초록

목적: 본 연구의 목적은 수행기반 인지기능 평가를 위한 예비연구로써 노인의 인지기능 저하 선별하기위해 사용되는 수행기반 인지기능 평가도구를 분석하여 평가 문항을 구성하고 정상 노인을 대상으로검사를 시행하여 타당도를 검증하는 것이다. 연구방법: 수행기반 인지기능 평가항목을 선정한 후, 만 65세 이상 정상 노인 9명을 대상으로 평가를시행하였다. 평가도구의 신뢰도를 검증하기 위해 수집된 자료를 대상으로 내적 일관성을 분석하였으며, 공인 타당도를 검증하기 위해 기존 수행기반 인지기능 평가와 MMSE-K와의 상관관계를 분석하였다. 결과: Performance-Based Cognitive Function Test(PCFT)의 내적일치도 Cronbach’s α 계수는 운동과제.871 인지과제 .959 높은 신뢰도를 나타냈다. 공인타당도는 운동-인지 이중과제 평가를 이용하여 PCFT의항목별 상관관계는 .755~.964으로 산출되었으며 통계적으로 유의하였다(p<.05). 또한 인지평가도구인MMSE와의 상관관계는 .849~.943(p<0.01)로 나타나 높은 타당도를 보였다. 결론: 본 연구를 통해 수행기반 인지기능 평가의 신뢰도 및 타당도를 검증하였다. 추후 연구에서는 최종적으로 수정 보완된 인지기능저하 노인을 선별을 위한 수행기반 인지기능 평가도구를 대상으로 기타 신뢰도및 타당도를 검증하여야 할 것으로 사료된다.

Abstract

Objective: The purpose of this study is to conduct a preliminary research for the development of a Performance-Based Cognitive Function Test (PCFT) to screen the elderly for cognitive function impairment, and examine the reliability and validity of the test. Methods: A draft version of the Performance-Based Cognitive Function Test (PCFT) was developed and utilized in nine healthy elderly individuals. In order to verify its reliability, we analyzed the internal consistency of the PCFT. In order to verify the concurrent validity of the PCFT, this study analyzed the correlation between motor-cognitive dual task assessments and the Korean version of the Mini-Mental State Examination (MMSE-K). Results: The internal consistency of the PCFT for motor and cognitive tasks was 0.871 and 0.959 (Cronbach’s α), respectively. Concurrent validity of the PCFT, which was performed through motor-cognitive dual task assessments, ranged from 0.755 to 0.964 (Spearman’s rho statistic, p < 0.05). In addition, correlation between the cognitive assessment tool and the MMSE-K ranged from 0.849 to 0.943 (p < 0.01). Conclusion: This study verified, and established the reliability and validity of the PCFT. Further studies are required to examine other psychometric properties in a modified PCFT, for screening cognitive function impairments in the elderly.
