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

【目的】 应用贝莉婴幼儿发育量表-第3版(Bayley Scales of Infant and Toddler Development-Third Edition,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's α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。

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

【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(P<0.001).Cronbach’s α coefficient was 0.956~0.993.The inter-rater reliability was 0.906~0.950(P<0.001).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(P<0.001),but lower in adaptive behavior scale(P<0.001).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.
