Reproducibility of SOHO-5applied to 5-year-oldstudents from public schools in a region from Paraíba sertão area

Aim: This paper aimed to evaluate the reproducibility of the Scale Oral Health Outcomes for Five-Year-Old Children (SOHO-5) applied to public school students in a sertão area in the Paraíba. Methods: The study population consisted of the census of all children in the city with a 5-year-old child (59 students) who underwent a clinical examination based on World Health Organization criteria for dental care (dmft) and application of an oral health-related questionnaire quality of life (SOHO-5). This process was repeated 30 and 60 days after the initial test under the same application conditions for two calibrated examinators. To assess the reproducibility of the SOHO-5 instrument, the concordance correlation coefficient (ρc) was used and a Bland-Altman concordance analysis was performed to assess the variability (limit of concordance) existing between the time points of questionnaire administrations. Results: For the study scenario, there was no agreement between students’ answers regarding their quality of life, as indicated by low values of the concordance coefficient. Furthermore, the 95% confidence intervals of these measures show that these values are not significant because the intervals in the t0 x t2 (-0.11) and t1 x t2 (-0.04) scenarios have “zero”, while the lower bound for the t0 x t1 scenario is 0.29. Conclusions: Therefore, there was no agreement between the standard response of 5-year-old children at three points in time when the questionnaire was administered.
