Translation and cross-cultural adaptation of the pediatric sleep questionnaire (PSQ*) into Brazilian Portuguese

Abstract Introduction Obstructive sleep apnea is a frequent entity in childhood that can lead to important consequences for the health and children's quality of live. Polysomnography is the gold-standard exam to diagnose obstructive sleep apnea, but it is expensive, complex, and poorly affordable in Brazil. The pediatric sleep questionnaire has shown to be a valuable screening test for obstructive sleep apnea. It is a simple questionnaire with good sensitivity and specificity compared to polysomnography in the countries where it has been validated. Objective Translation and cross-cultural adaptation of the pediatric sleep questionnaire (PSQ), into Brazilian Portuguese. Methods The translation of the PSQ into Brazilian Portuguese was carried out in accordance with good practices. The validated and adapted questionnaire was applied to parents/caregivers of 60 children (40 of them with obstructive sleep apnea and 20 controls) aged 2-18 years. Retest was applied to 30 children with obstructive sleep apnea. The following tests were performed: internal consistency, test-retest, validation of questionnaire (the latter by ROC curve). Results Brazilian PSQ has shown high internal consistency by Cronbach's alpha (0.86 for the total test, 0.83 for subscale “snoring”, 0.64 for “sleepiness” and 0.65 for “behavior”). Test-retest presented a correlation of 0.89 for subscale “snoring”, 0.93 for “sleepiness” and 0.86 for “behavior”. Accuracy by ROC curve was 0.99. Nine was considered the optimal value to discriminate patients with obstructive sleep apnea from controls, with a sensitivity of 0.92 and specificity of 1.0. Conclusion The translation and cross-cultural adaptation of the PSQ into Brazilian Portuguese proved to be successful. In places with difficult access to polysomnography, PSQ can be a useful tool in screening and follow-up of children with obstructive sleep apnea.
