ABSTRACT

The purpose of the present study was to investigate the validity of parental report on their children s expressive language. T wenty nine normal children and mother s of them participated in the study. Each mother was asked to mark expressive vocabulary of her child on the MCDI- K checklist and to give an swer s to the questions of SELSI. T hen , spontaneous language sampling analysis and the Picture Vocabulary T est were administered to asses s the children s expressive language ability . The result s were analyzed with Pear son s simple product -moment correlation coefficient s. The major findings from this study were: (1) Correlation coefficient s between the parental report scores and Picture Vocabulary T est scores were relatively high (p < . 01); (2) correlation coefficient s between the parental report scores and MLUm, TNW, NDW values were relatively high (p < . 01); (3) correlation coefficient s between the parental report scores and T T R values were not significant ; (4) difference of correlation coefficient s between boy s and girls was not significant ; (5) difference of MCDI-K correlation coefficient s between mother s who has brought up their children more than 4 day s in a week and mother s who has not was not significant ; (6) difference of SELSI correlation coefficient s between mother s who has brought up their children more than 4 day s in a week and mother s who has not was significant . These result s indicates that parental report is valid to as sess the infants language ability.
