About this trial
Dysfunctional breathing is a common and clinically relevant problem in patients with chronic obstructive pulmonary disease (COPD), contributing to increased dyspnea perception, reduced exercise tolerance, and impaired quality of life. The Nijmegen Questionnaire (NQ) is a widely used symptom-based instrument for screening dysfunctional breathing; however, a validated Turkish version for patients with COPD is currently unavailable.
This observational methodological study aims to translate, culturally adapt, and evaluate the validity and reliability of the Turkish version of the Nijmegen Questionnaire (NQ-TR) in individuals with stable COPD.
