贝莉婴幼儿发育量表-第三版评价上海市婴幼儿发育水平的应用初探

Research on the applicability of Bayley Scales of Infant and Toddler Development-Third Edition to assess the development of infants and toddlers in Shanghai

【目的】应用贝莉婴幼儿发育量表-第3版（Bayley Scales of Infant and Toddler Development-Third Edi-tion,Bayley-Ⅲ）评价上海市婴幼儿发育,并分析该量表信度和效度,以探讨其在中国应用的可行性。【方法】选取0~42月正常婴幼儿457例行Bayley-Ⅲ测试,其中33例测试时由2名专业人员同时评分,24例1周后进行重测,34例在同一天应用Bayley-Ⅲ和Gesell发育量表测试。【结果】1）Bayley-Ⅲ的重测信度为0.711~0.831（P均〈0.001）,Cronbach＇sα系数为0.956~0.993,评分者间信度为0.906~0.950（P均〈0.001）。2）Bayley-Ⅲ动作合成分数与Gesell发育量表的动作能发育商（developmental quotient,DQ）相关系数为0.367（P〈0.05）,认知合成分数与Gesell发育量表的应物能DQ相关系数为0.164（P〉0.05）,语言合成分数与Gesell发育量表的言语能DQ相关系数为0.119（P〉0.05）。3）457例正常婴幼儿Bayley-Ⅲ认知、语言和动作子量表得分均高于美国常模参考值（P均〈0.001）,适应性行为量表得分低于美国常模参考值（P〈0.001）。4）女孩在认知、语言和社会情感量表中得分高于男孩（P均〈0.05）。【结论】中美儿童发育存在一定差异,但Bayley-Ⅲ信度良好,应用于中国婴幼儿发育状况评估具有可行性。

【Objective】 To explore the applicability of Bayley Scales of Infant and Toddler Development-Third Edition（Bayley-Ⅲ） to assess the development of infants and toddlers in Shanghai and to analyze the reliability and validity. 【Methods】 457 normal infants and toddlers aged 0~42 months were tested with Bayley-Ⅲ.Among those children,33 were scored by two examiners during test,24 were retested after a week and 34 were tested with both Bayley-Ⅲ and Gesell on the same day. 【Results】 1）The test-retest reliability was 0.711~0.831（P0.001）.Cronbach＇s α coefficient was 0.956~0.993.The inter-rater reliability was 0.906~0.950（P0.001）.2）There was low correlation between three kinds of composite score in Bayley-Ⅲ and applicability developmental quotient（DQ） in Gesell（r=0.119~0.367）.3） The mean score of 457 normal infants and toddlers was higher than the norm reference score of American in cognitive,language and motor subscales（P0.001）,but lower in adaptive behavior scale（P0.001）.4） Girls scored higher than boys in cognitive,language and social-emotional subscales. 【Conclusions】 There are some differences in development between Chinese and American children,but Bayley-Ⅲ shows good reliability.It is feasible to assess the development of infants and toddlers in china.
