초록

일상 활동, 삶의 질 등을 고려하여 경도인지장애(MCI)에 대한 조기 개입과 다양한 중재 프로토콜의 필요성이 제기되고 있다. 본 연구는 MCI를 대상으로 한 작업기억 기반 의사소통 중재의 효과를 알아보고, 일반 중재, 의사소통 파트너 동반 중재(CP 중재), 자가 훈련 등 세 중재 방식에 따른 효과의 차이를 반복측정 분산분석으로 검증하였다. 이를 위해 65세 이상의 MCI 노인 총 37명이 참여하였고, 3개 집단(일반 12명, CP 11명, 자가 훈련 14명)으로 분류되어 중재를 적용하였다. 주요 결과는 다음과 같다. 첫째, 작업기억 기반 의사소통 중재는 세 집단의 작업기억, 의사소통(이해, 표현, 화용언어), 주관적 인지-의사소통을 유의하게 향상시켰다. 둘째, 중재 전후의 차이는 CP 중재, 일반 중재, 자가 훈련 순으로 크게 나타났다. 셋째, CP 중재의 효과는 구어 작업기억, 표현, 주관적 인지-의사소통 측면에서 유의하게 높았다. 본 연구를 통해 MCI군에 대한 작업기억 기반 의사소통 중재가 전이 효과를 보이며 적용 방식에 따라 효과성이 상이함을 입증하였다. 본 결과는 MCI 대상의 중재 프로토콜을 고안할 때 효과성을 극대화하고 적용 방식을 다양화하는 증거 기반 자료로 활용할 수 있다.

Abstract

It is necessary to intervene early in mild cognitive impairment (MCI) and apply a variety of protocols in consideration of daily activities and quality of life. The purpose of this study was to analyze the efficacy of working memory-based communication intervention for MCI and its difference by application methods including general intervention, engagement of communication partner (CP), and self-training. The repeated measures ANOVA compared intervention effects across variables. Thirty-seven MCI patients (general 12, CP 11, self-training 14) performed the intervention protocol. The main findings were as follows. Firstly, our intervention protocol improved the performances of working memory, communication (comprehension, expression, pragmatic language), and subjective cognitive- communication. Secondly, pre-post differences in groups were CP intervention, general intervention, and self-training in order. Lastly, the efficacy of CP intervention was noticeable in verbal working memory, expression, and subjective cognitive-communication. This study proves that effects of working memory-based communication intervention for MCI patients are significant, and vary with types of application. Current study also provides the evidence-based information to develop the protocols increasing the efficacy of intervention with various application methods.
