Time of Day Sleepiness Scale (TODSS)
Constructed using items taken from the Epworth Sleepiness Scale (ESS; Chap. 29), the ToDSS was designed to collect subjective assessments of sleepiness for three different times of day: morning, afternoon, and evening. The scale allows clinicians and researchers to assess daytime sleepiness across a variety of situations at several different points in time. While still a new instrument, the ToDSS may prove useful for those who need an efficient measure of changes in daytime sleepiness throughout the day.
