German Version of the Epworth Sleepiness Scale

Abstract

Background: The Epworth Sleepiness Scale (ESS) is a questionnaire widely used in English speaking countries for assessment of subjective daytime sleepiness. Objective: Our purpose was to translate and validate the ESS for use in German-speaking countries. Methods: A German translation of the ESS was administered to 159 healthy German-speaking Swiss and to 174 patients with various sleep disorders. Results: The mean ± SD of ESS scores in normals was 5.7 ± 3.0, in patients it was 13.0 ± 5.1 (p < 0.001). Scores were not correlated with age or gender but with the percentage of time spent at an oxygen saturation <90% (R = 0.35, p < 0.001), and the respiratory disturbance index (R = 0.26, p < 0.001) in primary snorers and sleep apnea patients. Item analysis confirmed internal consistency of the scale (Cronbach α = 0.60 in normals, and 0.83 in patients). Follow-up scores in 25 sleep apnea patients on treatment showed a reduction by 7 ± 5 points (p < 0.05). Conclusions: Our data validate the ESS for application in German-speaking populations. The simplicity, reliability and the apparent lack of relevant influences of language and cultural background on performance of the ESS makes it a valuable tool for clinical management and research.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
