In this study, we examined the relationship between sleep log and subjective sleep quality.
Thirty five undergraduate students (male: 12, female: 23) completed sleep log for two weeks and the item of subjective sleep quality in The Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). Sleep log measures bedtime, arise time, and subjective sleep time. We added the item of easiness of awakening, soundness of sleep, and daytime sleepiness, as the variables of subjective sleep quality.
In order to investigate the relationship between sleep log and the item of subjective sleep quality, we calculated Spearman's rank correlation coefficient. As a result, subjective sleep time significantly correlated with easiness of awakening(r=.44), soundness of sleep(r=.40), daytime sleepiness(r=.45). Actual sleep time did not correlate sleep log and subjective sleep quality.
The result of this study showed subjective sleep time might relate to subjective sleep quality.
