This mindset is unfortunate, and detrimental to patients. There have been a lot of studies on CBT&#x2F;GET, and there isn&#x27;t really any doubt that they are moderately effective. The only issue I have with the treatments is that the theories behind them (deconditioning and abnormal illness beliefs) don&#x27;t really have any evidence. I suspect they work for other reasons. However, that shouldn&#x27;t be a reason to completely reject them.<p>I was speaking to someone recently who recovered from CFS (after being mostly bed-bound) through CBT and lifestyle changes, and she is now completely recovered. In her case there were a lot of recent traumatic experiences which contributed to her illness, so CBT was very helpful in addressing those issues.<p>Some charities, such as Action 4 ME, seem a little more open-minded about CBT.
