    • Abstract:
      BackgroundExcessive daytime sleepiness (EDS) is an indicator of sleep disordered breathing (SDB) and the Epworth sleepiness scale (ESS) is a popular instrument to evaluate EDS subjectively. Although translated and validated in different languages including Hindi, but there has been no available and validated Bengali version of ESS so far. MethodsThe original English version of ESS has been translated in Bengali and thereafter cross translated in English with proper human resources. The accepted Bengali version was then given to 30 patients of obstructive sleep apnea (OSA) and 30 normal individuals (based on polysomnographic diagnosis) along with the original English version to respond. The mean score of responses for both the versions were thereafter compared. ResultsThere was no significant difference on statistical analysis between the means obtained from using the two versions of ESS. ConclusionThe Bengali version of ESS is thus found valid and reliable and can be successfully used.
