Module 3: Assessment

Lesson 3

Standard assessment tools

• General medical/ psychiatric/ medication questionnaire (i.e., to identify comorbidity and medication use)
• Epworth Sleepiness Scale or other sleepiness assessment
• Two-week sleep log to identify sleep-wake times, general patterns, and day-to-day variability, including:
  • Bedtime
  • Sleep latency (SL: time to fall asleep following bedtime)
  • Number of awakenings and duration of each awakening
  • Wake after sleep onset (WASO: the sum of wake times from sleep onset to the final awakening)
  • Time in bed (TIB: time from bedtime to getting out of bed)
  • Total sleep time (TST: time in bed minus SL and minus WASO)
  • Sleep efficiency percent (SE equals TST divided by TIB times 100)
  • Nap times (frequency, times, durations) Reports of sleep quality, daytime impairment, medications, caffeine, and alcohol consumption for each 24-hour period.
