The 7 C Vaccination Readiness Scale: An Empirical Country Comparison Between Germany and Greece.
Article in Journal of epidemiology and global health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundVaccinations are among the most effective interventions against infectious diseases such as measles, influenza, and COVID-19. Nevertheless, there are significant differences in vaccination readiness. The aim of this study was to validate the 7 C scale, which measures seven psychological factors comprising general vaccination readiness, in both German and Greek, and to investigate differences in vaccination behavior between a German and a Greek sample.
methodsA cross-sectional study was conducted with a convenience sample of 576 study participants, of whom 319 responded to the online survey in German and 257 in Greek. Analyses included internal consistency, structural validity, construct validity through the known-groups method, item analysis, and floor and ceiling effects. The two samples differed significantly in terms of demographic data such as age, gender and education, as well as in religiosity and vaccination behavior.
resultsThe German sample showed a higher vaccination rate for most vaccinations, except for vaccinations against hepatitis A, varicella, and meningococcal disease, wheras in the Greek sample, there were significantly more "I don't know" responses regarding vaccination status. The 7 C scale of vaccination readiness demonstrated acceptable to good psychometric properties in terms of both internal consistency and construct validity in both samples, although there were some weaknesses in the component that measures calculation
conclusionThe German and Greek versions of the 7 C scale are invaluable research tools for investigating vaccination readiness. A comprehensive understanding of the underlying factors contributing to vaccine hesitancy is imperative for the development of culturally tailored educational initiatives. These initiatives must be designed to address prevalent misconceptions regarding vaccination, with the objective of enhancing vaccination rates, and promoting public health.
