Examining the psychometric properties of the Czech versions of Illinois Bully Scale.
Article in Central European journal of public health, 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
objectivesThe main objective of the study was to adapt and verify the psychometric properties of the Illinois Bully Scale (IBS) in Czech adolescents.
methodsThe analysis utilized quantitative data from 1,321 respondents, aged 12 to 14 years, who were enrolled in 7th grade of lower secondary or grammar school. Descriptive and inferential statistics, including chi-square tests and Mann-Whitney U tests, were used to examine group differences.
resultsThe IBS demonstrated strong internal consistency and construct validity across all subscales (Victim: 0.84, Bully: 0.80, Fight: 0.79, total IBS: 0.87). Boys and elementary school students reported significant victim and bully experiences. The supplemental cyberbullying scale showed significant correlations with the IBS subscales, supporting its criterion-related validity.
conclusionsAdaptation of the IBS confirmed that it is a useful tool for assessing the frequency and experience of different types and severity of bullying. Its Czech adaptation allows for population screening as well as identification of severe cases and planning of interventions.
