ABSTRACT
Caregiver/mother reports have become a valid and reliable assessment method for infants and very young children. The validity and reliability of MCDI(MacArthur Communicative Development Inventories) which consists of parent reports on early lexicon and other communicative/language behaviors have been reported in a number of studies. MCDI was highly correlated with free communicative samples and formal tests. Moreover, MCDI has been adapted to more than 10 languages. The concurrent validity and the test-retest reliability of the Korean adaptation of MCDI(MCDI-K) are examined. Concurrent validity was examined by comparing results from MCDI-K and observed communicative measures. Ninty one-year-old Korean children’s communicative behaviors were compared with their mothers’ reports on MCDI-K. As results, early communicative measures such as the number of different words, the total number of words, the number of different communicative behaviors, and the total number of communicative behaviors were significantly correlated with the number of productive words reported on MCDI-K(r=.576 to r=.790). The test-retest reliability of MCDI-K was also examined. The correlation between the 52 mothers’ first MCDI-K reports and the second reports was .989. These results indicate that the MCDI-K could be used as a valid and reliable instrument to measure young Korean children’s semantic development. MCDI-K, however, needs to be further refined and normed to better diagnose Korean children’s communicative development.
