Psychometric Properties of the Norwegian 200-Item Version of the HEXACO Personality Inventory-Revised.
Article in Scandinavian journal of psychology, 2026. 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
This study aimed to investigate the psychometric properties of the Norwegian 200-item version of the HEXACO Personality Inventory-Revised (HEXACO-PI-R). The sample consisted of 460 adults (51.3% women) aged 18-75 years (M = 41.5, SD = 15.3) who completed the instrument online. The average internal consistency was α = 0.89 for domains (range: 0.88-0.92) and α = 0.79 for facets (range: 0.60-0.87). Women had higher Emotionality (d = 1.08) and Honesty-Humility (d = 0.39) scores than men. Honesty-Humility scores increased with age. One month test-retest correlations ranged from 0.90 to 0.95 for domains. Exploratory structural equation modeling provided superior fit compared to confirmatory factor analysis (CFI = 0.928 vs. 0.647). Configural and metric invariance were supported across gender and age, with partial scalar invariance. Convergent validity with the Mini-International Personality Item Pool (Mini-IPIP) was strong for Extraversion, Conscientiousness, and Openness (r = 0.69-0.79). Honesty-Humility showed weak to modest associations attesting to the discriminative validity for this dimension. The Norwegian HEXACO-200 had strong psychometric properties demonstrating its suitability for personality assessment in Norwegian populations.
