The Spanish version of the PSQ could be a suitable tool both for screening patients who require medical tests and for epidemiological research. Our objective was to evaluate its reproducibility in the clinical setting.Material and methods: 62 patients in pediatric age were gathered consecutively, 53% were male with a mean age of 5.15 years old (± 3.05) to whom a conventional polysomnography (PSG) was performed because of a probable diagnosis of SAHS. The 24 items of the PSQ (validated Spanish version for sleep- related breathing disorders) were completed at the Pediatric Outpatient Clinic and the night before the sleep study performed at the Respiratory Care Sleep Unit, both data were compared to let show discrepancies between PSQ scores.Results: The mean PSQ score at the Pediatric Outpatients Clinic was 9,42 (± 4,77) and the previous score prior the PSG at the Sleep Unit was 8,7±4,99, with a correlation between both of 0,66 (p <0,0001). The statistical concordance between the two determinations of PSQ was moderate considering the cut line when 33% of the items were positive (kappa index 0.4, p= 0.003).Conclusion: The PSQ score is highly variable when administered sequentially to a clinical pediatric population being evaluated for a potential sleep-related breathing disorder.
