Turkish Validity and Reliability Study of Grandiose and Vulnerable Narcissism Fluctuation Scale
Abstract
The objective of this study was to adapt the FLUX and its short form g-FLUX, developed to measure fluctuations between grandiose and vulnerable narcissism, into Turkish as the Grandiose and Vulnerable Narcissism Fluctuation Scale (GVNFS) and its short form (GVNFS-SF), and to examine their validity and reliability. Two studies were conducted with participants aged 18–65 years. Study 1 included 307 participants, and Study 2 included 378 participants. The Five Factor Narcissism Inventory-Short Form, the Basic Personality Traits Inventory, and the Affective Lability Scale were used to assess convergent validity. Internal consistency, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were performed. Findings revealed that the three-factor structure of the GVNFS did not show adequate model fit in CFA. However, considering the scale’s high internal consistency and significant correlations with related measures, this misfit may be attributed to factors such as the number of items and the cognitive complexity of their wording rather than theoretical shortcomings. In contrast, the short form (GVNFS-SF), tested in Study 2, demonstrated strong internal consistency, significant convergent validity, and good model fit. Thus, although the GVNFS requires refinement to improve structural validity, its comprehensive item pool offers potential advantages for future scale development and theoretical contributions in narcissism research. Importantly, the GVNFS-SF emerges as a valid and reliable measure of narcissistic fluctuation for Turkish samples. It provides a brief, accessible, and practical tool for research adopting a dynamic view of narcissism and is suitable for both empirical studies and clinical practice.
