establishing measurement invariance (MI) is vital when using any psychological measurement to ensure applicability and comparability across groups or time points. If MI is violated, differences found by comparing groups could be due to measurement disparity rather than true differences in the latent variable (Chen, 2007). Multi-group confirmatory factor analysis (MGCFA) is one of the most common methods for testing MI, however accurately and comprehensively modeling MI is conceptually difficult (Finch and French, 2008). Schroeders and Gnambs, 2018 found that one out of four studies testing for MI included an inaccurate or inadequately described model, in particular they found that the most influential predictor for errors in MI modeling was software choice. Additionally, unequal sample sizes across groups may impact goodness of fit measures relied on in the testing for MI (Kaplan and George, 1995). In network psychometrics, the available methodology for comparing network structures across groups or time points is not conceptually analagous to MI and relies on the testing of partial correlations. We propose a more conceptually digestable method for testing MI within the Exploratory Graph Analysis (EGA; Golino and Epskamp, 2017) framework. Within EGA, network loadings, which have been shown to be comparable to loadings in factor analysis (Christensen and Golino, 2021) can be computed. We calculate the difference in network loadings between groups and, using permutation testing, compare each original network loading difference to a formulated null distribution to determine significance. The method will be tested on simulated data following commonly found data structures in psychological research, including unequal sample sizes across groups. We will compare the accuracy, \kappa, sensitivity, and specificity to the use of MGCFA on the same simulated data.
