The MOS Sleep Scale is a patient-reported, non-disease-specific instrument for evaluating sleep outcomes. Consisting of 12 items, the MOS Sleep Scale measures subjective experiences of sleep across several different domains. Ten of the scale’s 12 items are scored using a six-point response scale, one item uses a five-point Likert scale, and sleep quantity is an open-ended question recording the actual number of hours slept. All domains except sleep quantity are recalibrated on a 0–100 scale that represents the percentage of a particular sleep domain; sleep quantity is recorded as 0–24 h. Higher scores for the domains of sleep disturbance, somnolence and the sleep indices indicate worse sleep problems, whereas lower scores for sleep quantity and sleep adequacy indicate worse sleep problems.
