Seeking a Common Framework for Research on Narcissism: An Attempt to Integrate the Different Faces of Narcissism Within the Circumplex of Personality Metatraits

The current paper presents a proposal for integrating different narcissism constructs (grandiose, vulnerable, communal, and collective) within the Circumplex of Personality Metatraits (CPM), an integrative model of personality structure that could also be used to accommodate the narcissism spectrum model. The study was conducted on a community sample (N = 781 adults). The theoretically predicted locations of the different narcissism constructs within the CPM space were empirically verified using the structural summary method. We found that grandiose, vulnerable, and communal narcissism can be meaningfully located within the CPM, while the status of collective narcissism remains unclear. Thus, the CPM can serve as a personality matrix explaining the differences and similarities between the various faces of narcissism. © 2019 European Association of Personality Psychology     

Some comments on selecting the best of several binomial populations or the bivariate normal population having the largest correlation coefficient

Using variance stabilizing transformations, this note describes approximate solutions to the ranking and selection problem of selecting the best binomial population or the bivariate normal population with the largest correlation coefficient.
