This study tested whether two common treatments for ME/CFS—cognitive behavioral therapy (CBT) and graded exercise therapy (GET)—work equally well in real-world clinical settings. Researchers found that both treatments reduced fatigue, anxiety, and depression, and improved physical functioning similarly. They also discovered that changes in how patients think about their symptoms (measured by a questionnaire) were linked to improvements in fatigue, regardless of which treatment they received.
Understanding whether CBT and GET perform similarly in clinical practice versus controlled trials is crucial for patients and clinicians making treatment decisions. This study provides real-world evidence about treatment effectiveness and identifies metacognition as a potential mechanism of change, which could inform how treatments are refined and delivered.
This observational study cannot establish causation—the association between metacognitive changes and fatigue improvement does not prove that changing thinking patterns causes fatigue reduction. The study also does not explain why real-world outcomes were poorer than trial results, nor does it determine which treatment is objectively superior for specific patient subgroups. It does not address whether GET might cause harm in some patients, a concern raised by some ME/CFS advocates.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
