Sleep medicine
-
Sleep is an active and highly organized biological process that is an important component of life. Self-report measures of sleep provide information that can be useful for characterizing the quality of sleep in subgroups of the population. A 12-item self-report sleep measure, the Medical Outcomes Study Sleep measure, was developed and evaluated previously in a sample of 3445 individuals with chronic illness. ⋯ This study provides further support for the reliability and validity of the MOS Sleep measure. The instrument can be used to assess important aspects of sleep perceived by adults in the general population or participating in clinical studies.
