Hypothesis
Can the SNOT-20 questionnaire be effectively adapted and validated for Portuguese-speaking patients with chronic rhinosinusitis?
Conclusion
The SNOT-20 questionnaire was successfully adapted and validated for use in Portuguese, allowing for better assessment of chronic rhinosinusitis in Portuguese-speaking populations.
Supporting Evidence
- The internal consistency of the SNOT-20p was high with a Cronbach's alpha of 0.91.
- Test-retest reliability showed a high correlation (r = 0.994).
- The questionnaire demonstrated significant discrimination between patients with and without chronic rhinosinusitis.
Takeaway
Researchers made a questionnaire to help people with sinus problems express how they feel, and they made sure it works well in Portuguese.
Methodology
The study involved translating the SNOT-20 questionnaire into Portuguese and validating it through a series of tests for reliability and sensitivity.
Limitations
The study was conducted in a single center, which may limit the generalizability of the findings.
Participant Demographics
Median age of participants was 42.5 years, with 63% being men.
