Introduction The aim of this study was to analyse the psychometric performance (reliability and validity) of the TAPQOL questionnaire in measuring the global quality of life in children with central airway obstruction (CAO), which encompasses pathologies with a low prevalence that have a common anatomical or functional affectation. Method The study population consisted of 109 patients with CAO attended in a national reference airway unitafter signing informed consent. The TAPQOL questionnaire was used to measure the global quality of life and its psychometric characteristics were analysed. The reliability was determined using Cronbach's α statistic and the validity was determined by means of a principal component analysis. Results The mean age was 4.8 years and there was no predominant sex. The most frequent diagnosis was laryngomalacia (24.5%), followed bysubglotticstenosis (20.2%). The lowest score in the TAPQOL questionnaire was obtained for the scales of anxiety (66.2 ± 23.7), respiratory (67.9 ± 29.6), and conduct 68.2 ± 21.4). The Cronbach's α was above 0.7 in the majority of the scales and the validity study by principal component analysis with a total variance of 76.7% fits the original 12‐component model. Conclusions TAPQOL is a valid tool to measure the health‐related quality of life in patients with CAO. Measuring it in these patients indicates which fields are most affected, highlighting therapeutic needs that have not been resolved but which can be approached in normal clinical practice.
