Total duration of sleep in stage 3/4 sleep from type I polysomnography

mnstg34p under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables

Total time scored as stage 3/4, rounded to nearest minute (use calculated variable - sleep wake studies screened out)

REM Sleep Latency: the interval between the first sleep epoch and REM sleep including wake from type I polysomnography

remlaip under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables

Total time from beginning of sleep to first epoch of rapid eye movement sleep (REM) (data can be inaccurate if scorer has not set sleep onset rule properly in compumedics software)

Wake After Sleep Onset: the total duration between sleep onset and lights-on/out-bed time while being awake from type I polysomnography

waso under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables

Total amount of time spent awake after going to sleep [(time in bed) - (sleep latency) - (Total Sleep Time (TST))]

Average number of wake intervals over nighttime periods

avgnwakeintervals_act_night under Sleep Monitoring/Actigraphy in SHINE variables

Variable sourced from actigraphy data

Average total wake time in the sleep periods across all rest intervals at nighttime periods

avgwaso_act_night under Sleep Monitoring/Actigraphy in SHINE variables

Variable sourced from actigraphy data

Coefficient of variation of total wake time in the sleep periods across all rest intervals at nighttime periods

covwaso_act_night under Sleep Monitoring/Actigraphy in SHINE variables

Variable sourced from actigraphy data

Standard deviation of total wake time in the sleep periods across all rest intervals at nighttime periods

stdwaso_act_night under Sleep Monitoring/Actigraphy in SHINE variables

Variable sourced from actigraphy data

Average number of wake intervals over nighttime periods

Variable sourced from sleep diaries

It is hard to wake the child up in the morning

sleepdisorder13_mom under Sleep Questionnaires/Sleep Disturbance in SHINE variables

Study scored sleep/wake rather than with full sleep staging if there is not sufficient quality on EEG lead. Studies scored as sleep wake have all sleep stages scored using a default of Stage 2 and no arousals are scored.
