About this study
In our study, we aimed to evaluate the validity and reliability of the Turkish version of theAssessment of Burden of COPD (ABC) Scale.
Read the detailed description
Chronic obstructive pulmonary disease (COPD) is a common pulmonary disease characterized by airway limitation, irreversible, preventable, and treatable (1,2). COPD is a major health problem that affects the entire world and is expected to be the fourth, the seventh, cause of death in 2030 (3). The concept of "holistic assessment of disease burden" is widely used to support the personalized care management of COPD patients. Disease burden; physical, psychological, emotional and / or social burden felt by the patient. When the questionnaires in the literature evaluating the quality of life / health status in COPD patients were examined, it was seen that none of these questionnaires included all aspects of COPD burden definition (4). Clinical COPD Questionnaire (CCQ) is a 10-question questionnaire that assesses COPD burden in most aspects and situations. Assessment of Burden of COPD (ABC) Scale was developed to evaluate the burden of disease in COPD patients by adapting this questionnaire. The ABC scale was formed by combining three items (a short tool for early identification of distress) and a substance that measures fatigue with the questions of the CCQ scale. As a result, a scale of 14 items with 5 fields was formed.

What is being measured
The primary outcome is the main question the study is designed to answer.
Assessment of Burden of COPD (ABC) Scale
The ABC scale is a 14-item newly developed COPD burden assessment questionnaire that the person responds to on their own. The scale includes questions that are objective determinants of COPD disease burden integrated with the health status of the patient. There is a total score and 5 subtitle scores; symptoms (4 items), functional status (4 items), mental condition (2 items), emotional condition (3 items) and fatigue (1 item). Scoring is done between 0 and 6 (0 = no disease burden, 6 = high disease burden).
Measured: 3 Minutes
