Validity and reliability of the Spanish version of the Epworth Sleepiness Scale.
Article in Sleep & breathing = Schlaf & Atmung, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe Epworth Sleepiness Scale (ESS) is a brief instrument to identify sleep propensity. However, little is known about the psychometric performance of the Spanish version in university students. The study aimed to study the validity and reliability of the ESS in Colombian university students.
methodsA psychometric study was designed with 465 students of health-related careers between 18 and 29 years old (M = 20.48, SD = 2.27); 66.67% of the students were women. A confirmatory factor analysis was conducted, comparisons of scores between men and women, correlations with insomnia (Athens Insomnia Scale, AIS), anxiety (GAD-7), depression (PHQ-9), and sleep hygiene (SHI-10) and sex differential item functioning as indicators of validity and Cronbach's alpha and McDonald's omega were calculated as estimators of internal consistency.
resultsThe ESS showed a unidimensional structure, similar scores in men and women, statistically significant correlations with AIS, GAD-7, PHQ-9, and SHI-10, without sex differential item functioning, and high internal consistency (Cronabch's alpha and McDonald's omega of 0.82).
conclusionThe Spanish version of the ESS presents acceptable validity and reliability indicators in Colombian university students. However, these findings must be corroborated in other samples of Spanish-speaking participants.
