目的 验证中国婴儿睡眠状况评估量表(ISAS)的信度效度,建立全国常模、睡眠不良和睡眠异常的界值。方法 采用多阶段随机抽样,选取我国7省14市城乡地区的5 855例婴儿(其中0～3个月2 943例,4～11个月2 912例)看护人进行调查。采用内部一致性信度、分半信度和验证性因子分析对量表的信度效度进行验证,制定百分位常模,分别以超过P85、P95作为量表总分判断睡眠不良、睡眠异常的界值。结果 ISAS(0～3个月)和ISAS(4～11个月)Cronbach's α系数分别为0.68、0.69,分半信度为0.78、0.75,因子结构模型稳定,具有较好的信度和效度。建立了ISAS(0～3个月)的年龄常模以及ISAS(4～11个月)分性别的年龄常模。两个量表总分的睡眠不良界值分别是31、32,睡眠异常界值分别是34、35。结论 两个量表具有稳定的信度和效度,构建的常模和界值可用于量化评估婴儿睡眠状况,为ISAS的推广和应用提供量化依据。
Abstract
Objective To verify the reliability and validity of the Chinese Infants Sleep Assessment Scales (ISAS), and to establish national norms and cut-off scores of poor sleep and abnormal sleep. Methods Using multistage random sampling, an investigation was conducted among 5 855 urban and rural infants' caregivers (including 2 943 infants aged 0 to 3 months and 2 912 infants aged 4 to 11 months) from 14 cities in 7 provinces. The internal consistency reliability, split-half reliability and confirmatory factor analysis were used to verify the reliability and validity of the scales. Then the percentile norms were established, and the total ISAS scores exceeding P85 and P95 were used as the cut-offs for identifying poor sleep and abnormal sleep. Results The Cronbach's α coefficients of ISAS (for infants aged 0 to 3 months) and ISAS (for infants aged 4 to 11 months) were 0.68 and 0.69, the split-half reliability were 0.78 and 0.75, respectively. The factor structure models were stable, which showed good reliability and validity. The age norm of ISAS (for infants aged 0 to 3 months) and the gender-specific age norm of ISAS (for infants aged 4 to 11 months) were established. The cut-off values of ISAS score for poor sleep were 31 and 32 in the two scales, respectively, which were 34 and 35 for abnormal sleep, respectively. Conclusions ISAS (for infants aged 0 to 3 months) and ISAS (for infants aged 4 to 11 months) have stable reliability and validity. Their norms and cut-offs can be used to quantitatively evaluate infants' sleep, in order to provide an quantitative basis for their promotion and application.
