Abstract: Objective To develop Chinese Infants Sleep Assessment Scales (ISAS) suitable for Chinese infants under the age of 1 year old, and to evaluate the reliability, validity and feasibility of the scales. Methods The scale was divided into two ages, 0—3 months and 4—11 months, according to the infants' sleep development characteristics.Firstly, an item pool with 4 dimensions of sleep rhythm, bedtime arrangement, night wakings and sleep disordered breathing was constructed.Then, the scales were compiled and evaluated through preliminary screening, modification, item analysis, validity analysis, reliability analysis and confirmatory factor analysis. Results The ISAS (0—3 months) and ISAS (4-11 months) both had 14 items, including 4 factors of sleep rhythm, bedtime arrangement, night wakings and sleep disordered breathing with total variance explained of 56.61% and 55.02%, respectively.The items of the two scales were slightly different.The item-level content validity of all items in both scales ranged from 0.83 to 1.00.The two scales were positively correlated with Brief Infant Sleep Questionnaires (BISQ) in terms of sleep latency, number of night wakings and sleep duration, with correlation coefficients of 0.31,0.41,0.39 and 0.32,0.66 and 0.38, respectively.There were statistically significant differences between community sample and clinical sample in the total scores of the two scales and most of the factors (except the sleep disordered breathing factors of the 0-3 months) (P<0.05).The Cronbach's α coefficients of the two scales were 0.681 and 0.673, and the test-retest reliability were 0.75 and 0.74. Conclusion The two scales have relatively stable factor structures and good reliability and validity, which can be used for early screening of infants' sleep problems.

摘要： 目的 编制适用于我国1岁以下婴儿的睡眠状况评估量表,评价其信度、效度和可行性。方法 根据婴儿睡眠发育年龄特点,将量表划分为0～3个月和4～11个月两个年龄段。首先按照量表编制框架的睡眠节律、入睡行为、夜醒、睡眠呼吸4个维度建立条目池,然后依次通过条目初筛、修改、项目分析、效度分析、信度分析和验证性因子分析完成量表的编制和评价。结果 婴儿睡眠状况评估量表(0～3个月)和婴儿睡眠状况评估量表(4～11个月)均包含睡眠节律、入睡行为、夜醒和睡眠呼吸4个因子14个条目,条目内容略有不同,累积解释总变异量分别为56.61%、55.02%。两个量表所有条目的内容效度指数介于0.83～1.00。两个量表在入睡潜伏期、夜醒次数、睡眠时间3个条目与简明婴儿睡眠问卷(BISQ)呈正相关,相关系数分别为0.31、0.41、0.39和0.32、0.66、0.38。社区婴儿与门诊婴儿在两个量表总分以及绝大部分因子(除0～3个月量表睡眠呼吸因子)上的差异均有统计学意义(P＜0.05)。两个量表的Cronbach's α系数为0.681、0.673,重测信度分别为0.75和0.74。结论 两个量表具有比较稳定的因子结构及较好的信效度,可以用于婴儿睡眠问题的早期筛查。
