Abstract

The purpose of this study was to evaluate the effects of a computerized cognitive training(CCT) on cognitive, depression, life satisfaction and activity of daily living in older adults with mild dementia. The participants were 32 older adults diagnosed with mild dementia who reside in nursing hospital and were randomly divided into an 16 for an experimental group and 16 for a control group. A CCT was performed for a day/week for 8 weeks in an experimental group. The CoTras-G was used for CCT. The MMSE-K, SGDS-K, ELS and BI were administered to the experimental group and the control group in the same way in order to examine the effects of CCT. The difference of the effects between before and after a CCT conduction were identified by paired t-test. Moreover, the Mann-Whitney U-test was conducted to identify differences in variances between groups. Only participants in the experimental group reported significant improvements in cognitive function, depression, life satisfaction and activity of daily living when compared to those in the control group after CCT. There was a significant difference in cognitive function, depression, life satisfaction and activity of daily living between the experimental group and the control group after CCT. These findings suggest that the CCT can be used as effective cognitive training program to improve cognitive function, depression, life satisfaction and activity of daily living in older adults with mild dementia.

본 연구는 경도치매노인을 대상으로 컴퓨터 인지훈련 프로그램이 인지기능, 우울, 생활만족도와 일상생활활동에 미치는 효과를 알아보기 위해 시행되었다. 연구대상자는 요양병원에 거주하는 경도치매노인 32명으로, 무작위 대조군 전후설계를 사용하여 실험군과 대조군으로 16명씩 무작위 할당하고 실험군에는 8주 동안 주 1회, 총 8회 컴퓨터 인지훈련프로그램을 적용하였다. 컴퓨터 인지훈련 프로그램은 CoTras-G를 사용하였으며, 컴퓨터 인지훈련 프로그램의 효과를 알아보기 위해 실험군과 대조군에 사전, 사후 동일하게 MMSE-K, SGDS-K, ELS, BI를 실시하였다. 컴퓨터 인지훈련 프로그램이 미치는 효과에 대한 전 후간 차이 검증은 paired t-test, 중재 후 실험군과 대조군간의 변화량 차이 검증은 Mann-Whitney U 검정을 실시하였다. 그 결과 실험군이 대조군에 비해 중재 후 인지기능(t=-4.39, p=0.001), 우울(t=4.11, p=0.001), 생활만족도(t=-8.53, p=0.000)와 일상생활활동(t=-3.10, p=0.007)에서 유의미한 향상을 보였으며, 실험군과 대조군의 사후 비교결과 인지기능(U=54.00, p=0.005), 우울(U=76.50, p=0.045), 생활만족도(U=56.00, p=0.007)와 일상생활활동(U=59.50, p=0.008)에서 유의미한 차이를 보였다. 따라서 본 연구는 컴퓨터 인지훈련 프로그램이 경도 치매노인의 인지기능, 우울, 생활만족도와 일상생활활동을 향상시키기 위해 활용 가능한 효과적인 프로그램임을 제시한다.
