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.
