This set of questions allows to discriminate children at high risk of obstructive sleep apnea (OSA) and to screen which patients need promptly objective diagnostic tests and treatment. Objective: To validate the Pediatric Obstructive Sleep Apnea Screening Tool to be used in Brazil, in a Portuguese language version. Methods: The Brazilian version of the questionnaire was developed as following: a) translation; b) back-translation; c) conclusion of final version and d) pretesting. The questionnaire was applied previously to the polysomnography in 3 to 9 years old children included in the study from October 2015 until October 2016. Validity and reliability were the psychometric proprieties evaluated. The comparison between polysomnography results and the questionnaire`s cumulative score allowed the accuracy evaluation. Results: Sixty patients were included in the final sample. Accordingly to the polysomnography, 29 (48%) patients had normal apnea and hipopnea index and 31 (51,7%) presented abnormal results. The minimum O2 saturation level was significantly lower among children with OSA (p=0,021). Satisfactory concordance was observed between the apnea and hipopnea index and the questionnaire score. The Brand Altman bias plot was 0,1 for the difference between two measures, with 5,34 (IC95% 4,14 to 6,55) of upper limit agreement and -5,19 (IC95% -6,39 to -3,98) of the agreement lower limit. The questionnaire?s internal consistency calculated by Cronbach's alpha was 0,848 (IC95% 0,780-0,901). Conclusion: The Pediatric obstructive sleep apnea screening tool was translated and validated to an adequate Brazilian-Portuguese version. The questionnaire presented satisfactory results of reliability and concordance in relation to the apnea and hipopnea index. / Introdu??o: O Pediatric obstructive sleep apnea screening tool ? um question?rio com 6 itens de avalia??o de dist?rbios respirat?rios do sono em crian?as de 3 a 9 anos de idade. ? um instrumento de f?cil aplica??o que consegue discriminar as crian?as com maior risco para s?ndrome da apneia obstrutiva do sono (SAOS) e, consequentemente, que necessitam com maior brevidade de exames objetivos para o diagn?stico e do in?cio do tratamento. Objetivo: Validar o question?rio Pediatric obstructive sleep apnea screening tool para o seu uso no Brasil, em uma vers?o em portugu?s. Materiais e m?todos: A vers?o brasileira do question?rio foi desenvolvida a partir das seguintes etapas: a) tradu??o; b) retro-tradu??o; c) conclus?o da vers?o final e d) pr?-teste. A vers?o brasileira do question?rio foi aplicada previamente ao in?cio da polissonografia em pacientes de 3 a 9 anos que foram inclu?dos no estudo no per?odo de outubro de 2015 a outubro de 2016. As propriedades psicom?tricas avaliadas foram validade e confiabilidade. A acur?cia foi avaliada pela compara??o entre os resultados da polissonografia com o escore cumulativo do question?rio. Resultados: A amostra final do estudo foi composta por sessenta pacientes. Vinte e nove (48%) pacientes apresentaram ?ndices de apneia e hipopneia normais e 31 (51,7%) apresentaram resultados alterados conforme os resultados da polissonografia. A satura??o m?nima de O2 (p=0,021) foi significativamente menor entre os pacientes com s?ndrome de apneia obstrutiva do sono. O ?ndice de apneia e hipopneia apresentou concord?ncia satisfat?ria com os resultados do question?rio. Foi identificado um vi?s m?dio de 0,1 para a diferen?a entre as medidas, com um limite superior de 5,34 (IC95% 4,14 a 6,55) e um limite inferior de -5,19 (IC95% -6,39 a -3,98). A consist?ncia interna do question?rio avaliada pelo ? de Cronbach foi de 0,848 (IC95% 0,780-0,901). Conclus?o: O question?rio Pediatric obstructive sleep apnea screening tool foi traduzido e validado adequadamente para a vers?o em portugu?s brasileiro. O question?rio apresentou boa confiabilidade e concord?ncia com o ?ndice de apneia e hipopneia.
