Adaptation of the short form of narcissistic personality inventory (NPI-16) into the Ukrainian language: psychometric indicators analysis

Abstract

According to semantic analysis of speech constructions as markers of narcissism in different cultures, the work aims to test and validate the short form of Narcissistic Personality Inventory (NPI-16) among a Ukrainian sample. The short unidimensional measure of the narcissism NPI-16 (NPI-16; Ames, Rose, & Anderson, 2006) reflects four theoretical constructs, based on Emmons (1987) and Ruskin & Terry (1988) theories of narcissism: exploitativeness/entitlement, self-absorption/self-admiration, authority, and self-sufficiency. The study also used the Narcissistic Admiration and Rivalry Questionnaire Short Scale (NARQ-S; Back et al., 2013), the Hypersensitive Narcissism Scale (HSNS; Hendin & Cheek, 1997), and Rosenberg self-esteem scale (RSE; Rosenberg, 1965). The study involved 992 people aged 17 to 60 years (M = 24.97), 26.3% men and 71.5% women (2.2% of respondents did not indicate their gender). The Ukrainian version of the questionnaire was reduced to fourteen statements (NPI-14), because statements №5 and №16 do not contribute to the overall indicator of narcissism in the Ukrainian sample. The α-Cronbach index for NPI-14 is 0.69. The retest reliability shows a high level of reliability of the Ukrainian version. The correlations between NPI-14 scales and the Narcissistic Admiration and Rivalry Questionnaire scales and the Hypersensitive Narcissism Scale testify constructive validity of the Ukrainian NPI-14. The NPI-14 has good internal, discriminant, and predictive validity and can serve as a short measure of narcissism in Ukrainian.
