Abstract

OBJECTIVE: The purposes of this study were 1) to re-examine effects obtained from previous research of a non-face-to-face behavioral intervention in poorer sleepers and 2) to examine the factors impacting on improvement of sleep. METHODS: The subjects were 178 poor sleepers who participated in an intervention for sleep improvement. The educational procedures comprised a minimal behavioral self-help package for one month that featured self- learning and self- monitoring of practical target habits for change. It was non face-to-face program conducted by only one member of staff. Subjects were asked to answer a questionnaire before and after the intervention. To reexamine the effects of this program found in our previous research, 9 sleep indices, sleep quality, and sleep-related behaviors were compared between before and after intervention. The sleep indices were total sleep time, sleep onset latency, sleep efficiency etc. Subjects were divided into an improvement group (n = 63) and a non-improvement group (n = 115) using a cutoff value for average change in sleep onset latency and sleep efficiency. After comparison of sleep and behavior between the two groups, logistic regression analysis was conducted to select parameters affecting improvement with this program. RESULTS: Total sleep time was significantly increased from 5.7 h to 6.1 h, sleep onset time decreased 18 minutes, and sleep efficiency improved 5.6 points. With 8 of 9 sleep-related behaviors, the proportion of subjects having an undesirable habit significantly decreased. The mean total number of desirable habit' changes was 2.63 in the improvement group and significantly higher than the 2.06 in the non-improvement group. Logistic regression analysis demonstrated that large sleep onset latency at baseline and beginning of regular exercise significantly affected the improvement of sleep in the subjects, after adjusting for all other parameters. CONCLUSION: The effects revealed by our previous research were reconfirmed. It is suggested that this program is more useful for persons having severe sleep onset difficulties, and regular exercise is particularly important in improvement of sleep. It is possible that even simple behavioral intervention is feasible with many subjects to improve sleep and related habits in poor sleepers.
