認知症高齢者が作業に従事することの効果—作業開始前，作業実施中，作業終了後の主観的QOLの比較

The activity adaptation effects on a person with senile dementia : The comparison of subjective QOL before, while, and after activities

要旨：認知症高齢者の作業療法の役割として主観的QOL向上が重要と考える．筆者らは介護老人保健施設に入所中の認知症高齢者に様々な作業を試みている．今回，対象者26名に5種類の作業を行い，作業が主観的QOL向上に役立っているか否かを感情を指標とし数量化できる主観的QOL評価を用いて検証した．その結果，全作業，各作業ともに作業中は作業前，作業後より，作業後は作業前より有意に値が高かった．全作業では，作業中と作業後の値に正の相関が認められた．作業中に高まった陽性感情は少なくとも作業後20分程度は保持され，作業中の陽性感情が高いほど，作業後の陽性感情がより高く・長く持続した．

　As a role of occupational therapy for people with senile dementia, the improvement of their subjective QOL is very important. We writers have been trying to care for people with senile dementia under entrance to a geriatric health service facility, with various kinds of activities.

　This time, we investigated the value of these activities for the improvement of senile dementia people's subjective QOL by using the subjective QOL scale which can indicate the subjective QOL with the index of the senile dementia people's emotions. This investigation was based on our research on caring for patients with five different kinds of activities per 26 patients.

　The results in each and all activities showed that the scores of the period while the activities are attended to the patients (hereafter, inside) were intentionally higher than the scores of the period before attending the activities (hereafter, before) and the scores of the period after attending the activities (hereafter, after). The after scores were much higher than the before scores, and the inside scores and the after scores were correlated with each other positively.

　Besides, with regard to the memories of positive affect, the memories of positive affect increased by attending the activities kept maintaining at least 20 minutes. The stronger the inside positive affect was, the stronger and longer the after positive affect was possible to be carried on.
