What this trial studies

This is a longitudinal within-group study of adults with fibromyalgia who complete 10 weeks of internet-delivered exposure-based CBT, with objective pain regulation measured at three time points: about 10 weeks before treatment, within three days before treatment start, and within one week after treatment end. Participants complete weekly electronic questionnaires about pain, fibromyalgia symptoms, and function from baseline to post-treatment, and additional measures of disability, fatigue, avoidance, depression, and anxiety at the three main time points. A licensed psychologist (or supervised trainee) conducts clinical screening and confirms fibromyalgia criteria before inclusion, and participants attend Karolinska Institutet for 3–4 in-person pain tests.

Who should consider this trial

Good fit: Adults (≥18) with a physician-diagnosed fibromyalgia confirmed by the Fibromyalgia Survey Questionnaire, living in Sweden or Finland, with internet access, stable relevant medications, and willingness to attend in-person pain testing and avoid other psychological treatment during the study.

Not a fit: Patients with severe, untreated depressive or anxiety disorders, PTSD, exhaustion syndrome, unstable or unmedicated bipolar disorder, or those unable to attend in-person testing or who live outside Sweden/Finland are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the results could show that online exposure-based CBT produces measurable improvements in pain regulation and symptoms, supporting broader use of this accessible treatment.

How similar studies have performed: Previous randomized studies of internet-delivered exposure-based CBT for fibromyalgia have reported strong effects on core symptoms, so this protocol builds on promising prior results.
