Validation of a Spanish version of the Sleep‐Related Breathing Disorder scale of the Pediatric Sleep Questionnaire in children living in a high‐altitude city

Abstract

Objectives We aimed to validate a Spanish version of the Sleep‐Related Breathing Disorder scale of the Pediatric Sleep Questionnaire (SRBD‐PSQ) in children living in a high‐altitude Colombian city. Methods In a prospective cohort validation study, patients aged between 2 and 17 years who attended the Ear, Nose, and Throat pediatric department of our institution for symptoms related to sleep‐related breathing disorders had a baseline visit at enrollment, a second visit the day scheduled for the surgical intervention, and a follow‐up visit at least 3 months after the surgical intervention. In these three visits, we gathered the necessary data for assessing the criterion validity, construct validity, test–retest reliability, internal consistency, and sensitivity to change of the Spanish version of the SRBD‐PSQ. Results In total, 121 patients were included in the analyses. The exploratory factor analysis (generalized least squares method, varimax rotation) yielded a four‐factor structure, explaining 65.93% of the cumulative variance. The intraclass correlation coefficient (ICC) of the measurements was 0.887 (95% CI: 0.809–0.934), and the Lin concordance correlation coefficient was 0.882 (95% CI, 0.821–0.943). SRBD‐PSQ scores at baseline were significantly higher than those obtained after adenotonsillectomy surgery (median [IQR] 11.0 [9.0– 14.0] vs. 4.00 [1.50–7.0]; p < 0.0001). Cronbach's α was 0.7055 for the questionnaire as a whole. Conclusions The Spanish version of the SRBD‐PSQ has acceptable construct validity, excellent test–retest reliability and sensitivity to change, and adequate internal consistency‐reliability when used in pediatric patients living at high altitude with symptoms related to sleep‐related breathing disorders.

Questionnaires for snoring children: Altitude matters

“…On the other hand, Villalobos-Aguirre et al, 1 found a very high proportion of patients with severe OSAH; this phenomenon may be related to the use of sea level scoring rules instead of high altitude parameters; further, it could also explain why no significant differences were found in the questionnaire values among the three categories of OSAH severity.…”

“…To the Editor, I am writing in relation to the publication featured in the May 2021 edition of PEDIATRIC PULMOLOGY entitled "Validation of a Spanish version of the Sleep-Related Breathing Disorder scale of the Pediatric Sleep Questionnaire in children living in a high-altitude city" by Villalobos-Aguirre, et al 1 In this research, conducted at 2650 m of altitude, American Academy of Sleep Medicine scoring criteria for obstructive sleep apnea/hypopnea (OSAH) were used. This, I believe, is an error because it is known that sleep physiology changes at high altitude.…”
