EEG를 활용한 사람중심 커뮤니케이션 중재 효과성 연구

Abstract

Person-Centered care and communication intervention have been widely utilized in emotional care for people with dementia overseas. However, the use of non-pharmacological interventions, including person-centered care, has been lacking in Korea primarily due to a shortageof scientific evidence proving their efficacy. This study aimed to present Person-Centered communication as a method of intervention andto quantitatively assess its impact on the emotional state and agitation of people with dementia. The subjects of the study, people withmild dementia who commute day care centers, were divided into experimental and control groups for the purpose of comparison. Measurementson brainwaves and observations on changes in emotion and behavior were taken before and after the interventions. Brainwaves were examined by measuring signals from two electrodes of EEG on the prefrontal cortex, and observation were taken with the Observed Emotion RateScale (OERS) and the Agitation Behavior Scale (ABS). As a result of the communication intervention, it was found that emotions such as happiness and attentiveness increased, while anger, anxiety·agitation, and sadness decreased, along with a reduction in agitated behavior. EEG measurements showed a decrease in theta waves which are related to emotions, and significant changes in alpha and beta waves whichare related to attentiveness. This study is meaningful in that it quantitatively confirmed the effectiveness of Person-Centered communicationon the emotions and agitated behavior, as well as EEG changes in people with mild dementia. This study suggests using Person-Centered Care and communication intervention for the emotional support of people with dementia.
