A Novel Approach to Treating CFS and Co-morbid Health Anxiety: A Case Study.
Daniels, Jo, Loades, Maria E · Clinical psychology & psychotherapy · 2017 · DOI
Quick Summary
This study looked at treating ME/CFS in one patient who also had anxiety about their health. Instead of using standard treatments alone, doctors used a customized approach combining techniques for both the physical fatigue and the worry about health. After 8 sessions, the patient's symptoms improved significantly and stayed better a year later, suggesting this combined approach might help others with ME/CFS.
Why It Matters
Most current ME/CFS treatments produce only modest improvements, and health anxiety often co-occurs but remains untreated. This study suggests that addressing both physical symptoms and health-related anxiety together—rather than separately—may be more effective and efficient, potentially offering a faster treatment course than standard approaches.
Observed Findings
- One patient with CFS and comorbid health anxiety achieved non-case status for both conditions after 8 treatment sessions.
- Clinically significant and reliable reductions were observed across all physical and psychological symptom measures.
- Treatment gains were maintained at 12-month follow-up.
- The individualized, collaborative approach was acceptable to the patient.
Inferred Conclusions
- An adapted cognitive-behavioural model addressing the mutually maintaining relationship between CFS and health anxiety may yield positive outcomes.
- Treating anxiety specifically alongside CFS symptoms may improve overall treatment efficacy and reduce treatment duration compared to standard first-line interventions.
- Individualized formulation-driven treatment may be superior to generic treatment protocols for complex CFS cases.
Remaining Questions
- Does this treatment approach work for other ME/CFS patients, or was this patient's response unique?
- What specific features of the individualized intervention were most therapeutic—the anxiety focus, physical symptom management, or collaborative formulation?
- Can these results be replicated in a randomized controlled trial with a larger sample?
What This Study Does Not Prove
This single-case study cannot establish whether this treatment works for most ME/CFS patients or prove that health anxiety causes CFS symptoms. The dramatic improvement in one patient does not mean all patients will respond similarly, and without a control group, we cannot rule out placebo effects or natural recovery. Correlation between anxiety reduction and symptom improvement does not prove causation.

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 →
