The article presents the results of validation of the Ukrainian ver- sion 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 de- signed to identify and diagnose in- dividuals suffering from Binge-eating disorder (BED). The aim of the work was to check the psychometric properties of the Ukrainian version of BES, to es- tablish the factor structure, internal consistency and constructive validity in the sample of Ukrainian youth. A cross-sectional study of 87 par- ticipants was conducted: students from different higher education in- stitutions who could read and write in the Ukrainian language. To char- acterize 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 dem- onstrated a standardized Cronbach’s alpha of 0.885, showing good internal consistency close to high (0.9). The split half size was 0.899, indi- cating a very high split half. The corre- lation between the halves of the test was 0.766720035, which indicates a fairly high reliability in terms of in- ternal consistency. Factor analysis showed a two- factor structure. This explained only 46.2 % of the variance. The ROC analysis found that the re- sulting 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 reli- ability of the BES, high design and criterion validity. Thus, the Ukrainian version of BES has psychometric char- acteristics close to the original.
As the penetration of the Internet into people's lives has increased, there is needed to rethink the diagnostic tools used to diagnose Internet addiction. The very concept of Internet addiction also needs to be rethought, as it currently reflects not the content but the form of addiction. The aim of the work was to develop, evaluate psychometric reliability and validate a new diagnostic instrument for the cyberaddiction diagnosis. The proposed “Yuryeva — Shornikov Cyberaddiction Scale” (YSCAS) consists of 18 statements that are rated on a 5-point Likert scale. The study included 217 people (151 women) aged 19 to 69 years. At the first stage, the internal consistency of the YSCAS scale, external and content validity were assessed, at the second stage we assess stability, constructive and criterial validity. In assessing the internal consistency and homogeneity scale YSCAS Cronbach alpha was 0.84. There is proved the absence of gender influence on the indicators of the proposed scale. Spearman's correlation coefficient between YSCAS and Chen's Internet dependence scale was 0.8044 (p < 0.001), which indicates a high criterial validity. Assessing the constructive validity of the proposed scale, it was found that the YSCAS scale should be considered as a single factor scale, without sub-scales in its structure. The proposed cyberaddiction diagnosing method showed a high-quality prognostic model using ROC analysis: the area under the curve (AUC) was 0.971 (95 % CI 0.88; 1.0). The sensitivity of the scale was 100.0 % with a specificity of 90.4 %. As a result of approbation of the proposed psychodiagnostics method “Yuryeva — Shornikov Cyberaddiction Scale”, it was found that this scale is a reliable and credible approach to diagnose cyberaddiction.
