ABSTRACT
The purpose of this research was to supplement the preceding study and to examine the feasibility of standardizing the Bayley Scales of Infant Development (BSID) for Korean infants. The subjects of this research were 93 healthy infants at 1-12 months of age living in Seoul. Seventy were the sam a infants as the subjects of the preceding research. Statistical analysis of the results was done by Item analysis and scalogram analysis using Green`s method. The scalability of the BSID for Korean infants was .78 on the mental scale and .8l on the motor scale. Item order by counting positive responses was slightly different from the original BSID item order. On the feasibility of standardization of the BSID in Korea, the results showed that: 1) The BSID is scalable for Korean infant development, and 2) The BSID needs correction in item rank order.
