Concurrent and convergent construct validities of the 5-item World Health Organization Ageism Experiences Scale in older French Canadians.
Article in The Gerontologist, 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
BACKGROUND AND
objectivesFew instruments have a multi-faceted scope designed to capture several aspects of ageism across diverse contexts, known psychometrics qualities, and are available in multiple languages. The World Health Organization developed the Ageism Scale (WHO-ageism), a 5-item multi-faceted instrument, but its psychometrics qualities and French version are lacking. This study aimed to document the French translation of the WHO-ageism, verify its factor structure and internal consistency, and examine its concurrent construct validity with the Everyday Ageism Scale (EAS) and its convergent validity with social participation and life satisfaction, among older adults living in conventional dwellings (CD) and independent living facilities (ILF). RESEARCH DESIGN AND
methodsThe WHO-ageism was translated according to the Translation, Review, Adjudication, Pretest, and Documentation approach. A cross-sectional survey was carried out with French-speaking adults aged 75+ years (n = 979). The concurrent and convergent construct validities of the WHO-ageism were examined with correlations with the EAS, social participation, and life satisfaction scales.
resultsTranslation was finalized without disagreements. Respondents averaged 82.2 years (SD = 5.4), with two-thirds women. The 5-item version presented a single-factor structure and a minimally acceptable internal consistency. WHO-ageism presented satisfactory convergent validity with the EAS (r = .40; p < .001), among women and men (r = .29 and .43; p < .001), and in CD and ILF (r = .43 and .28; p < .001). It correlated weakly with social participation (r = -.09; p < .01) and life satisfaction (r = -.28; p < .001). DISCUSSION AND IMPLICATIONS: These results demonstrate the WHO-ageism's single-factor structure, internal consistency, and construct validity, supporting its use in large population surveys to inform strategies addressing ageism.
