Abstract
The main objective of the study was to adapt and verify the psychometric properties of the Illinois Bully Scale (IBS) in Czech adolescents.
The 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.
The 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.
Adaptation 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.
