Deale and her coworkers conducted a trial with 53 patients with chronic fatigue syndrome to determine whether CBT could help such patients over the long term. Twenty-eight of the subjects received 13 sessions of relaxation therapy, and the remaining 25 got 13 sessions of CBT. Relaxation therapy consisted of engaging in progressive muscle relaxation and rapid relaxation techniques. CBT consisted of planned activity and rest, a sleep routine, graded increases in activity, and a cognitive restructuring of counterproductive beliefs. For instance, subjects worked on thinking of symptoms as “hurting, not harming”—for example, not to equate muscle pain with muscle damage. They worked on eliminating counterproductive thoughts such as “If I can’t do something as well as I used to, it’s not worth doing,” “I have to do as much as I can whenever I’ve got the energy,” and “I’ll never get better.”
