| Abstract | VALIDATION OF THE BRAZILIAN PORTUGUESE VERSION OF THE EPWORTH SLEEPINESS SCALE Introduction: The Epworth Sleepiness Scale (ESS) is widely used for the assessment of daytime sleepiness in patients with sleep disorders. The aim of this study was to develop a Brazilian Portuguese version of ESS. Methods: The Brazilian Portuguese version (ESS-BR) was developed according to the following steps: a) translation; b) back-translation; c) comparison between translation and back-translation performed by a comitee; d) testing in bilingual individuals. Between January 2006 and September 2007, the ESS-BR was applied to a group of consecutive patients who were submitted to overnight polysomnography with a clinical suspicion of obstructive sleep apnea syndrome (OSAS), insomnia or snoring. The control group was composed of subjects with a history of normal sleep habits, without apparent snoring. Results: A total of 114 patients and 21 controls completed the questionnaire and were submitted to overnight polysomnography. The 8-item scores of the ESS-BR had an overall reliability coefficient (Cronbach's alpha) of 0.83, indicating a high degree of internal consistency. The total number of subjects in the groups was: 21 controls, 34 patients with snoring, 21 with insomnia and 59 with OSAS. The mean (±SD) ESS-BR score was 5.2 ± 3.0 for control subjects; 8.8 ± 3.4 for snoring patients; 5.3 ± 2.6 for those with insomnia; 13.5 ± 5.1 for those with OSAS. One-way ANOVA demonstrated significant differences in ESS-BR scores across the four diagnostic groups (p<0.001). Post hoc tests between paired groups showed that the ESS-BR scores for insomniacs did not differ from controls (p>0.05). Scores for OSAS and primary snorers were significantly higher than for controls (p<0.05). The ESSBR scores for OSAS were significantly higher than for primary snorers (p<0.05). Conclusions: Our data validate the ESS-BR for application to Brazilian Portuguese-speaking populations. No major cultural adaptations were necessary during the validation process. Despite relevant influences of language and cultural background, the ESS-BR can be a tool for clinical management and research. |
