Development of a health belief scale on oral self-care for older adults:validity and reliability testing
Objective To develop a health belief scale for measuring oral self-care in older adults and to test its reliability and validity.Methods Based on the health belief model,the item pool was formed through literature review and semi-structured interviews,then expert consultation and pilot survey were performed to develop the initial version of the scale.At last,565 community-dwelling ol-der adults were conveniently selected and surveyed to validate the scale.Results The scale included 5 dimensions named as perceived benefits,perceived barriers,perceived severity,perceived susceptibility and perceived self-efficacy,totaling 25 items.Five common factors were identified by exploratory factor analysis,accounting for 71.524％of the total variance.The results of confirmatory factor analysis suggested that the scale had a good model fit(X2/df=2.766,IFI=0.929,CFI=0.928,TLI=0.917,PCFI=0.798,PNFI=0.768,RMESA=0.079).The item-level content validity index(CVI)ranged from 0.833 to 1.000,and the uni-versal agreement scale-level CVI was 0.920.The overall Cronbach's α coefficient was 0.959.Conclusion The health belief scale on oral self-care for older adults has good reliability and validity,which can be used to measure health beliefs on oral self-care in the older population.
