To develop, standardize, and partly validate a developmental scale for toddlers (age, 1.6 to 3 years) attending anganwadis in India.
After the development of the 12-item Developmental Assessment Tool for Anganwadis (DATA), its internal consistency, face validity, content validity and construct validity were studied in 100 toddlers in anganwadis and were found to be appropriate. A total of 429 toddlers with a mean (SD) age of 30.9(5.2) months from 36 randomly selected anganwadis were recruited for its standardization. Raw scores were converted to standardized T-scores. Scoring pattern for domains and aggregate developmental scores were formulated.
Except for one item in the original scale, all the items were endorsed by parents suggesting a good content validity. Cronbachs a of 0.86 suggested a high internal consistency. Factor analysis replicated the 2 factor structure explaining 56 %of variance. An aggregated developmental score based on the standardized T-scores demonstrated that a DATA score between 33 and 28 suggested at risk for developing developmental delays. A score of 27 suggested already delayed milestones. A score of 27 to 16 suggested a mild delay, a score of 15 to 5 suggested a moderate delay and 4 suggested a severe delay in development.
DATA is a brief, simple and psychometrically sound measure for use in anganwadis for identifying toddlers at risk or with developmental delays. Differentially identifying toddlers at risk or with developmental delay helps in referring them for appropriate interventions.
开发、规范并部分验证一种适用于印度安格瓦迪中心1.6至3岁幼儿的发育量表。
在开发出12项安格瓦迪中心发育评估工具（DATA）后，对100名安格瓦迪中心的幼儿进行了内部一致性、表面效度、内容效度和结构效度研究，结果显示该量表较为合适。从36个随机选取的安格瓦迪中心招募了429名平均（标准差）年龄为30.9（5.2）个月的幼儿进行标准化研究。原始分数被转换为标准化T分数。制定了各领域的评分模式和总体发育分数。
除原始量表中的一项外，所有项目均得到家长认可，表明内容效度良好。克朗巴哈α系数为0.86，表明内部一致性较高。因子分析重现了2因素结构，解释了56%的方差。基于标准化T分数的总体发育分数显示，DATA分数在33至28之间表明有发育迟缓的风险。分数为27表明发育里程碑已经延迟。分数在27至16之间表明轻度延迟，分数在15至5之间表明中度延迟，分数为4表明严重发育延迟。
DATA是一种简短、简单且心理测量学上合理的测量工具，可用于安格瓦迪中心识别有风险或发育迟缓的幼儿。区分识别有风险或发育迟缓的幼儿有助于将他们转介接受适当干预。
