A Tailored Psychological Intervention (MITIG.RA) for Managing Fatigue in Rheumatoid Arthritis

The objective of this study is to examine the efficacy of the Compassion and Mindfulness Intervention for RA (MITIG.RA), a novel intervention combining different components of Cognitive Behavioural Therapy (CBT), compared to treatment-as-usual (TAU) in the management of Rheumatoid Arthritis (RA) associated fatigue. This is a multicentre, two-arm parallel randomized controlled trial. Patients will be screened for eligibility, willingness to participate, and will be assessed and randomized to the experimental (MITIG.RA + TAU) or control condition (TAU) using computer-randomization. MITIG.RA will be delivered by a certified psychologist and comprises eight sessions of 2 hours, followed by two booster sessions. Outcomes will be assessed via validated self-report measures and include levels of fatigue (primary outcome), perceived impact of disease, depressive symptoms, mindfulness, self-compassion, safety, and satisfaction (secondary outcomes). Assessment will take place at baseline, post-intervention, before the first and second booster session (week 12 and 20, respectively), and at 32 and 44 weeks after the interventions\' beginning.
