Also, there are differences between cephalometric results and clinical evaluation. This study pretends to validate experts' clinical diagnosis test (ECDT) as gold standard for severe VFE, with the purpose of validating further against it the cephalometric measures results. Methods A consensus (Delphi method) was done to dete rmine if ECDT could be used as gold standard for evident VFE (n=12 experts). A scale of 9 items was initially built from literature. Validity: A convenience sample was used (n=24), which were tested by 3 experts twice. Principal factor analysis was made. Internal consistency was evaluated with Cronbach's alpha coefficient. Inter-observer and intra-observer agreement was measured using Kendall concordance coefficient. ECDT's medians were compared between groups with VFE, using Kruskal Wallis test.Results Eleven of the twelve experts agreed that clinical diagnosis can be used as a gold standard for VFE. After Principal factor analysis a 6 items' scale was made. Internal consistency was high (Cronbach's alpha= 0.8051). ECDT's medians were different in groups with different qualitative appreciation of VFE by experts, in first (p<0.0001) and second evaluation (p<0.0001). A significant interobserver agreement was found (Kendall taub, p<0,01), and a significant intra-observer agreement too (Kendall tau-b, p<0.0005). Conclusions Experts' clinical diagnosis test (ECDT) could be used as gold standard for VFE. Later on, Cephalometric measures should be evaluated using the experts' clinical diagnosis as gold standard. 2007 artículo científico 0124-0064 https://www.redalyc.org/articulo.oa?id=42219062008 en http://www.redalyc.org/revista.oa?id=422 Revista de Salud Pública application/pdf Universidad Nacional de Colombia Revista de Salud Pública (Colombia) Num.3 Vol.9 |
