The Epworth sleepiness scale (ESS) is a widely used instrument in the subjective assessment of sleepiness. Although there are several translations into Spanish, their equivalence to the original version is questionable.
To assess the reliability and validity of a true translation into Spanish of the ESS in Mexican population.
The ESS was translated into Spanish with the use of standard translation methodology: forward translation, back translation and bilingual committee consensus. It was administered to six groups of subjects of the following categories: narcolepsy, obstructive sleep apnea syndrome (OSAS), major depression with OSAS risk, major depression without OSAS risk, good sleepers and insomniac patients without OSAS risk. Internal consistency and factorial structure of the ESS was estimated. In addition, a comparison between groups of the ESS scores was conducted.
The ESS showed to be composed by only one factor and it also showed a high reliability coefficient (0.89). Likewise patients with narcolepsy or OSAS had the highest scores while good sleepers obtained the lowest scores.
The true translation into Spanish of the ESS showed similar psychometric properties to the original version and, superior to previous Spanish adaptations. Therefore, the ESS is a reliable instrument for the assessment of sleepiness in our population.
Epworth嗜睡量表（ESS）是一种广泛用于主观评估嗜睡程度的工具。虽然已有多个西班牙语译本，但这些译本与原版本的等效性存疑。
评估ESS西班牙语真译本在墨西哥人群中的信度和效度。
采用标准翻译方法将ESS译为西班牙语：正向翻译、反向翻译及双语委员会达成共识。该量表被应用于六组受试者，分别为：发作性睡病、阻塞性睡眠呼吸暂停综合征（OSAS）、有OSAS风险的重度抑郁症患者、无OSAS风险的重度抑郁症患者、睡眠良好者以及无OSAS风险的失眠患者。评估了ESS的内部一致性和因子结构。此外，还对各ESS评分组进行了比较。
ESS显示仅由一个因子构成，且具有较高的信度系数（0.89）。同样，发作性睡病或OSAS患者得分最高，而睡眠良好者得分最低。
ESS的西班牙语真译本显示出与原版本相似的心理测量学特性，且优于先前的西班牙语改编版本。因此，ESS是评估我国人群嗜睡程度的可靠工具。
