Harmonized/Polysomnography/Sleep Architecture
in
MSP variables
Harmonized by the NSRR team. Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep (i.e. total sleep time, TST), while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time (i.e. time in bed, TIB). Percentage of time in bed that was spent sleeping, or the ratio of total sleep time to total time in bed, expressed as a percentage. Source variable: :se:

Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep (i.e. total sleep time, TST), while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time (i.e. time in bed, TIB). [100*(total sleep time) / (total time in bed)]

CHAT variables
Conventionally, this variable would be called the end of time in bed (TIB). In this dataset, it concurs with the last epoch of sleep. Harmonized by the NSRR team. Source: :stlonp:

[(Total Sleep Time (TST)) / (time from sleep onset to morning waking)] * 100 (data can be inaccurate if scorer has not set sleep onset rule properly in compumedics software)

In this study, rest period (i.e. rest interval) is defined as in-bed period (i.e. time in bed, TIB), therefore the start time of rest period is in-bed time.
