Long-term outcome of cognitive behavior therapy versus relaxation therapy for chronic fatigue syndrome: a 5-year follow-up study.
Deale, A, Husain, K, Chalder, T et al.·The American journal of psychiatry·2001
Researchers compared two types of therapy for ME/CFS: cognitive behavior therapy (CBT, which focuses on changing thought patterns and gradually increasing activity) and relaxation therapy. After 5 years, 68% of people who received CBT reported feeling much or very much improved, compared to 36% who received relaxation therapy. However, neither therapy fully eliminated fatigue symptoms, and some patients found it hard to keep improving after their regular treatment ended.
