The purpose of this pragmatic, investigator-initiated, multicentre randomised controlled trial is to study the effectiveness and feasibility of a mobile app-based self-management intervention for patients with rheumatoid arthritis (RA), aiming to improve self-efficacy for the management of RA-related symptoms. The intervention consists of education, lifestyle advice and remote monitoring elements and is based on principles of goal setting, self-efficacy theory and behavioural economics, embedded within a platform supported by motivational features and gamification. The primary endpoint is defined as achieving at least a minimal clinically important difference in arthritis-related self-efficacy (the ASES-score) at the follow-up visit in favour of the intervention group when compared to the control group. Moreover, although qualitative studies have highlighted concerns among both patients and healthcare professionals that mobile apps might induce illness behaviour by increasing patients' awareness of their symptoms, this has rarely been studied in detail. Consequently, data regarding the effects of remote monitoring on symptom hypervigilance remain limited and conflicting. Therefore, this trial additionally aims to assess (as a key secondary objective) if a mobile app-based intervention is associated with changes in pain catastrophising, as a conceptualisation of hypervigilance to symptoms.
