Abstract
In present study, we made the revision of the ODAYAKA (well-being) Scale for dementia elderly peoples (DEOS) using caring facilities. The scale is called "the scale 18-item Version of the DEOS for Dementia (18-items DEOS) " . The purpose of this study is to confirm the reliability and validity of the scale. We targeted 85 dementia elderly peoples over 65-yearsold using caring facilities. The situation of their daily life was evaluated twice by 2 staffs belonging to those facilities through 18-items DEOS. About 40 % of them were CDR 2. With respect to the inter-rater reliability, the average of differences of two scores was between .3 and .6 for each item. The correlation coefficient by the test-retest method was .9 (p < .01). Based on the result of the factor analysis, 18 items were classified into 3 domains: 6 items related to " expression of their own individuality "; 6 items related to "a substantial life" and 6 items related to "interaction with people around them" . By additional statistical analysis (Cronbach alpha coefficient and others) , we verified the reliability and validity for 18-items DEOS for elderly peoples using caring facilities. Then the scale is applicable effectively for those peoples.
