주관적 인지장애를 호소하는 지역사회 노인에 대한 다요인 인지능력 향상프로그램(‘씽씽두뇌 발전소’)의 효과성 검증을 위한 비교 연구

Objectives: This study explored the effects of nonpharmacological multifactorial memory improvement program (‘Ssing-Ssing Doonoi baljeonso (SSD)’) developed by the National Center of Mental Health in 2015 in community-dwelling elderly complaining of subjective memory impairment (SMI). Methods: A randomized, controlled, 8-weeks trial of SSD with double-blind assessments at baseline and end-point of treatment. A total of 117 elderlies with SMI were recruited from 10 community-based welfare centers in Seoul, Korea. Participants were randomly assigned to two groups: SSD and art therapy group. 8 sessions of treatment were administrated to the groups. Results: SSD significantly improved immediate recall, delayed recall of word memory test, all items of the logical memory test, and immediate recall, delayed recall, and recognition of the visuospatial function test (all p<0.05). Korean short version of Geriatric Depression Scale(S-GDS-K) was also significantly improved, and Memory Efficacy Questionnaire(MEQ), Prospective-Retrospective Memory Questionnaire(PRMQ), and Korean Dementia Screening Questionnaire(K-DSQ) were all significantly improved. In particular, compared to the art therapy group, the K-DSQ showed better results(time * group, F(1, 114)=6.585, p=0.012, η2=0.055), and S-GDS-K was a tendency to improve in SSD group (time * group, F(1, 114)=3.596, p=0.060, η2=0.031). Conclusion: Our multifactorial memory training program significantly enhanced memory, visuospatial function, mood and subjective memory efficacy. Compared with art therapy, SSD had more advantages in memory function of daily life and showed a tendency to improve depression. It is likely to be applied as a nonpharmacological treatment for the prevention of cognitive decline in the elderly with SMI/MCI.
