GOMEZ G., Matías et al. Transcultural adaptation and validation of the Epworth sleepiness scale in the Chilean population. Rev. Otorrinolaringol. Cir. Cabeza Cuello []. 2020, 80, 4, pp.434-441. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162020000400434.


Excessive daytime sleepiness (EDS) is associated with different sleep disorders, which in turn causes a significant decline quality of life. Epworth sleepiness scale (ESS) is a frequently used instrument to quantify EDS, but it has not been validated in Chile.


Transcultural and psychometric validation of ESS Chilean version.

Material and Method:

ESS-CL was initially adapted and applied to a pilot group on two separate occasions. Reliability was assessed via Cronbach's alpha and test-retest. ESS-CL was applied to 94 patients with diagnosis of obstructive sleep apnea (OSA) and 100 control to assess its sensitivity.


Reliability values (Cronbach's alpha and test-retest) were 0.732 y 0.837 respectively. The ability to discriminate OSA was 67%.


The ESS-CL is a valid and reliable instrument. A score higher than 11 points is associated with a greater risk of OSA. It is a useful and accessible tool for patients in whom OSA is suspected.
