Cognitive behaviour therapy for chronic fatigue syndrome: a multicentre randomised controlled trial

Area of Science:

• Medical research
• Psychological interventions
• Chronic illness management

Background:

• Chronic Fatigue Syndrome (CFS) presents treatment challenges, with questions about the generalizability of Cognitive Behaviour Therapy (CBT) outside specialized centers.
• A randomized trial was conducted to compare CBT with guided support groups and the natural disease progression.

Purpose of the Study:

• To evaluate the efficacy of Cognitive Behaviour Therapy (CBT) for Chronic Fatigue Syndrome (CFS) in a multi-center setting.
• To compare CBT's effectiveness against guided support groups and the natural course of CFS.

Main Methods:

• A randomized trial involving 278 eligible patients diagnosed with CFS across three centers.
• Patients were assigned to CBT (13 therapists), support groups, or a control (natural course).
• Multidimensional assessments of fatigue severity and functional impairment were conducted at baseline, 8, and 14 months, with intention-to-treat analysis.

Main Results:

• Cognitive Behaviour Therapy (CBT) demonstrated significantly greater effectiveness in reducing fatigue severity and functional impairment compared to both support groups and the natural course at 14 months.
• Support groups did not show a significant advantage over the natural course for CFS patients.
• Within the CBT group, clinically significant improvements were observed in fatigue severity (35%), functional status (49%), and self-rated improvement (50%).

Conclusions:

• Cognitive Behaviour Therapy (CBT) proved more effective than guided support groups and the natural course in a multi-center trial involving multiple therapists.
• The study indicated a lower proportion of patients achieving clinically significant improvement with CBT compared to trials featuring a small number of highly specialized therapists.
