    Sleep health is postulated as a multi-dimensional construct comprised of sleepiness/alertness, timing, duration, efficiency, and satisfaction. New questionnaires for its measurement have been proposed. We performed secondary data analyses and analyzed responses on a widely used, well-established sleep questionnaire to determine whether the construct might be detectable with an existing questionnaire. Healthy men (nā€‰=ā€‰7604) aged 55-75 completed the six-item Medical Outcomes Study Sleep Questionnaire (MOSSQ) at baseline in a large, randomized clinical trial [the Reduction by Dutasteride of Prostate Cancer Events (REDUCE) trial). Two components clearly emerged from a Principal Components Analysis, suggesting that both sleep disturbance and sleep satisfaction are differentiated by the MOSSQ. Selected elements of sleep health are accessible with relatively few questionnaire items. Widespread previous usage of the MOSSQ in both descriptive and interventional research suggests that many previously collected databases could address at least two components of this construct.]
