Abstract

The purpose of this study was to verify the validity and reliability of the computerized general neurocognitive test using intuitive evaluation techniques to reflect the needs of the elderly and to validate neurocognitive function appropriately. The subjects were 100 elderly people who were over 60 healthy people. To evaluate the comprehensive neurocognitive function of the elderly, Computerized Neuro-cognitive Function Test (CNT, cybermedic. Co., Korea) developed by CyberMedic was used. The test consist of attention test, memory test and the problem solving ability test. As a result of correlation analysis of CNT test items, it was possible to confirm the characteristics of measuring single domain of attention and memory test. The problem-solving ability test also showed a high level of significant correlation, although the purpose of measurement was different, but a comprehensive cognitive function test for problem solving was possible. In the reliability analysis, the half reliability and internal consistency of test - retest were significantly higher. As a result of the above study, we conclude that the comprehensive neurocognitive test items constituted in this study have achieved reproducibility and effectiveness.

본 연구에서는 고령자의 신경인지 기능의 정량적이고 객관적인 평가를 위해 개발된 직관적 평가 기술이 접목된 전산화 종합 신경인지 검사 방법에 대한 타당도와 신뢰도를 검증하고자 한다. 피험자는 신체 건강한 60대 이상 고령자를 100명을 대상으로 실험을 진행하였다. 고령자의 종합적인 신경인지기능을 평가하기 위하여 (주)싸이버메딕에서 개발한 전산화 종합 인지기능검사(Computerized Neuro-cognitive Function Test: 이하 CNT, cybermedic. Co., Korea)를 사용하였다. 검사는 주의력 검사, 기억력 검사와 문제 해결력 검사로 구성하였다. CNT의 검사항목별 상관분석 결과, 주의력 검사와 기억력 검사에서 주의력이라는 단일영역을 측정하는 특성을 확인할 수 있었다. 문제해결력 검사에서도 측정 목적은 다르지만 문제해결을 위한 포괄적인 인지기능검사가 가능하고 높은 수준의 유의한 상관관계를 확인 할 수 있었다. 신뢰도 분석에서 검사-재검사에 대한 반분신뢰도 및 내적 일치도는 유의하게 높은 수준을 보였다. 위 연구 결과, 본 연구에서 구성한 종합 신경인지 검사 항목이 재연성과 유효성을 확보하였다고 판단된다.
