Biopsychosocial approaches are recommended in rheumatic diseases. Because the nature of these diseases is based on the person's ability to cope with their chronic disease. Moreover, rheumatic diseases, which are included in chronic diseases; It creates a comprehensive picture with loss of function, fatigue, insomnia, sexual reluctance, negative mood, social isolation and persistent pain accompanying them. This picture requires comprehensive treatments to include the symptoms. For this reason, biopsychosocial models are drawing attention day by day and it is underlined that a holistic approach to rheumatic patients is necessary. For all these negative conditions, exercise offers treatment as an important parameter. However, it seems that no named, exercise-based biopsychosocial models recommended for rheumatic diseases have been encountered. Studies show that cognitive behavioral therapies play a role when it is necessary to approach this patient group holistically. Patients diagnosed with rheumatism, who have applied to Hacettepe University Faculty of Health Sciences Physiotherapy and Rehabilitation Department since 2004, were included in group training where they could do clinical pilates exercises. Dance therapy-authentic movement was added to the exercise program in order to break the physiological connection of the vicious circle between the awareness gained in 2009 and the pain and anxiety. In 2010, the relationship between anxiety and pain led to the addition of knowledge management in sexuality this time. It was published in the form of a rheumatism book in 2014. In 2015, BETY received trademark registration. In this process, the patients learned to manage their inflammatory pain during the day by applying the pain management strategy individually. The exercise program, which was applied for one hour 3 days a week, was created by applying scales for the diagnosis of diseases during the evaluation phase.However, the patients stated that the relevant scales did not show the change in themselves, and that they experienced different changes. During this period, patients were asked to form sentences expressing the characteristics of change. The sentences formed were simplified by removing the same ones. These sentences were tested on rheumatic patients who did not participate in the BETY group. The item pool was formed by making additions related to activities of daily living. The draft was sent to rheumatologists and their opinions were taken. The opinions of the rheumatologists were shared with the patients, and the final version of the items was given in 2017. This scale was started to be applied to individuals with rheumatism who participated in the BETY program. It was also used for evaluation purposes for patients who did not participate in the exercise group but were given a home program after only the first interview. In this process, which formed the basis for the development of a scale, a qualitative study was needed that investigated the recovery characteristics of the patients and the reasons for their persistence in exercise. This qualitative study aims to reveal in detail the change created by an exercise-based biopsychosocial model in patients with rheumatism. Putting all these mentioned processes in writing and presenting them to the literature will be the efficiency of this study.
