The purpose of this study was to investigate the response characteristics of the Korean LDS of toddlers suffering from language developmental delay. The participants comprised 135 toddlers who were 18 to 35 months old. They were assessed at a child psychiatry clinic and rehabilitation centers in Seoul. The K-BSID-II and the Korean LDS were used as the measuring tools. The results were as follows: First, the Vocabulary scores and Mental scales of the 18 to 23 month old subjects showed a significantly positive correlation. The Vocabulary scores, Phrase length scores and Mental scales of the 24 to 35 months old subjects showed significantly positive correlations. Second, the Vocabulary scores revealed no differences between toddlers with or without language delay who were in the 18 to 23 months old group. The Vocabulary scores and Phrase length scores of -the 24 to 35 months group suffering from language delay was significantly lower than the normal language development group. In addition, the effect size of- Vocabulary scores was moderate compared to low Phrase length scores. This study verified the validity of the Korean LDS as a very useful tool for assessing language development delay in toddlers.
