라쉬 모형 적용을 통한 양육태도 검사 양호도 분석

The Analysis of The Child-rearing Attitude Test Appropriateness by Rasch Rating Scale Modeling

이 연구는 장애아동 어머니의 양육태도 검사 연구에서 사용되고 있는 어머니 행동 연구도구(Maternal Behavior Research Instrument: MBRI) 4개 하위 영역에 라쉬 모형을 적용하여 문항 난이도와 적합도 및 평정 척도의 적절성, 분리신뢰도를 평가하는데 그 목적이 있었다. 이를 위해 뇌성마비 아동 어머니 109명을 대상으로 MBRI를 이용하여 양육태도를 알아본 자료에 대해 문항반응이론에 기초한 라쉬 분석을 실시하였다. 문항의 적합도 분석 결과, 거부적과 자율적 태도 영역에서 부적합한 문항이 있는 것으로 나타났으며, 개인 속성 점수와 난이도 비교 결과 문항개발이 필요한 것으로 나타났다. 평정 척도의 적절성을 알아본 결과 척도 변환이 필요한 것으로 나타났으며, 분리신뢰도를 통해 신뢰도와 타당도를 알아본 결과 신뢰도와 타당도가 낮은 것으로 나타났다. 이 연구는 양육태도 검사의 4개 하위 영역에 대해 라쉬 모형을 적용하여 문항을 분석함으로써, 양육태도 검사 문항의 문제점을 알아보았다는데 그 의의가 있다.

The purpose of this study was to analysis of item appropriateness, the level of item difficulty, the appropriateness of rating scale, and separation reliability through applying Rasch model to 4 categories of Maternal Behavior Research Instrument (MBRI) which used for the test of child-rearing attitude of the mother of children with disabilities. For this, the data of 109 mothers of children with cerebral palsy resulted by MBRI was used for analysis of Rasch based on the item response theory. The results were follows: First, the item appropriateness analysis showed that misfit items were in the categories of denial and autonomous attitude. Second, the level of item difficulty of MBRI needed to develop items. Third, 5-point rating scale was not appropriate for MBRI. Fourth, the analysis of reliability and validity by separation reliability suggested that MBRI had low reliability and validity. This is suggested that the items of MBRI may be modified to improve usefulness of the test of child-rearing attitude in mother of children with cerebral palsy.
