What this trial studies

This project aims to enhance the understanding of fatigue as a symptom in primary care patients and to develop an accessible treatment targeting fatigue. It involves a randomized controlled trial with 500 participants to evaluate the effectiveness of a novel internet-delivered cognitive behavioral therapy (iFAS) compared to standard care. The primary outcome will measure changes in fatigue severity over a 6-month period, with long-term follow-up extending up to 60 months. The study will also investigate moderators and mechanisms of treatment effects to identify subgroups of fatigued individuals.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-67 with severe, functionally disabling fatigue lasting at least 3 months, who are enrolled in a primary care clinic in Region Stockholm.

Not a fit: Patients with active disease processes or primary psychiatric disorders that require immediate evidence-based treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new, effective treatment for patients suffering from persistent fatigue, improving their quality of life.

How similar studies have performed: Other studies have shown promise in using cognitive behavioral therapy for fatigue, suggesting that this approach could be effective, although this specific application may be novel.
