Rehabilitative efficacy of cognitive behavioral therapy-based intervention for chronic fatigue syndrome: A systematic review and meta-analysis.

In 30 seconds

This systematic review and meta-analysis assessed cognitive behavioral therapy (CBT) for fatigue, physical functioning, and psychological health in people with chronic fatigue syndrome. It included 15 randomized controlled trials involving 2270 participants. After treatment, CBT was associated with reduced fatigue on the Chalder Fatigue Questionnaire (standardized mean difference [SMD] = -0.44, 95% confidence interval [CI]: -0.57--0.32) and improved physical functioning (SMD = 0.32, 95% CI: 0.23-0.41). Follow-up analyses also found benefits, while adverse event rates did not differ significantly. The authors conclude CBT may be effective, with further research warranted.

Key findings

• Posttreatment fatigue decreased on the Chalder Fatigue Questionnaire (SMD = -0.44, 95% CI: -0.57--0.32).
• Physical functioning improved after treatment (SMD = 0.32, 95% CI: 0.23-0.41).
• At 6-24 months, fatigue relief (SMD = -0.35, 95% CI: -0.50--0.19) and functional gains (SMD = 0.21, 95% CI: 0.06-0.37) were maintained.
• Adverse event rates did not differ significantly between groups (odds ratio = 0.61, 95% CI: 0.36-1.01, P = .060).

Why it matters

The pooled trial evidence suggests CBT may improve fatigue and physical functioning in chronic fatigue syndrome, with benefits also observed at follow-up. Psychological outcomes improved as well. These findings help characterize potential benefits and safety, while the review’s conclusion that further research is needed underscores that the results should be interpreted as evidence of possible benefit rather than definitive proof.

What to keep in mind

The review reports inconsistent prior findings and divergent long-term outcomes; heterogeneity was assessed using subgroup and sensitivity analyses. The authors state that further research is warranted.
