| Research Abstract |
It has been not elucidated the detailed status of dysphagia among the impaired community-dwelling elderly persons. The purpose of the present study was to develop a new scale, Dysphagia Risk Assessment for the Community-dwelling Elderly (DRACE).
The subjects of the present study were 85 community-dwelling elderly persons with physical or mental impairment. First, 18 symptoms related to dysphagia were evaluated using ordinal scale. The results were analyzed using factor analysis, thus four factors were extracted. Six items were selected from factor 1, three items were selected from factor 2, an item was selected from factor 3, and an item was extracted from factor 4. These 11 items related to dysphagia were determined as evaluation items of DRACE.
Cronbach's alpha of DRACE was 0.84, thus DRACE had enough reliability. Also, DRACE has sufficient construct validity because the score of DRACE was significantly related to two representative clinical assessment of dysphagia such as modified water swallow test and repetitive saliva swallowing test.
Furthermore, dysphagia risk determined from DRACE was significantly related to the concentration of hydrogen sulfide of expired gas, which was a major cause of halitosis. However, frequencies of oral health care were not significantly related to the score of DRACE.
These results suggest that DRACE, which is developed in the present study, will have a sufficient detective power to evaluate the risks of dysphagia in the community-dwelling elderly persons.
