目的︰翻譯並建立兒童及成人睡眠型態偏好量表的信、效度·方法︰299位兒童及成人樣本完成問卷信度施測後，以隨機取樣法，選取台北市三所國小之四、五、六年級和三所國中之一、二年級，每校每年級各隨機抽三個班級，共15班，全班學生及其父母為研究樣本進行問卷研究，最後得到的有效學生樣本為1547（98.4%）人（男︰811，女︰736）。結果︰兒童量表的Cronbach's 係數為0.68，各題得分與總分之積差相關係數為0.37-0.63（p<0.001），前後二次施測的內在等級相關（intraclass correlation）為0.75；成人量表的Cronbach's 值為0.81，各題得分與總分之積差相關係數為0.37-0.71（p<0.001），前後二次施測的內在等級相關為0.94。兩量表各分項目均具鑑別力。以四分位數分布，將量表總分小於等於前25%者歸類為下午型，大於等於後25%者為上午型，不論兒童或成人，上午型者較下午型者早睡早起、有較高的比例早上自動醒來、白天打瞌睡的情形較少。結論︰中文版兒童及成人睡眠型態偏好量表具有不錯的信、效度，可以清楚地找出不同睡眠型態偏好的人，適用於大樣本有關睡眠習慣研究。

　　　　　Objectives: This research assessed the validity and reliability of the Chinese version of the self-administered Morningnesss/Eveningness Scales (M/E Scale) for children and adults, respectively. Methods: The authors translated the 10-item M/E Scale for children and the 13-item M/E Scale for adults from the English version adapted by Caskardon. One hundred and nine sixth grade primary school students and 190 first grade junior high school students and their parents served the subjects for the reliability study. Sixty-eight among the 299 subjects received the test-retest reliability test during a 4-week period. Through stratified random sampling, fourth through sixth grade students from 3 primary schools and first and second grade students from 3 junior high schools in Taipei were selected. In each school, all students of 3 randomly chosen classes of each grade were selected as subjects. A total of 1547 subjects, 811 (52.4%) boys and 736 (47.6%) girl, were included in the study. The response rate was 98.4%. Results: The internal consistency Cronbach's values were 0.68 and 0.81 for the children's and adults' version, respectively. The item-total correlation coefficients were 0.37-0.63 and 0.37-0.71 for the children's and adults' version, respectively. The critical ratios were 5.15-12.26 and 4.29-16.54 for the children's and adults' version, respectively. The intraclass correlations were 0.75 and 0.94 for the children's and adults' version, respectively. Evening type and morning type were differentiated on the external criteria obtained with the 25-75 percentile split of the M/E Scale. Based on both versions, the morning groups reported earlier bedtimes on weekday and weekend nights, as well as earlier rising times on weekday and weekend mornings, and were more likely to wake spontaneously. The evening groups more frequently reported daytime napping. Conclusions: The two Chinese versions of the M/E Scale have adequate reliability and validity. They can successfully identify the distinct groups of phase preference.
