Description
Background: This study investigated the effectiveness of a psychoeducational intervention on the quality of life and well-being of patients with myositis, a rare condition that significantly impacts daily life. Methods: All myositis patients in a specific healthcare region were invited to participate. Thirty-four eligible patients were randomly assigned to either an intervention group or a control group. The intervention group received five 100-minute sessions focused on understanding how myositis impacts daily life. Both groups were assessed before and after the intervention using validated tools to measure quality of life, well-being, and self-efficacy in managing the disease. Results: Patients in the intervention group showed improvements in quality of life, well-being, and self-efficacy compared to their pre-intervention scores. These improvements were more pronounced in the intervention group compared to the control group for 70% of the variables studied. Notably, the intervention group experienced a greater reduction in sedentary behavior and an increase in satisfaction with social relationships. Conclusions: This randomized controlled trial, conducted on a representative sample of myositis patients, provides evidence that a psychoeducational intervention can effectively improve healthrelated quality of life, well-being, and self-efficacy in managing myositis.
