Methods: The ESS-CHAD was translated and back-translated following established cross-cultural adaptation guidelines, and content validity was assessed by eleven experts from relevant clinical and research disciplines. A nationwide sample of 3,314 adolescents (≈52% females), with an overall mean age of 15.4 $±$ 1.7 years, completed the questionnaire. Reliability was evaluated using Cronbach’s α and Guttman’s λ2, and construct validity was examined using exploratory and confirmatory factor analyses. Results: All items met the predefined thresholds for content relevance, while clarity indices were acceptable for the majority of items. Factor analyses indicated that a two-factor model provided a better fit to the data than the original unidimensional structure, distinguishing between passive sleepiness and more clinically concerning manifestations of sleepiness. The ESS-CHAD-SI demonstrated adequate internal consistency. Conclusions: 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 behaviors and potentially pathological somnolence. The scale is suitable for use in school-based screening, clinical practice, and epidemiological research. Uvod: Namen študije je bil zagotoviti ustrezen instrument za ocenjevanje čezmerne dnevne zaspanosti (EDS) pri slovenskih otrocih in mladostnikih s prevodom vprašalnika ESS-CHAD ter psihometrično validacijo njegove slovenske različice (ESS-CHAD-SI). Metode: Vprašalnik ESS-CHAD je bil preveden in vzvratno preveden v skladu z uveljavljenimi smernicami za kulturno adaptacijo, vsebinsko veljavnost pa je ocenilo enajst strokovnjakov z različnih kliničnih in raziskovalnih področij. V nacionalni raziskavi je sodelovalo 3314 mladostnikov (≈ 52 % deklet), s povprečno starostjo 15,4 $±$ 1,7 let. Zanesljivost je bila ocenjena s koeficientoma Cronbach α in Guttman λ2, konstruktna veljavnost pa z eksploratorno in konfirmatorno faktorsko analizo. Rezultati: Vse postavke so dosegle vnaprej določene pragove vsebinske relevantnosti, medtem ko so bili indeksi jasnosti za večino postavk sprejemljivi. Faktorska analiza je pokazala, da se dvofaktorski model bolje prilega podatkom kot izvirna enodimenzionalna struktura, pri čemer loči med pasivno zaspanostjo in klinično bolj zaskrbljujočimi oblikami somnolence. Vprašalnik ESS-CHAD-SI se je izkazal za ustrezno notranje skladnega. Zaključki: ESS-CHAD-SI je zanesljiv, veljaven in kulturno prilagojen instrument za ocenjevanje čezmerne dnevne zaspanosti pri slovenskih mladostnikih. Ugotovljena dvofaktorska struktura povečuje njegovo klinično in javnozdravstveno uporabnost, saj omogoča razlikovanje med zaspanostjo, povezano s spremenljivimi vedenjskimi vzorci spanja, in potencialno patološko somnolenco. Lestvica je primerna za uporabo v šolskih presejalnih programih, klinični praksi in epidemioloških raziskavah. excessive daytime sleepiness questionnaires validation adolescents Slovenia čezmerna dnevna zaspanost vprašalniki validacija mladostniki Slovenija true false false Angleški jezik Slovenski jezik This dataset contains anonymized questionnaire data collected as part of a nationwide psychometric validation study of the Slovenian version of the Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD-SI) From January to March 2024 Neznano 2026-01-14 21:34:21 2026-01-15 10:56:55 2026-03-16 21:57:44 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 271086083 README.txt README.txt README 1 2B14781F0A3309B68B00BA400F3DF982 fe8f12bbfdbc3e92f29cbe19a2871368c7d1833d5faaef1131c63a69835c275c 54479d60-f2d9-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225570 RAZ_Mlakar_Ajda_0.csv RAZ_Mlakar_Ajda_0.csv Raziskovalni podatki 1 C5107CABD888AFD110DEC856E5C52247 53c3fdc0694a2625fa2de0375b06b381455202f347ac2274dcccdaae50fac833 0da1484d-f1f6-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225473 MlakarAjda.pdf MlakarAjda.pdf Raziskovalni podatki 1 5AF1B7E6D9FB7A37FAC2A95AEC0AA09B 81fc018908c22ba6ff618f98fda63b8815823d84d6fb45c905b118eb0fcc1940 f4fc5dcc-07ed-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227812 RAZ_Mlakar_Ajda_0.xlsx RAZ_Mlakar_Ajda_0.xlsx Analize 1 49FA1B20384AD48F8DD79870834B3C04 f499c471900bf4b2bc4d60e5be63f5f1519d4ba43c59edddb60cd67559b71873 2194f77c-f1f6-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225474 Medicinska fakulteta Samoizpolnjeni vprašalnik: Papir/svinčnik 0 0 0
