Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study parameters are objective outcomes related to sleep-wake and rest-activity rhythms of the participants assessed by Actigraphy. Outcomes related to the sleep-wake cycle are: 1. total sleep time 2. number and length of wake bouts during the night 3. sleep efficiency (ratio of total sleep time and time spent in bed). Outcomes according to rest-activity rhythm are: 1. acrophase (time of peak activity) 2. amplitude 3. mesor (mean) of the 24 hour activity curve 4. relative amplitude (RA; difference between 10 most active hours and 5 least active hours) 5. intradaily variability (IV; change in activity level from hour to hour) 6. interdaily stability (IS; measures strength of activity rhythm to environmental zeitgebers, based on chi square periodogram). | — |
