Cross-cultural adaptation (phases and steps leading to adapted and validated QoL tool)_
Cross-cultural adaptation of the original NOSE questionnaire in five steps, according to emerging guidelines ( Two experts in rhinology blinded one to another translated the original NOSE questionnaire. A third expert reviewed both translations and created a new version. A fourth expert reviewed it, blinded to both initial versions. The latest version was sent to a translator with no medical background to form and backtranslate. A board of experts (3 rhinologists, 1 audiologist, 3 general ENT consultants, 1 family medicine practitioner, 1 ENT specialist in training, 1 non-medical translation consultant) reviewed results and synthesized the final version of NOSE-si. It was proofread, and the final report was created. | |
| The pilot phase consisted of submitting NOSE-si to a limited number (n=33) of patients in the study group and control group. | |
| Both the study and control group were enrolled. Retesting was scheduled 7-14 days after the initial testing for the study group and controls (90 patients). Patients had to fill out the same questionnaire and send it back to the researchers. | |
