Hypothesis
To perform a cross-cultural adaptation of the chronic rhinosinusitis patient-reported outcomes (CRS-PRO) questionnaire, creating a Portuguese version for evaluating patients with CRS.
Conclusion
The Portuguese version of the CRS-PRO questionnaire is a validated and well-accepted tool for assessing CRS symptoms in the Portuguese-speaking population.
Supporting Evidence
- The questionnaire was evaluated in 40 participants who completed it on two separate occasions.
- Twenty participants were patients with CRS, and the other twenty were healthy subjects.
- The ICC values for the CRS with nasal polyps group ranged from 0.65 to 0.89, indicating good to excellent reliability.
- All ICC values were statistically significant at the p < 0.01 level or lower.
- The average time to complete the questionnaire was 1.4 minutes.
Takeaway
Researchers made a new questionnaire in Portuguese to help doctors understand how chronic sinusitis affects patients, and it works well.
Methodology
The CRS-PRO questionnaire was translated using a three-step procedure including forward translation, backward translation, and patient testing.
Potential Biases
Potential biases may arise from the medical professionals' perspectives on the clarity of technical terms.
Limitations
The main limitations include the sample size and focus on participants from a specific geographical region.
Participant Demographics
The average age of participants was 43 years, with 23 men and 20 patients with CRS (60% with polyps).
