Reliability of Sleep Measures
Abstract
The reliability of sleep measures was calculated over two nights (and within the nights) for twenty young adult males. Percent time in stages 1, 2, 3, and 4, percent movement time, number of movements, and number of stage changes were significantly correlated between subjects over nights. The percent REM time and REM cycle duration were not significantly correlated over nights. Within subjects, the length of the REM period had a significant negative correlation with the length of the preceding NREM period but not with the following NREM period. These data raise questions as to the use of the standard sleep measures as a reliable human traits in young male adults.
