초록
본 연구는 조기선별척도를 통한 학습장애 조기선별의 가능성을 확인하기 위하여 학습장애 위험아동 조기선별척도 개발을 위한 기초 연구를 실시하였다. 이를 위해 학습장애 위험아동 조기선별척도 문항개발과 신뢰도 및 타당도 검증 두 부분으로 나누어 연구를 설계하였다. 연구1에서 문항개발 단계와 내용타당도 검증 단계를 통해 총 62문항을 선정하였다. 연구2에서 본 연구에서 개발된 척도의 1, 2차 검증 단계를 통해 신뢰도 및 타당도를 검증하였다. 1차 검증 단계에서 예비척도 62문항의 문항 적절성을 알아보기 위해, 6~7세 아동 493명을 대상으로 자료를 수집하여 전체-문항 간의 상관을 알아본 결과 모든 문항이 전체와 의미 있는 상관이 나타났다. 예비척도의 구인 타당도 검증을 위해 탐색적 요인분석을 실시한 결과, 5요인 모델의 전체 설명변량이 58.92%로 다소 높게 나타났다. 2차 검증 단계에서 본 척도의 신뢰도를 재검증하기 위해 220명의 7세 아동을 대상으로 자료를 수집하여 5요인의 요인별 문항내적합치도와 재검사 신뢰도를 산출한 결과 높게 나타났다. 이를 통해 학습장애 위험아동 조기선별척도의 신뢰도와 타당도가 1차적으로 검증되었다.
Abstract
The purpose of this study is to develop the Early Screening Scale for Children At-Risk for Learning Disabilities. This study is composed of two parts. First part is to develop of items the Early Screening Scale for Children At-Risk for Learning Disabilities. Second part is to verify validity and reliability of the scale. The results are as following: First, to certificate content validity, items which had been made based on the previous studies and scales were reviewed to 12 experts, and then 62 items were selected. To evaluate construct validity, Confirmatory factor analysis was performed in a sample of 493 kindergarteners (ages 6-7). The Principle Component Analysis fixed 5 factors and the Oblimin Rotation Method were used. In this analysis, the total explanatory variable of 5 factor was 58.92%, which was relatively high. The 5 factors each were named language, behavior, cognition, math, play. This show that the scale is valid. Second, to evaluate internal consistency reliability, a correlation analysis between a total score and each item score was performed. Coefficients were yielded above .40 in all items. Internal consistency of each factor yielded above .80, which were high. Coefficient for test-retest reliability yielded .91, which were very high. This show that the scale is reliable.
