The diagnostic accuracy of the Arabic version of the Pediatric Sleep Questionnaire for screening for pediatric sleep-related breathing disorders in Saudi children

Abstract

Pediatric Sleep Questionnaire (PSQ) is a valid, reliable tool for screening for sleep-related breathing disorders (SRBDs) translated into several languages since 2000. The diagnostic accuracy of an Arabic version of the PSQ has never been tested. Our aim was to translate the original version of PSQ into Arabic (Arabic-PSQ), validate it as a reliable screening tool, and compare it to the gold standard diagnostic method for SRBDs. This was a prospective longitudinal study of 54 children (2–14 years) who were to undergo polysomnography (PSG). SRBD was assessed by administering the Arabic version of PSQ to the parents of these children. The validity and reliability of the Arabic-PSQ were assessed. Data were analyzed using Stata 16. Correlation between with polysomnographic indices and PSQ scores, as well as measurement of the diagnostic accuracy were determined. Receiver operating characteristic analysis between the mean PSQ scores and binary PSG results was done and the area under curve (AUC) value was calculated. Thirty-four (63%) children were diagnosed with obstructive sleep apnea by PSG (Apnea–Hypopnea Index [AHI] ≥1), 26 of whom were accurately identified with the Arabic-PSQ (76.5%). Arabic-PSQ showed comparable validity and reliability. Using a cutoff of 0.33, the score showed a significant correlation with AHI: Rs: 0.30 (P = 0.029). The sensitivity was 76.5%, the specificity was 50%, the positive predictive was 72.2%, the negative predictive value was 55.6%, the positive likelihood ratio was 1.63, and the negative likelihood ratio was 0.37. The Arabic-PSQ is a valid tool for the screening of Arabic-speaking populations for SRBD. It is valuable for directing the diagnostic approach in a timely and cost-effective manner.
