Abstract

Objective. The objective of this study was to adapt the NPI-13 for the Brazilian context, gathering psychometrics evidence. Method. A total of 520 participants completed the NPI-13, the Basic Values Questionnaire, the Five-Factor Inventory, and the Dirty Dozen. Results. The three-factor structure of the NPI-13 (Leadership/Authority, Grandiosity/Exhibitionism, Entitlement/Exploitativeness) was supported (TLI > 0.90; RMSEA < 0.08). Correlations were found between the NPI-13 with achievement values and the dark dyad (i.e., psychopathy and Machiavellianism). The Leadership/Authority and Grandiosity/Exhibitionism factors were consistently correlated with extraversion, while Entitlement/Exploitativeness was correlated with neuroticism. In summary, evidence was gathered for the NPI-13 in the Brazilian context, indicating that it is a useful measure for capturing the multidimensionality of the construct in Brazil.
