The mean change in the Patient-Reported Outcomes Measurement Information System Sleep Disturbance-Short Form 8b (PROMIS SD SF 8b) total T-score from baseline to Week 12 is a key secondary endpoint in OASIS 1 and OASIS 2.3
PROMIS SD SF 8b assesses the self-reported perception of sleep disturbance over the past 7 days3
Includes 8 items3*:
- Restless sleep
 - Satisfaction with sleep
 - Refreshing sleep
 
- Difficulties falling asleep
 - Staying asleep
 - Getting to sleep
 
- Amount of sleep
 - Sleep quality
 
*Items were scored on a 5-point Likert scale, and the 8 single item scores were summed to yield total raw scores (range, 8-40), which were converted to total T-scores for analysis of the key secondary endpoint (range, 28.9-76.5).3
Higher scores indicate more disturbed sleep.3
