For the purpose of standardizing “the Morningness-E veningness Questionnaire” designed by Home and Stberg and of investigating the distribution of the sleep pattern and the differences between sleep pattern and sleep parameters according to age and sex in Korean, the authors translated the Morningness-Eveningness Questionnaire into korean and applied it to 557 Korean students. The results were as follows : 1) The test-retest reliability coefficient(r) of this questionnaire was r= 0.81 and the Cron bach ’s alpha was 0.65，so this tool can be applied reliably for differentiating the M -E sleep pattern of Korean. 2) As for sleep pattern, ① In total subjects, the most frequent pattern was intermediate type and evening type was more frequent than morning type. ② The most frequent pattern was intermediate type in all grades, evening type was more frequent in the group of middle school and morning type was more frequent in the group of high school and college.
