Translation, Cultural Validation, and Gender Invariance of the Narcissistic Admiration and Rivalry Questionnaire to Brazilian Portuguese

The “Narcissistic Admiration and Rivalry Questionnaire” (NARQ) assesses narcissism’s admiration and rivalry dimensions. This study aimed at the translation, semantic adaptation, and psychometric validation of the NARQ into Brazilian Portuguese and to check gender invariance. All 789 participants were a convenience sample recruited online from Brazil. After the translation, semantic validation, and back translation, the final version and a socio-economic characterization questionnaire were sent to participants. Exploratory and confirmatory factor analyses were performed. The results confirmed the original model of the questionnaire (χ2 = 580.27, df = 126 (p < 0.001), RMSEA = 0.08 (CI 90% = 0.07–0.08), CFI = 0.99, TLI = 0.99 and χ2/df = 4.60). A configural, metric, and scalar invariance for gender was assessed revealing diverse levels of narcissism for this characteristic. Finally, our version of the NARQ showed adequate validity for this sample preserving the between-gender invariance.
