An Exploratory Structural Equation Modeling Approach for the Narcissistic Personality Inventory: Support for the NPI-13 Brief Version and Evidence Based on Relations to Other Variables.
Article in Clinical neuropsychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: The Narcissistic Personality Inventory (NPI) is the most commonly used psychometric instrument for assessing narcissistic traits in the general population. Despite its widespread adoption, various factorial structures have been proposed. The present study aimed to provide new evidence for the NPI factorial solution using the not-yet-explored Exploratory Structural Equation Modeling (ESEM) approach and to improve understanding of its relationship with other variables. Results: The NPI-13 ESEM model was the optimal fitting model (ꭓ2=72.060, df = 42, CFI = 0.979, TLI = 0.961, RMSEA = .035 [.021-.049]) also for its bifactorial solution. Moreover, our findings supported the evidence based on relations to other variables for the NPI-13. Conclusions: In conclusion, our results argued the use of a multidimensional brief version of the NPI and supported the ESEM's advantages for explaining the factorial structure of complex psychological constructs.
