Fibromyalgia Syndrome (FMS) is a complex chronic pain disorder characterized by widespread pain associated with numerous symptoms. It is more common in women over 50 years of age with low educational and socioeconomic status living in rural areas. Pain Science Education (PSE) is one of the most widely used treatments for chronic pain management. This treatment consists of an educational intervention aimed at reconceptualizing and modifying erroneous cognitions regarding pain in these patients. The objective of this study is to evaluate the effectiveness of PSE in patients with FMS living in rural areas. They will be randomly assigned to one of two treatment groups. The intervention group will receive two adapted in-person sessions (90 minutes per session/week) by a therapist experienced in teaching PSE. The control group will begin the conventional treatment they received before participating in the study. After the end of the study, patients in the control group will be given their intervention group records. The variables measured will include the impact of FMS on daily life, pain sensitivity, central sensitization, pain catastrophizing, fear of movement, anxiety and depression, self-efficacy, and assessment of knowledge and beliefs about PSE. Assessments will be conducted before the intervention, after the second PSE session, and three months later by the same researcher.
