Effectiveness Evaluation of a Mobile Application for Rheumatoid Arthritis

It is a scoring system used to determine the disease activity of rheumatoid arthritis. Calculation is made by evaluating the number of tender and swollen joints, erythrocyte sedimentation rate, global assessment of the patient, and VAS measurements using a special type of calculator. Based on the obtained DAS score, DAS 28 ≤ 2.4 is considered remission, 2.4-3.6 indicates low disease activity, 3.6-5.5 indicates moderate disease activity, and ≥ 5.5 is classified as high disease activity.

It will evaluate the quality of life of individuals with rheumatoid arthritis.The obtained result ranges from 0 to 30, with higher scores indicating poorer quality of life.

It consists of 14 items regarding the type of essential fat individuals use in meals, daily olive oil consumption, daily fruit and vegetable portions, daily margarine/butter and red meat consumption, weekly red wine, legumes, fish-seafood, nuts, cakes, and tomato sauce with olive oil consumption. It will be used to evaluate individuals' compliance with the Mediterranean diet. After assigning 1 or 0 points to each item based on the consumption amount, the total score is calculated. A score of ≤ 5 indicates low adherence, 6-9 indicates moderate adherence, and ≥ 10 indicates high adherence.

It provides information about the time individuals spend in light, moderate, and vigorous activities and the time they spend sitting. It will be used to determine the physical activity level of individuals. For each activity level, the MET (Metabolic Equivalent) value is multiplied by the number of days and minutes, resulting in a "MET-min/week" score. The obtained value is classified as physically inactive (MET ≤ 600 energy level), insufficiently active (MET = 600-3000 energy level), and sufficiently active (MET ≥ 3000 energy level).

It is a scale that questions how rheumatological diseases affect the daily lives of individuals.A higher score on the scale indicates functional impairment. The questionnaire assesses the past week and evaluates the patient's difficulty in performing certain activities.

It will be used to determine the fatigue level of individuals with rheumatoid arthritis. It consists of four different subgroups: physical fatigue, fatigue in daily living activities, cognitive fatigue, and emotional fatigue.A higher score on the scale indicates increased fatigue.

It will be used to assess patients' perception of stress.A higher score indicates a greater perception of stress.

This scale was developed to assess the adaptation process of individuals with chronic diseases to their illness. It evaluates factors such as patients' compliance with treatment, adaptation to lifestyle changes, and how they cope with the difficulties brought about by the disease.Higher scores on the overall scale and its subdimensions indicate a higher level of adaptation to the illness.

It will be used to assess the severity of pain experienced by patients. The pain intensity assessment is typically conducted using a 10 cm (100 mm) long horizontal or vertical line, starting with "No Pain" and ending with "Unbearable Pain." The patient marks the appropriate point on the line based on their perceived pain. In this study, the responses provided by patients regarding their pain intensity will be quantified using a 100 mm scale.
