Abstract
Objective
To develop a scale to determine parents’ attitudes and beliefs regarding fluoride varnish.
Design and methods
This study had a cross‐sectional design and was conducted between 2019 and 2021. A total of 810 parents were included in the study sample. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), discriminant validity, and convergent validity methods were used to estimate the scale validity. For reliability, the Cronbach alpha coefficient, item‐total correlation coefficients, and test–retest method were used.
Results
As a result of psychometric analysis, the scale was found to have a three‐factor structure. The factor loads of the items were between 0.838 and 0.715. The three‐factor construct showed a good fit in confirmatory factor analysis (X2(41): 110.06, p <.001; RMSEA: 0.065; RMSR, 0.02; GFI, 0.95; and NFI, 0.94). Cronbach's α coefficient on the scale was 0.85. The item‐total correlation of the scale was found to be between 0.355 and 0.626. The test–retest intra‐class correlation coefficient of the scale was 0.72.
Conclusions
This study suggests that the developed scale is a reliable tool to evaluate the attitudes and beliefs of parents toward fluoride varnish. It is thought that the scale will make a contribution to public health.
