A Psychometric Analysis of the Polish Online Version of the Aging Semantic Differential Scale (ASD).
Article in Journal of multidisciplinary healthcare, 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: Nursing students will become professionals providing direct care to an aging population in the future. Given that students' attitudes evolve during their studies, an important element of medical education should be addressing the issue of ageism, verifying false beliefs, promoting the subjectivity as well as individuality of older people in the education process. The aim of the study was to analyse the psychometrics of the Polish online version of the Aging Semantic Differential Scale (ASD). Methods: The study was conducted among 384 students of bachelor's and master's degree studies in nursing (94.3%) and other medical disciplines: midwifery and emergency medical services (5.7%). Theoretical validity of the scale was assessed using principal component analysis (PCA) with Oblimin rotation with delta parameter equal to 0 and Kaiser normalization. Discriminant validity of the obtained factors was calculated using the AVE (Average Shared Squared Variance) and MSV (Maximum Shared Squared Variance) parameters. Reliability of the scale was assessed by determining the internal consistency using Cronbach's Alpha coefficient. Results: A four-factor model was extracted from the analysis. The validity of the analysis was confirmed by the KMO value = 0.88 and a significant statistical result for Bartlett's sphericity test: χ Conclusion: The study contributes to the cross-cultural validation of the ASD scale. We obtained a shorter version than the original ASD scale through statistical calculations. The shorter version of the ASD scale is easier and faster to administer. The scale can be reliably used by researchers and practitioners in disciplines other than nursing.
