A preliminary developmental survey (using DDST) of 1442 Bangkok children who were between the ages of two weeks and six years was conducted between June 1983 and December 1987. The results of this study showed that the 25th percentile for the development of Bangkok children in the areas of personal-social, fine motor adaptive, language and gross motor skills were comparable to the children in original samples in Denver. Although the Bangkok group seems to have passed many test items at earlier ages, the 75th-90th percentile in each test item was generally more delayed in the Bangkok group. The investigative team suggests that further research for the purpose of establishing a norm for the DDST be pursued on the basis of geographical sampling more than socioeconomical sampling that was used in this study.
