In summary, the ESS seems to measure only one factor and has a high degree of internal consistency. Validity testing does not unequivocally support the use of the ESS as a measure of daytime sleepiness or sleep propensity. However, ESS scores do relate to important clinical outcomes such as road traffic accidents and health-related quality of life. Serious reservations exist regarding the reliability and responsiveness of the ESS, given the lack of test-retest data in patients with OSA. Due to the limitations posed by the lack of adequate construct validity and responsiveness data, use of the ESS as a diagnostic tool and as a clinical outcome measure may not be justified at the present time. Future research should explore these issues with methodologic and statistical rigour.
