Introduction: The Pediatric obstructive sleep apnea screening tool is a short hierarchical 6-item questionnaire developed to evaluate sleep disordered breathing in 3 to 9 years old children. 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.
