Validated a novel scale to evaluate both “active” sleepiness and “passive” sleepiness using questions that reflect modern life.

This study compared the Situational Sleepiness Scale (SSS) to the Epworth Sleepiness Scale (ESS), which is the current standard to assess sleepiness. The scores were highly correlated (rs=0.72) in a sample of 22 Stanford Sleep Medicine patients and 34 healthy controls. We believe the SSS is a can provide more nuanced picture regarding patient’s overall sleepiness, especially while driving and should be evaluated in a wider population.
