French translation and validation of the Sinus and Nasal Quality of Life Survey (SN-5) in children

Résumé

PurposeChronic rhinosinusitis (CRS) is a frequent, quality-of-life (QOL) impairing disease in pediatrics. The SN-5 is a reliable, sensitive and reproductible QOL questionnaire, validated in English for evaluation of CRS disease-specific QOL in children. This study aims to adapt and validate the French version of this test.MethodsThe SN-5 score was adapted into French language through a forward-backwards translation process, and validated through a monocentric prospective controlled study. Inclusion criteria were 2–12 years of age, CRS symptoms for at least 12 weeks, or absence of sino-nasal symptom for controls. Reproducibility was assessed through Spearman's correlation between initial answers and a re-test conducted 15 days later. Internal consistency was measured through Cronbach's alpha, construct validity through Spearman's correlation between items, discriminative ability through Mann-Whitney tests.Results40 patients and 37 controls filled the score between November 2019 and March 2020. Retest was returned by 35 patients and 35 controls. Mean cases age was 8.5 ± 2.6 years old. 26 patients had primary CRS, 10 had cystic fibrosis, 4 had ciliary dyskinesia. All had diffuse disease. Mean SN-5 overall score was 3.63/7 ± 6.4 for CRS patients and 1.89/7 ± 0.9 for controls (p < 0.001). Test-retest coefficient was 0.84 (0.70–0.92; p < 0.001), Cronbach's alpha was 0.83 for CRS patient. Item per item construct validity was good to excellent.ConclusionsThe French version of the SN-5 showed good statistical properties, with good test-retest reliability, internal consistency, structural validity and discriminative ability between CRS and control patients.
