The socio-demographic characteristics of the patients and their relatives will be obtained by asking to them by mutual interview method.
A disease-specific test, the COPD Assessment Test (CAT), will be used to assess patients' own health, and the St George Respiratory Questionnaire (SGRQ) will be used to assess patients' quality of life.
Comorbidities reported by the patient and their relatives will be filled in the Charlson Comorbidity Index. The dyspnea that patients encounter in their daily lives will be questioned with the Modified Medical Research Council (mMRC) Dyspnea Scale.
The "Individual Knowledge Statements of Patients and Resident Proxies" will be used for the individual information of the patient and their relatives about the disease and general health.
There is no control group in the study. SGRQ, CAT and numerical rating scale will be used for the validity of the Turkish version of Individual Knowledge Statements of Patients and Resident Proxies. For the test-retest, the evaluation will be done again after 15 days.
