Summary |
Objectives |
In chronic rhinosinusitis (CRS), SinoNasal Outcome Test-16 (SNOT-16) is a specific quality of life (QoL) questionnaire, validated in English and existing in a French translation. The present study assessed the psychometric characteristics of the French translation in nasal polyposis (NP).
Methods |
The QoL of 40 NP patients was assessed before and after endoscopic ethmoidectomy, with the generic Study Short Form 36 (SF-36) and the specific SNOT-16 questionnaires.
Results |
SF-36 scores were improved 1 year postoperatively. The SNOT-16 Cronbach ⍺ coefficient was 0.81. In the preoperative course, SNOT-16 scores correlated with the mental composite score ([MCS]: P=0.034; rho=−0.36) and the role-physical ([RP]: P=0.02; rho=−0.39), vitality ([VT]: P=0.008; rho=−0.44) and role-emotional ([RE]: P=0.035; rho=−0.36) dimensions of the SF-36. SNOT-16 scores were poorer in women (P=0.03) and in case of aspirin intolerance (P=0.044). SNOT-16 scores were significantly lower 1 year after surgery (P=0.0017).
Conclusion |
The SNOT-16 seemed, in the present series, to be a reliable, valid and sensitive questionnaire. Validation on a larger series could enable its use in the French NP population to assess the precise effectiveness of therapeutic strategies.
