【目的】将国际通用的贝利婴幼儿发展量表(Bayley Scales of Infant Development,BSID)在陕西关中农村进行标准化,制定出陕西关中农村BSID的常模。【方法】按照整群抽样原则随机抽取陕西关中地区10个县区,共计430名健康婴幼儿。用BSID测评智力发展指数(mental development index,MDI)和运动发展指数(psychomotor develop-ment index,PDI)。【结果】430名小儿的MDI和PDI呈现正态分布,说明常模的样本代表性好。测试者间信度智力与运动量表条目的相关系数为0.94和0.96,P值均<0.01。重测信度相关系数为智力量表为0.88及0.79,运动量表为0.92及0.86。BSID量表和盖塞尔(Gesell)发育量表得分之间呈中度相关(r=0.65,P<0.01)。城市版量表内容基本适合陕西省关中农村的婴幼儿,部分条目的年龄定位发生了变化,表现为智力量表163个条目有30(18%)个条目的次序后移。运动量表81个条目中有35个(43%)提前,有15个(17%)推后。【结论】修订后的量表与Gesell量表具有较好的相关性。陕西版的BSID适合于在陕西省2~30月农村婴幼儿中应用。
【Objective】 To standardize the internationally-accepted Bayley Scales of Infant Development (BSID) in the rural areas of Guanzhong in Shaanxi Province, and to develop a norm of BSIDs in rural areas in central Shaanxi Province. [Method] According to the principle of cluster sampling, 10 counties and districts in Guanzhong area of Shaanxi Province were selected randomly, a total of 430 healthy infants. The BSID was used to assess the mental development index (MDI) and the psychomotor develop ment index (PDI). 【Results】 The results showed that there was a normal distribution of MDI and PDI in 430 children. The correlation coefficient between the interpersonal reliability intelligence and the physical activity scale items was 0.94 and 0.96, P <0.01. The test-retest reliability correlation coefficients were 0.88 and 0.79 for the mental scale and 0.92 and 0.86 for the exercise scale. There was a moderate correlation between the BSID scale and the Gesell Scale (r = 0.65, P <0.01). The contents of the city version basically fit the infants and toddlers in the rural areas of Guanzhong in Shaanxi Province. The age positioning of some of the items has changed as the order of 30 (18%) entries of the 163 items of the intelligence scale has been shifted backwards. Thirty-five (43%) of the 81 entries in the athletic scores advance, and 15 (17%) postponed. 【Conclusion】 The revised scale has a good correlation with Gesell scale. The Shaanxi version of BSID is suitable for application in rural infants from February to September in Shaanxi Province.
