Abstract

The purpose of this study was to identify the validity, reliability, and discriminative index of the Korean version of Modified Barthel Index (K-MBI). For this, two hundreds twenty-thee stroke patients participated. Activities of daily living were measured through using K-MBI. Factor analysis was performed for identifying the construct validity and internal consistent and discriminative index were calculated. The result of factor analysis was that the 10 items of K-MBI have communality above .50, and was constructed one factor. Explained variance was 72.184%. The order of factor loading value was toileting, personal hygiene, transfer from bed to chair and back, ambulation/wheelchair, dressing, feeding, bowel control, bathing, bladder control, and stair climbing. Cronbach ${\alpha}$ of K-MBI was .994. The range of discriminative index was .783~.909, and was acceptable. One factor of K-MBI was identified through factor analysis, and reliability and discriminative index was also identified. Various psychometric properties of K-MBI should be investigated in further studies for valid assessment of activities of daily living in stroke patients.

이 연구는 뇌졸중 환자를 대상으로 한국판 수정바델지수(Korean Version of Modified Barthel Index: K-MBI)의 타당도, 신뢰도와 문항변별도를 알아보기 위해 실시되었다. 223명의 뇌졸중 환자를 대상으로 K-MBI를 사용하여 일상생활활동을 측정하였다. 타당도를 알아보기 위해 요인분석을 실시하였고, 문항내적 합치도, 문항변별도를 알아보았다. 요인분석 결과, K-MBI의 10개 항목의 공통성은 .50이상으로 나타났으며, 하나의 요인에 적재되는 것으로 나타났다. 설명량은 72.184%이었다. 요인적재량은 용변처리, 개인위생, 의자/침대 이동, 보행/의자차, 옷 입기, 식사하기, 대변조절, 목욕하기, 소변조절, 계단 오르기 순으로 나타났다. K-MBI의 Cronbach ${\alpha}$ 값은 .944로 나타났으며, 각 항목의 문항변별도는 .783~.909로 만족할 만한 수준이었다. 요인분석을 통해 K-MBI의 일상생활활동이라는 하나의 구성요인을 확인하였으며, 신뢰도와 문항변별도를 확인하였다. 뇌졸중 환자의 일상생활활동의 타당한 평가를 위해, 앞으로의 연구에서는 K-MBI의 다양한 심리측정학적 특성을 알아보는 연구가 필요할 것으로 생각된다.
