Abstract:
Objective:Based on the characteristics of grassroots disease prevention and control centers, medical institutions, and personnel involved in the prevention and control of drinking water-borne endemic fluorosis in China, the aim of this study is to develop a competency evaluation tool for grassroots personnel involved in the prevention and treatment of the disease.Methods:Through literature review and expert consultation, a competency evaluation tool was designed and developed. The tool was distributed nationwide via the Wenjuanxing platform. Valid data were collected and analyzed for item discrimination, validity, and reliability to assess its measurement effectiveness.Results:A total of 150 valid questionnaires were collected, covering 13 provinces across China (67 males, 83 females). The evaluation tool demonstrated significant differences in scores between high and low groups for all items ( P < 0.001). The correlation coefficients between each item and its corresponding factor ranged from 0.77 to 0.87, with factor loadings ranged from 0.68 to 0.97. In the validity analysis, root mean square error of approximation ( RMSEA) was 0.07, and standardized root mean square residual ( SRMR) was 0.03. The goodness-of-fit indices were as follows: goodness-of-fit index (GFI) = 0.94, normed fit index (NFI) = 0.96, incremental fit index (IFI) = 0.95, tucker-lewis index(TLI) = 0.96, and comparative fit index (CFI) = 0.96. In the reliability analysis, the overall Cronbach's α coefficient was 0.91, and the split-half coefficient was 0.88. Conclusions:The competency evaluation tool for grassroots personnel in the prevention and treatment of drinking water-borne endemic fluorosis exhibits high item discrimination, as well as good overall reliability and validity. It can be used to evaluate the competency of prevention and treatment personnel and to study influencing factors.
