In developing countries, it is often important to have measures of development in children under 3 years of age in large-scale surveys or evaluations of nutrition and stimulation programs. However, there is a lack of suitable instruments with established validity.
To develop a language test for children aged 12 to 18 months based on mothers' report, suitable for use in large-scale surveys, and examine its concurrent and predictive validity. To determine whether the test is sensitive to home stimulation and nutritional status and compare the test with the Bayley Scales of Infant Development (BSID).
A subsample of participants in a large, prospective cohort study in rural Bangladesh (MINIMat) was selected for a study of child development (n = 2,852). A total of 2,418 participants were interviewed concerning their children's expressive and receptive vocabulary, and children were tested using the BSID.
The language test had reasonable short- and long-term reliability between 12 and 18 months (r = 0.50) and concurrent validity with the Bayley Mental Development Index (MDI) (r = 0.32 language comprehension to 0.41 language expression). Its predictive validity with IQ at age 5 years was similar to that of the Bayley MDI (r = 0.37 to 0.41 for language and r = 0.37 for MDI). Child language was independently associated with postnatal growth, stimulation in the home, gestational age, and socioeconomic status, and a similar set of variables predicted the Bayley MDI.
The language test was reliable, had acceptable concurrent and predictive validity, and was sensitive to environmental and child characteristics. Mothers' reports of language could be useful in large-scale programs.
在发展中国家，在大规模调查或营养与刺激项目评估中，获取3岁以下儿童的发育指标通常很重要。然而，缺乏具有既定效度的合适工具。
基于母亲报告，为12至18个月大的儿童开发一种语言测试，适用于大规模调查，并检验其同时效度和预测效度。确定该测试对家庭刺激和营养状况是否敏感，并将该测试与贝利婴儿发育量表（BSID）进行比较。
从孟加拉国农村的一项大型前瞻性队列研究（MINIMat）的参与者子样本中选取进行儿童发育研究（n = 2852）。共对2418名参与者就其孩子的表达性和接受性词汇进行了访谈，并使用BSID对儿童进行了测试。
该语言测试在12至18个月之间具有合理的短期和长期信度（r = 0.50），与贝利智力发育指数（MDI）具有同时效度（语言理解r = 0.32至语言表达r = 0.41）。其对5岁时智商的预测效度与贝利MDI相似（语言r = 0.37至0.41，MDI r = 0.37）。儿童语言与出生后生长、家庭刺激、胎龄和社会经济地位独立相关，并且一组相似的变量预测了贝利MDI。
该语言测试可靠，具有可接受的同时效度和预测效度，并且对环境和儿童特征敏感。母亲对语言的报告在大规模项目中可能有用。
