Abstract
AIMS: To develop and validate the Knowledge Questionnaire in Pediatric Asthma, in the brazilian Portuguese language.METHODS: The questionnaire was developed based on recognized international instruments. Experts have examined the instrument, along with parents of children with asthma. The tests of construct validity and contents, Cronbach’s alpha, intraclass correlation coefficient, Pearson Correlation, analysis of Kappa and ROC curve.RESULTS: Participated in this study 132 parents of children with asthma, and 117 (88.6%) female, average age of 35.9 ± 9.1 years, 78 (59.1%) with full high school, 73 (59.8%) in the economy class C. The final version of the instrument possessing 20 questions, with cut-off of ≥ 14 points. The total scores obtained “A” concept validity tests/construct and value of 0.69 on Cronbach’s alpha. In the evaluation of correlation intraclass coefficient the questionnaire has within the acceptable levels (ICC = 0.69; 95% CI = 0.61 ~ 0.77; p < 0.001). The sensitivity and specificity have lodged area of 0.93 (95% CI: 0.84 ~ 1.0; p = 0.002) and values of 80% and 97.1%, respectively. After applying the final version of the questionnaire of knowledge in Pediatric Asthma, only 5 (3.8%) the parents showed satisfactory levels of knowledge in asthma.CONCLUSION: The Knowledge questionnaire in Pediatric Asthma has proven to be reliable, clear and with suitable levels of reproducibility and internal consistency. Your application is easy and covers the cultural aspects, as well as Brazilian great accuracy in measuring the level of knowledge about asthma.

No contexto da Teoria de Resposta ao Item é comumente utilizado a estimação ou calibração dos itens aonde avalia-se, para cada item, qual o valor de theta exigido para a obtenção de 50%, fornecendo maior precisão aos escores dos testes
Summary
Desenvolvimento e Validação do Questionário de Conhecimento em Asma Pediátrica (Q-CAP) para população brasileira. OBJETIVO: Desenvolver e validar o Questionário de Conhecimento em Asma Pediátrica (Q-CAP), na língua portuguesa brasileira. Especialistas analisaram o instrumento, juntamente com pais de crianças com asma. Foram realizados os testes de validade de construto e conteúdo, alfa de Cronbach, coeficiente de correlação intraclasse, correlação de Pearson, análise de Kappa e curva ROC. A versão final do instrumento possuí 20 questões, com ponto de corte de ≥14 pontos. Os escores totais obtiveram conceito “A” nos testes de validade/constructo e valor de 0,69 no alfa de Cronbach. Na avaliação da correlação do coeficiente intraclasse o questionário possui níveis dentro dos aceitáveis (ICC=0,69; IC95%=0,61~0,77; p
