Summary

This study is creating a Turkish version of a questionnaire that helps find breathing pattern problems in people with COPD. Researchers will test the questionnaire on 90 stable COPD patients to make sure it works well. The goal is to give doctors a better tool to understand and treat breathing difficulties in Turkish-speaking patients.
