and use these results to provide a number of measures
from the period. These are described below:
 Time in bed: The total elapsed time between the ‘Lights
Out’ and ‘Got Up’ times.
 Assumed sleep: The total elapsed time between the ‘Fell
Asleep’ and ‘Woke Up’ times.
 Actual sleep time: The total time spent in sleep according
to the epoch-by-epoch wake/sleep categorisation.
 Actual sleep (%): Actual sleep time expressed as a
percentage of the assumed sleep time.
 Actual wake time: The total time spent in wake according
to the epoch-by-epoch wake/sleep categorisation.
 Actual wake (%): Actual wake time expressed as a
percentage of the assumed sleep time.
 Sleep efficiency (%): Actual sleep time expressed as a
percentage of time in bed.
 Sleep latency: The time between ‘Lights Out’ and ‘Fell
Asleep’.
 Sleep bouts: The number of contiguous sections
categorised as sleep in the epoch-by-epoch wake/sleep
categorisation.
 Wake bouts: The number of contiguous sections
categorised as wake in the epoch-by-epoch wake/sleep
categorisation.
 Mean sleep bout: The average length of each of the sleep
bouts.
 Mean wake bout: The average length of each of the wake
bouts.
 Immobile mins: The total time categorised as Immobile in
the epoch-by-epoch mobile/immobile categorisation.
 Immobile time (%): The immobile time expressed as a
percentage of the assumed sleep time.
 Mobile mins: The total time categorised as mobile in the
epoch-by-epoch mobile/immobile categorisation.
 Mobile time (%): The mobile time expressed as a
percentage of the assumed sleep time.
 Immobile bouts: The number of contiguous sections
categorised as immobile in the epoch-by-epoch
mobile/immobile categorisation.
 Mean immobile bout: The average length of each of the
immobile bouts.
 Immobile bouts <=1min: The number of immobile bouts
which were less than or equal to one minute in length.
 Immobile bouts <=1min (%): The number of immobile
bouts less than or equal to one minute expressed as a
percentage of the total number of immobile bouts.
