Abstract

Abstract: PURPOSE: Constructing a measurement tool of oral health literacy, and testing its reliability and validity, so as to provide a scientific basis for evaluation of oral health literacy of Chinese residents. METHODS: Convenient sampling was used to select the permanent population of a community in Xiaodian District, Taiyuan City, Shanxi Province from March to April 2020. The first draft of the oral health literacy scale was formed through literature review, expert consultation and cognitive interviews. General demographic characteristics, Spearman rank correlation, item analysis, exploratory factor analysis, confirmatory factor analysis and Cronbach's α coefficient were analyzed to evaluate and verify the scale using SPSS 22.0 and AMOS 22.0 software package. RESULTS: A total of 1 000 questionnaires were issued in this study, and 858 effective questionnaires were retrieved. Through project analysis and exploratory factor analysis, a total of 90 items were formed including 5 dimensions containing basic skills, information-related capabilities, oral health maintenance capabilities, personal characteristics, and social support. The score of each item was related to the score of the dimension (r=0.250~0.744, P<0.001). Confirmatory factor analysis showed that the overall fit index of the model was acceptable, where χ²/df=2.785, RMSEA=0.057(95% CI: 0.052~0.0762), IFI=0.931, TLI=0.856, CFI=0.895, the Cronbach's α coefficient of the total scale was 0.899, and the Cronbach's α coefficient of each dimension was between 0.709 and 0.920. CONCLUSIONS: The oral health literacy measurement tool constructed in this study has good reliability and validity, which can be used by dental practitioner in the prevention, treatment, and health education of oral diseases.
