This study was performed to standardize the Korean version of the SMH sleep questionnaire and to identify the age differences in sleep patterns. The author translated 'The St. Mary's(SMH) sleep questionnaire'(Ellis et al. 1981) into Korean and applied it to the Korean subjects. For standardization, 101 subjects were devided into two groups, 58 normal adults group and 43 psychiatric in-patients group. They completed the sleep questionnaire twice a day, immediately after waking up in the morning and then about 4 hours later. Test-retest correlation coefficients were calculated using SPSS/PC(???). For identifying the age differences of sleep patterns, the sleep questionnaire was applied to the 3 age groups, puberty group aged 13-14, young adult group aged 20-25, and middle age group aged 38-42, ANOVA was performed using SPSS/PC(???). The results were as follows : 1) This sleep questionnaire is found to be a reliable tool to find out general sleep patterns not only in normal persons but also in psychiatric patients in Korea. 2) Characteristics of sleep patterns among 3 age groups are : (1) Puberty group were still sleepy when woke up, and had little problem in getting to sleep with short sleep latency. (2) Young adult group were late in settling down for the night, falling asleep, waking up and getting up with long midday nap time. 3) Middle age group woke up frequently during sleep, had short total sleep time, and were troubled by waking early and being unable to get off to sleep again.

To identify the effect of total sleep deprivation on sleep structures, polysomnography was performed for 8 healthy young adults. The subjects were young adults, ranging in age from 21 years to 26 years, with no past or present histories of significant medical, neurological, or psychiatric illness as well as no current major sleep disturbances or parasomnias, After one adaptation night, each subject was recorded polysomnography in the sleep laboratory. Sleep records were analyzed according to the criteria of Rechtschaffen and Kales every 20 seconds, and tried paired-t-test. The results were summarized as follows. 1. After on night of total sleep deprivation, compared with the baseline WASO was significantly decreased in the first recovery night, and SWS and REM sleep were significantly increased in the first recovery night. 2. Compared with the baseline, the relative value(%) of REM sleep was significantly increased in the first recovery night. 3. Compared with the baseline, TST was significantly increased in the first recovery night, and sleep latency and REM latency were significantly decreased in the first recovery night. According to the above results we could identify the effects of total sleep deprivation on sleep structure in normal young adults.

To identify the effects of partial sleep deprivation on the sleep structure, the authors performed polysomnographic study for 9 healthy young adults. The subjects were college students, ranging in age from 20 to 25 years, without personal past or present histories of medical, neurological, or psychiatric illness and suffering from current sleep disturbance or parasomomnias. Sleep records were analyzed according to the criteria of Rechtschaffen and Kales' manual and tried paired t-test. The results were summarized as follows. 1. As for sleep parameters, total sleep time(TST), REM latency and REM duration were not changed significantly during deprivation period and recovery period compared with baseline. Sleep efficiency increased significantly during deprivation period and recovery period compaired with baseline, and sleep latency and WASO were shortened significantly during deprivation period and recovery period compared with baseline. 2. As for sleep structure, 1) The absolute value(minutes) of stage 1 decreased significantly during deprivation period and first recovery night compared with baseline, and the relative value(percentage) of stage 1 decreased significantly during deprivation period and recovery period compared with baseline. 2) The absolute value(minutes) of stage 2 decreased significantly during deprivation period compared with baseline, and the relative value(percentage) of stage 2 decreased significantly during deprivation period and first recovery night compared with baseline. 3) The absolute value(minutes) of slow wave sleep were not changed significantly during deprivation period and recovery period compared with baseline, and the relative value(percentage) of slow wave sleep increased significantly during recovery period compared with baseline. 4) The absolute value(minutes) of REM sleep decreased significantly during deprivation period compared with baseline, and the relative value(percentage) of REM sleep decreased significantly in the first deprivation night but, were not changed significantly during recovery period compared with baseline.
