Psychometric Validation of the Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD) in Slovenia: Implications for Public Health Research and Practice

The ESS-CHAD-SI is a reliable, valid, and culturally adapted instrument for assessing excessive daytime sleepiness in Slovenian adolescents. The identified two-factor structure enhances its clinical and public health relevance by enabling differentiation between sleepiness related to modifiable sleep behaviours and potentially pathological somnolence. The scale is suitable for use in school-based screening, clinical practice, and epidemiological research.
