Psychometric properties of the Kogan Attitudes toward Older People Scale: evidence from a German general-population survey.
Article in Frontiers in 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
Introduction: The Kogan Attitudes toward Older People Scale (KAOP) has been translated and validated in numerous languages, although a German version does not yet exist. The present study aimed to translate, adapt, and psychometrically evaluate the KAOP for German-speaking populations. Methods: A convenience sample of 419 participants completed the 34-item German KAOP Scale (KAOP-D-34), 211 of whom took part in the retest after four weeks. Reliability was assessed using internal consistency, item analysis, and test-retest reliability. Structural validity was explored using principal component analysis (PCA), and construct validity was tested using the known-groups method. Convergent validity was assessed utilizing the Aging Semantic Differential (ASD), Age Stereotypes (AS), and Future Selves (FS). Results: The KAOP-D-34 demonstrated good internal consistency ( Conclusion: These results support that the KAOP-D-32 is a psychometrically robust instrument for assessing attitudes toward older adults.
