아동의 표현어휘 지연 예측 요인 연구: 3세 말늦은 아동과 정상 언어발달 아동의 가정환경의 질 차이를 중심으로

Abstract

The purpose of this study is to examine the influence of home environment quality on children’s expressive vocabulary development by comparing the home environments of 3-year-old late talkers and typically developing children. The study used the data of 1,723 3-year-old children from the Korean Children’s Panel Study 4th wave data (2011) of the Korea Institute of Child Care and Education (KICCE). Frequency analysis, t-test, and logistic regression were performed to analyze the data. The Early Childhood HOME(ECHOME) was used to measure the quality of home environment and a new variable ‘overall home environment’ was created to represent the average of the six sub-domains of home environment quality. T-test results indicated significant differences in the overall home environment quality and every sub-domain between 3-year-old late talking children and typically developing children. Logistic regression analysis revealed that the overall home environment quality at the age of 3 was a significant predictor distinguishing the two groups. When all six sub-domains were included as an independent variable, learning materials and diversity demonstrated significant influences. This study emphasizes the significance of home environment quality as a predictor of expressive vocabulary delay and identifies specific sub-domains that influence children's language development.
