It is a scale based on various physical activities that cause dyspnea. It consists of five items. The patient rates respiratory distress between 0 (no shortness of breath) and 4 (shortness of breath during activities such as being homebound and dressing).

It consists of a 100 mm long horizontal line with the words "none" and "very severe" written on one end. The patient marks the severity of the current respiratory distress on the line using these two degrees as criteria. Scoring is done by measuring the marked area with the help of a tape measure.

Measures the effect of cough on quality of life. It consists of 19 questions. It has psychological, social and physical sub-dimensions. The cut-off value of the scale is not defined; low scores indicate greater effect from cough, i.e. worse quality of life. The total severity score ranges from 3 to 21.

It will be used to evaluate the health-related quality of life of the cases. SGRQ consists of three categories where the symptoms, activities and the effects of the disease on their daily lives are evaluated. The symptoms examined are cough, sputum, wheezing and shortness of breath. Physical functions, housework and hobbies are questioned to determine the activity status. These are activities limited by shortness of breath. The survey consisting of a total of 76 questions is completed in 20 minutes. There is an evaluation scale between zero and 100 points. Zero indicates perfect health status, 100 indicates the worst health status.

Short form-36 is a quality of life scale consisting of 36 items that can be filled by the patient and whose validity and reliability have been shown in studies in patients with musculoskeletal disorders. The Turkish version of SF-36 was used in our study. This scale includes 8 separate health-related headings as physical function (10 items), social function (2 items), physical role limitation (4 items), emotional role limitation (3 items), mental health (5 items), vitality (4 items), pain (2 items), general health (6 items).

Since it evaluates activities of daily living comprehensively and in all dimensions, HAQ was preferred in our study to assess the disability level. It includes 20 questions across 8 domains (dressing, arising, eating, walking, hygiene, reach, grip, and common activities). Each question is scored between 0 and 3 (without any difficulty = 0, with some difficulty = 1, with much difficulty = 2, unable to do = 3). The highest score of each subsection is summed up and divided by 8 to determine the total score between 0 and 3. A high score indicates a low functional level

Disease activity in rheumatoid arthritis will be assessed using the Clinical Disease Activity Index (CDAI). This index is calculated based on four main parameters: the number of painful joints, the number of swollen joints, the visual analog scale of global disease activity as assessed by the patient, and the visual analog scale of global disease activity as assessed by the physician. CDAI scores of 0-2.8 indicate remission, 2.9-10 indicate low disease activity, 11-22 indicate moderate activity, and 22-76 indicate high activity.
