There have been a number of studies on Cognitive Behavioral Therapy (CBT) and Graded Exercise Therapy (GET) for ME/CFS based on a treatment model where the disease is perpetuated by cognitive processes. Although the studies are flawed and the model lacks scientific support, the treatments are described as evidence based. The studies are non-blinded and rely on subjective outcomes. There are no objective measures of adherence. The diagnostic criteria vary, and the participating patients often have one or several psychiatric diagnoses apart from suffering from chronic fatigue. The underlying model has no theoretical foundation and is at odds with physiological findings. Surveys suggest that the efficacy of CBT is no better than placebo and that GET is harmful. Therefore, cognitive behavioral therapy and graded exercise therapy for ME/CFS are not evidence based.
