Abstract

This study examined the effect of cognitive reserve on the cognitive function in adults. In addition, this study investigated the direct and indirect effects of factors, such as subjective memory decline, depression, and quality of life on the cognitive function. The participants consisted of 253 adults who were 40 to 80 years of age. The assessment tools included the cognitive function scale, depression scale, quality of life scale, subjective memory decline, and cognitive reserve scale. The data results were analyzed using SPSS 25.0, and PROCESS macro for SPSS Version 3.3 and bootstrapping were used. The results of multiple mediating of the cognitive reserve and cognitive function in adults did not have a mediating effect in depression and subjective memory decline, and the quality of life showed a complete mediating effect in the relationship between the cognitive reserve and subjective cognitive function. Based on the results of this study, adults must accumulate cognitive reserve continuously through various activities and continuous training so that the cognitive function can lead to a positive direction. Nevertheless, more studies on cognitive reserve and cognitive function in healthy adults are needed.

본 연구는 성인의 인지예비능, 주관적 기억감퇴, 우울 및 삶의 질 등과 같은 요인들이 인지기능에 미치는 직·간접 효과를 규명하고자 하였다. 연구 대상자는 만 40세 이상 80세 미만의 성인 남녀 253명을 대상으로 설문 조사하였고, 본 연구에 사용된 도구는 인지기능 척도, 우울 척도, 삶의 질, 주관적 기억감퇴, 인지예비능 척도를 사용하였다. 데이터 결과는 SPSS 25.0를 이용하여 분석하였고, PROCESS macro for SPSS Version 3.3과 부트스트래핑 방법을 활용하였다. 연구결과, 성인의 인지예비능은 우울과 삶의 질에 영향을 미치는 것으로 나타났으며, 인지예비능과 인지기능의 다중 매개 결과는 우울 및 주관적 기억감퇴에서 매개효과가 나타나지 않았다. 그러나 삶의 질은 성인의 인지예비능과 주관적 인지기능 간의 관계에서 완전매개효과를 나타냈다. 본 연구결과를 토대로 성인들은 다양한 활동과 지속적인 훈련을 통해 인지예비능을 꾸준히 축적하여 인지기능이 긍정적인 방향으로 이어지도록 하는 것이 필요하다. 또한 건강한 성인들을 대상으로 한 인지예비능과 인지기능을 위한 많은 연구들이 실행되기를 제언한다.
