Validity assessment of oral health promotion activities targeting the older population for community care in South Korea: A Delphi study

Abstract

ObjectiveThe purpose of this study was to establish an oral health activity assessment tool for older people and evaluate its validity.BackgroundTo provide reasonable and efficient oral health promotion services with limited medical resources, a tool including categories and items of oral health promotion activities for older people should be prepared.Materials and methodsThe tool initially consisted of 76 items on oral health promotion activities for older people classified into assessment‐performance‐evaluation stages. Topics for each stage included general and oral health, daily health, oral health status, behaviour, and awareness. In addition, two Delphi surveys were conducted on 10 experts who met the selection criteria, and the final items were derived based on the review opinions.ResultsAs a result of the first and second Delphi surveys, the content validity for all items was ≥0.60 and the content validity index was ≥0.80. In the first survey, the degree of convergence in some items was 0‐0.88. After modifying the contents according to expert opinions, the degree of convergence was improved from 0 to 0.50 in the second survey. The degree of agreement ranged from 0.75 to 1.00, indicating that experts agreed. Finally, a total of 65 items were derived.ConclusionA 65‐item tool was derived through two Delphi surveys for the assessment of oral health activities for older people. The use of the tool developed in this study would likely contribute to better prevention of oral diseases and the promotion of oral health among older people.
