The Epworth Sleepiness Scale: Validation of One-Dimensional Factor Structure in a Large Clinical Sample

Conclusions:Our study confirmed the unidimensionality of the ESS in a large diverse clinical population. Results from this study can be used to justify the interpretation of the ESS within clinical populations, and supports valid comparisons between groups based on the ESS. Future studies are warranted to further understand the items comprising the ESS and potentially eliminate redundant items for increased efficiency in clinical settings.Citation:Lapin BR, Bena JF, Walia HK, Moul DE.
