Quality-assessment of disease-specific quality of life questionnaires for rhinitis and rhinosinusitis: a systematic review

The aim of this systematic review was to give a quality-assessed review of the existing disease-specific health related quality of life (QOL) questionnaires concerning rhinitis and rhinosinusitis for adults. The quality is assessed by defining the characteristics of a QOL questionnaire with assessment criteria. The results of the construction, description, feasibility, and the psychometric performance of the instruments are provided. We finally provide a clinician's guide to choose a questionnaire based on the measurement goals, the discriminant validity, responsiveness and the points obtained in the quality assessment. Of the top scoring instruments regarding the overall quality assessment, only four health related QOL questionnaires for rhinitis and rhinosinusitis met our criteria for the discriminant validity and responsiveness
