Abstract
The article presents the results of validation of the Ukrainian version of the Binge Eating Scale (BES), the psychometric properties of which have not yet been tested among the Ukrainian-speaking population
The BES is a questionnaire designed to identify and diagnose individuals suffering from Binge-eating disorder (BED).
The aim of the work was to check the psychometric properties of the Ukrainian version of BES, to establish the factor structure, internal consistency and constructive validity in the sample of Ukrainian youth.
A cross-sectional study of 87 participants was conducted: students from different higher education institutions who could read and write in the Ukrainian language. To characterize the criterion of validity, the BES was compared with the data of the clinical criteria for BED on DSM-5, which in this study is considered the gold standard for the diagnosis of BED.
The Ukrainian version of BES demonstrated a standardized Cronbach’s alpha of 0.885, showing good internal consistency close to high (0.9).
The split half size was 0.899, indicating a very high split half. The correlation between the halves of the test was 0.766720035, which indicates a fairly high reliability in terms of internal consistency
Factor analysis showed a two-factor structure. This explained only 46.2 % of the variance.
The ROC analysis found that the resulting area under the curve (AUC) was 0.811 (95 % CI: 0.713; 0.887), indicating good model quality.
The results of our study confirm the psychometric reliability of the BES, high design and criterion validity. Thus, the Ukrainian version of BES has psychometric characteristics close to the original.
