Turkish Version of the Individual Knowledge Statement Questionnaire of Chronic Obstructive Pulmonary Disease (COPD)

Investigation of the Psychometric Properties of the Turkish Version of the Individual Knowledge Statement Questionnaire of Chronic Obstructive Pulmonary Disease (COPD) Patient and Resident Proxies

The Individual Knowledge Statement Questionnaire of Chronic Obstructive Pulmonary Disease (COPD) Patient and Resident Proxies questionnaire, which can be used in patients with Chronic Obstructive Pulmonary Disease (COPD) and their relatives, will be adapted into Turkish and its psychometric properties will be examined, and the knowledge level of patients and their relatives about the disease and general health will be investigated.

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.
