ABSTRACT

OBJECTIVE:

The aim of this study was to develop a Portuguese-language version of the Epworth sleepiness scale (ESS) for use in Brazil.

METHODS:

The steps involved in creating the ESS in Brazilian Portuguese (ESS-BR) were as follows translation; back-translation; comparison (by a committee) between the translation and the back-translation; and testing in bilingual individuals. The ESS-BR was applied to a group of patients who were submitted to overnight polysomnography in order to identify obstructive sleep apnea-hypopnea syndrome (OSAHS), insomnia and primary snoring. A control group was composed of subjects with a history of normal sleep habits, without reported snoring.

RESULTS:

A total of 114 patients and 21 controls were included. The 8-item scores of the ESS-BR had an overall reliability coefficient of 0.83. The study group was composed of 59 patients with OSAHS, 34 patients with primary snoring and 21 patients with insomnia. One-way ANOVA demonstrated significant differences in ESS-BR scores among the four diagnostic groups (p < 0.001). Post-hoc tests between groups showed that the ESS-BR scores of the patients with insomnia did not differ from those of the controls (p > 0.05). The ESS-BR scores were significantly higher for OSAHS patients and for primary snorers than for controls (p < 0.05). In addition, the scores for OSAHS patients were significantly higher than were those for primary snorers (p < 0.05).

CONCLUSIONS:

The results of the present study demonstrate that the ESS-BR is a valid and reliable instrument for the assessment of daytime sleepiness, equivalent to its original version when applied to individuals who speak Brazilian Portuguese.
RESUMO

OBJETIVO:

Desenvolver uma versão da escala de sonolência de Epworth (ESE) para o português para uso no Brasil.

MÉTODOS:

A versão no português do Brasil (ESE-BR) foi desenvolvida de acordo com as seguintes etapas tradução; retrotradução; comparação entre a tradução e a retrotradução (por um comitê); e aplicação em indivíduos bilíngues. A ESE-BR foi aplicada a um grupo de pacientes submetidos à polissonografia de noite inteira para identificar síndrome da apneia-hipopneia obstrutiva do sono (SAHOS), insônia e ronco primário. Um grupo controle foi composto de indivíduos com história de hábitos normais de sono, sem ronco aparente.

RESULTADOS:

Um total de 114 pacientes e 21 controles foram incluídos. Os 8 itens do ESE-BR tiveram um coeficiente de confiabilidade total de 0,83. O grupo em estudo foi composto por 59 pacientes com SAHOS, 34 pacientes com ronco primário e 21 pacientes com insônia. One-way ANOVA demonstrou diferenças significativas nos escores do ESE-BR entre os quatro grupos diagnósticos (p < 0,001). Testes post hoc entre grupos pareados mostraram que os escores do ESE-BR para insones não diferiram daqueles dos controles (p > 0,05). Os escores dos pacientes com SAHOS e nos roncadores primários foram significativamente maiores que os dos controles (p < 0,05). Além disso, os escores para pacientes com SAHOS foram significativamente maiores do que os daqueles com ronco primário (p < 0,05).

CONCLUSÕES:

Os resultados do presente estudo demonstraram que a ESE-BR é um instrumento válido e confiável para a avaliação da sonolência diurna e equivalente a sua versão original, quando aplicada em indivíduos que falam português do Brasil
