Test-retest reliability of the Epworth Sleepiness Scale in clinical trial settings.

ABSTRACT: The present analysis examined the test-retest reliability of the Epworth Sleepiness Scale in participants with excessive daytime sleepiness associated with narcolepsy or obstructive sleep apnea in three clinical trials. Intraclass correlation coefficient estimates for Epworth Sleepiness Scale scores from two solriamfetol 12-week placebo-controlled trials (one narcolepsy, one obstructive sleep apnea) and one long-term open-label extension trial (narcolepsy or obstructive sleep apnea) were calculated using postbaseline time-point pairs for the overall population in each trial, by treatment, and by primary obstructive sleep apnea therapy adherence. In the 12-week narcolepsy trial, intraclass correlation coefficients (95% confidence intervals) were 0.83 (0.79, 0.87) for weeks 4 and 8 (n = 199)
