To develop and validate a questionnaire about fluoride knowledge (FKQ).
Questions to evaluate knowledge about fluoride sources and daily fluoridated water and dentifrices consumption were developed and validated. Sociodemographic data were also collected from the participants, and data were collected for testing their psychometric properties and instrument validation. The model adjustment was tested in 456 dentists, students, and health personnel via confirmatory factor analysis (CFA) with unidimensional categorical indicators. Cronbach's alpha coefficient was used to estimate the instrument's reliability. External validation measurements were represented by questions related to sociodemographic data, fluoride source knowledge and daily practices, and the consumption of fluoride water and dentifrices.
The model showed adequate fit via confirmatory factor analysis (CFA); the fit indices were comparative fit index (CFI) = 0.941, Tucker‒Lewis index (TLI) = 0.927, and root mean square error of approximation (RMSEA) = 0.075, with factorial loadings varying between 0.25 and 0.91. The Cronbach's alpha coefficient for the 13 items was 0.68, demonstrating substantial and adequate reliability in the total instrument.
The FKQ can estimate the knowledge of dentists, dental students, and health personnel about fluoride use.
开发并验证一份关于氟化物知识的问卷（FKQ）。
设计并验证了用于评估氟化物来源知识以及每日氟化水和牙膏使用情况的问题。还收集了参与者的社会人口统计学数据，并收集数据以测试其心理测量特性和工具的有效性。通过具有单维分类指标的验证性因素分析（CFA）在456名牙医、学生和卫生人员中测试模型调整情况。使用Cronbach's α系数来估计该工具的可靠性。外部验证测量由与社会人口统计学数据、氟化物来源知识和日常行为以及氟化水和牙膏使用情况相关的问题表示。
通过验证性因素分析（CFA），模型显示出良好的拟合度；拟合指数为比较拟合指数（CFI）=0.941，塔克-刘易斯指数（TLI）=0.927，近似均方根误差（RMSEA）=0.075，因子载荷在0.25至0.91之间变化。13个条目的Cronbach's α系数为0.68，表明整个工具具有较高且足够的可靠性。
FKQ可以评估牙医、牙科学生和卫生人员关于氟化物使用的知识。
