Abstract:

Objective　To work out sleep questionnaire scale which is suitable for investigating the sleep disorder status in snoring chilren in order to apply to clinical work. Methods　A total of 1017 children with over 2 months of snoring or mouth breathing aged 3 to 14 years were selected，and according to the scale formulation specifications，the item pool was formulated by combining with the theoretical knowledge of common sleep disorders in children and consulting a large number of literature. Then the primary scale was formed after the expert group modified or deleted some items. Forty items were selected as the final scale by using factor analysis method and then its reliability and validity was evaluated . Results    The sleep questionnaire scale in snoring children was composed of five dimensions，40 items. In the aspect of reliability，the total Cronbach；alpha coefficient of the scale was 0.7373. The Cronbach’α coefficient of other dimensions was 0.5789 in snoring symptoms at night，0.6769 in symptoms associated with sleep and related diseases，0.7983 in behavioral symptoms，0.6038 in daytime sleepiness symptoms and 0.8354 in others’ evaluation on childrens’ drowsiness，respectively. In the aspect of structure validity，confirmatory factor analysis showed that the standardized coefficient load in 60% of entries was greater than 0.4，which was acceptable. Conclusion    Sleep questionnaire scale in snoring children has good reliability and acceptable validity.

摘要：

目的    研究制订适合鼾症儿童睡眠障碍状况调查的量表，应用于临床。方法　选择2015年1月至12月就诊于首都医科大学附属北京儿童医院睡眠中心的存在夜间打鼾或张口呼吸症状持续2个月及以上的3～14岁儿童1017例，根据量表制订规范，结合儿童常见睡眠障碍理论知识，查阅文献后形成条目池，再由专家组对条目池进行修正及删除，形成初量表。采用因子分析法筛选出40个条目作为最终量表，再进行信度、效度考核。结果　鼾症儿童睡眠呼吸障碍量表由5个维度、40个条目组成。信度方面，本量表总克朗巴赫系数（Cronbach’α coefficient）为0.7373，其余各维度的克朗巴赫系数分别为夜间打鼾相关症状0.5789、睡眠伴随症状及相关疾病情况0.6769、日间嗜睡相关症状0.6038、行为相关症状0.7983、他人对儿童嗜睡的评价0.8354。结构效度方面，验证性因子分析显示60%的条目其标准化系数载荷＞0.4，可接受。结论　鼾症儿童睡眠障碍量表信度较好，效度可接受。
