Morningness-Eveningness Questionnaire (MEQ) developed by Horne & Ostberg (1976) was translated into Japanese, and then, MEQ and Life Habits Inventory were administered to approximately 1,500 university students. The distribution of MEQ scores was essentially normal, and the reliability of this questionnaire was high (r alpha = .702). Comparing among the morning, evening, and intermediate types, it was found that the morning type retired and arose significantly earlier than other types, although there was no significant differences in sleep length. Furthermore, there were significant differences between the morning and evening types in sleep latency, mood on arising, adequate amount of sleep, frequency and duration of nap, and number of staying awake all night per month. These results suggested that the evening type had more irregular sleep-waking habits than the morning type. Since the above results were obtained only from student population, further investigation on various populations is requested.
霍恩和奥斯特伯格（1976年）编制的晨型-夜型问卷（MEQ）被翻译成日语，然后，对大约1500名大学生进行了MEQ和生活习惯量表的测试。MEQ得分的分布基本呈正态分布，该问卷的信度较高（α系数=0.702）。比较晨型、夜型和中间型，发现晨型的就寝和起床时间明显早于其他类型，尽管睡眠时间没有显著差异。此外，晨型和夜型在入睡潜伏期、起床时的情绪、充足的睡眠时间、小睡的频率和时长以及每月彻夜未眠的次数方面存在显著差异。这些结果表明，夜型的睡眠-清醒习惯比晨型更不规律。由于上述结果仅来自学生群体，因此需要对不同人群进行进一步调查。
