Abstract

Seven women and 11 men, mean age 30.1 years, kept a sleep log for 5-7 days, and their wrist activity was monitored each minute. Sleep-wake state in the sleep log and actigraphic sleep-wake state were compared, and the sensitivity and specificity of the sleep log were calculated for each subject. The ratio of agreement between these two parameters was computed for each subject. The sensitivity and specificity of the sleep log were 72.73- 97.56% (mean 86.71%) and 92.85-99.68% (mean 97.04%), respectively. The agreement ratio was 87.30-97.85% (93.48%), but 1-h agreement ratios from midnight dropped during the sleep onset period.
