Abstract

Abstract: Objective　To translate the latest 11-item Circadian Type Inventory (CTI), and to verify its reliability and validity among undergraduates in medical universities. Methods　The Chinese version of CTI (C-CTI) was formed in the light of the modified Brislin translation model. A total of 308 undergraduates from Shanghai University of Traditional Chinese Medicine (sample 1) and 224 undergraduates from Xinxiang Medical University (sample 2) were selected for investigation by the convenient sampling between January and June 2018, and the reliability and validity of the C-CTI were tested. ① The critical ratio method and correlation analysis method were used to test the identity and homogeneity of the items; ② the expert consultation was used to test the content validity of the C-CTI; ③ the reliability of the C-CTI was tested by Cronbach coefficient, split reliability, and retest reliability. Independent sample t test was used for the measurement data. Pearson correlation analysis was used for correlation analysis. Results　In the sample 1, there were 76 males and 207 females, 5 unknown cases, with an average age of 20.45 years old; in the sample 2, there were 27 males and 197 females, with an average age of 19.80 years old. The C-CTI included 11 items and 2 dimensions. The total variance contribution rate was 48.109%, and the Cronbach's α coefficients of circadian rhythm stability and amplitude were 0.817 and 0.654. The range of item-level content validity index (I-CVI) was from 0.83 to 1.00, the average of scale-level content validity index (S-CVI/Ave) was 0.95, and each item was related to the overall score (r=0.265-0.684, all P<0.001). Conclusion　The C-CTI is suitable and robust enough for evaluating the circadian rhythm types among medical students.

摘要： 目的　对最新的11条目昼夜节律类型量表（Circadian Type Inventory， CTI）进行汉化及信效度检验。方法　采用改良后的Brislin翻译模型进行汉化；选择2018年1月至6月通过方便抽样法选取上海中医药大学各专业本科生308名（样本1）及新乡医学院本科生224名（样本2）进行调查，评估中文版量表的信效度。①使用临界比率值法和相关分析法来检验条目的鉴别度和同质性；②使用专家咨询法检验量表的内容效度；③量表的信度采用克朗巴赫系数、折半信度和重测信度检验。计量资料采用独立样本t检验；相关分析法采用Pearson相关性分析。结果　308名学生（样本1）中，有效问卷288份，其中男76名，女207名，缺失5名，平均年龄20.45岁；224名学生（样本2）中，男27名，女197名，平均年龄19.80岁。中文版量表共有11个条目，2个维度，累计方差贡献率为48.109%，昼夜节律稳定性的Cronbach's α系数为0.817，幅度维度的Cronbach's α系数为0.654。条目水平的内容效度指数为0.83～1.00，量表水平的内容效度指数为0.95，各条目与量表总分相关系数为0.265～0.684（均P<0.001）。结论　汉化的CTI在医学生人群中具有良好的信度和效度。
