Description
Objectives
We validated actigraphy for detecting sleep and wakefulness versus polysomnography (PSG).
Design
Actigraphy and polysomnography were simultaneously collected during sleep laboratory admissions. All studies involved 8.5 h time in bed, except for sleep restriction studies. Epochs (30-sec; n = 232,849) were characterized for sensitivity (actigraphy = sleep when PSG = sleep), specificity (actigraphy = wake when PSG = wake), and accuracy (total proportion correct); the amount of wakefulness after sleep onset (WASO) was also assessed. A generalized estimating equation (GEE) model included age, gender, insomnia diagnosis, and daytime/nighttime sleep timing factors.
Setting
Controlled sleep laboratory conditions.
Participants
Young and older adults, healthy or chronic primary insomniac (PI) patients, and daytime …
