3세 아동용 간편어휘력 검사 개발을 위한 기초연구

A Preliminary Study for Development of Screening Version of REVT for the 3 Years of Korean Children

배경 및 목적: 본 연구에서는 언어발달 지체가 될 위험성이 있는 3세 아동들을 선별하는 평가도구를 개발하기 위하여, 기존의 표준화된 어휘 검사도구인 REVT의 문항을 반으로 줄인 간편 어휘선별검사의 신뢰도를 분석하고자 하였다. 방법: 이를 위하여 2011년도에 육아정책연구소에서 실시한 전국의 3세 아동 1,700여명을 대상으로 검사간 상관도와 유의도, 및 백분위 분포도를 분석하였다. 결과: 반분 수용어휘검사 및 반분 표현어휘검사 모두 전체 점수와 매우 높은 상관도를 보였으며, 수용 및 표현어휘 점수 간에는 유의미한 점수차가 나타나지 않았고, 또한 백분위 분포도도 전체 분포도와 유사하게 나타났다. 논의 및 결론: 이러한 결과를 토대로 반분 REVT 검사가 3세 아동의 선별어휘검사로서 활용될 수 있는 방안과 후속연구의 필요성을 논하였다.

Objectives: Many researchers have emphasized the importance of early intervention for the at-risk children in language development. One of the most widely used children's language tests in Korea is the Receptive and Expressive Vocabulary Test (REVT). Since REVT is a comprehensive vocabulary test and covers a wide range of ages, it is often used to test children who have already shown language delays. Thus, the purpose of the present study is to conduct a preliminary study in order to develop a screening version of the REVT for 3-year-old Korean children. Methods: This study analyzed 1,754 data of 3-year-old children collected by the Korean Institute of Child Care and Education (KICCE) in 2011. Full version of REVT was administered and the data were rearranged in three versions: full version of REVT-R (receptive version) or REVT-E (expressive version); odd-half version, which consists of odd number items from REVT-R or REVT-E; and even-half version, which consists of even number items from REVT-R or REVT-E. Results: Results of the study showed that the correlations among the three versions were very high; all three versions showed a slight positively skewed distribution; and there were no significant differences among the versions except between the full version of REVT-R and the odd version of REVT-R. Conclusion: These results indicate that, in overall, odd-half or even-half versions of REVT could be used to assess 3-year-old children's vocabulary abilities. However, further researches should be conducted to test the validity of these short versions of REVT.
