Abstract

|
Objectives: The purpose of this meta-analysis was to investigate the effects of cognitive intervention activities (CIAs) for the elderly with dementia in Korea. We had searched for articles related to cognitive intervention for dementia over the past decade.
Methods: The studies were searched through domestic search engine such as Earticle, KISS, Kyoboscholar, NDSL and RISS. The PEDro scale was used to assess the quality of the studies. The meta-analysis was implemented to analyze statistical values such as the number of samples, mean and standard deviation.
Results: Nine papers were carefully selected for meta-analysis. The PEDro scales of analyzed studies were 4-5 points. The total number of subjects in identified studies was 336. We classified the dependent variables into mental function (MF) and activity and participation (A&P) based on the International Classification of Functioning, Disability and Health to compute effect sizes. The effect size of MF was 0.464 and the effect size of A&P was 0.422, both of which were “medium effect sizes”.
Conclusions: The medium effect sizes for CIAs are clinically acceptable. However, it should be considered that dementia is a degenerative disease. And well designed and high quality research should be implemented continuously.
