Objectives:The aim of this study was to examine the reliability and validity of the 18 items of the Dementia ElderlyOdayaka Scale(DEOS)in elderly people with dementia who lived at home.Methods:Ninety-three elderly peoplewith dementia who lived at home and utilized a home-visit nursing service were enrolled.Three evaluators(twonurses and one family caregiver per subject)evaluated each subject twice at an interval of about two weeks.Results:A clinical dementia rating of 2 or 3 was the most common(30％ of enrolled patients).With respect tothe intra-rater and inter-rater reliability,the average difference between the two scores ranged between 0.5 and 0.8 for each item.The intraclass correlation coefficient using the test-retest method was 0.9(P＜0.01),while that ofthe total scores evaluated by the nurses and family members was 0.7-0.8(P＜0.01). The overall Cronbachαcoefficient for the 18-item DEOS was 0.95,while the coefficients for each area ranged from 0.86-0.91.Based on afactor analysis,the 18 items were classified into 3 domains:［Personhood］,［Interactions with surroundings］and［Expression of emotions］.Conclusion:The reliability and validity of the 18 items of the DEOS were verified.
