In 2002, the Belgian government started with the development of CFS "Reference Centers", which implement a "psychosocial" model.
The medical practices of these CFS Centers are defined by the Superior Health Council, e.g. treatment should be based upon Cognitive Behavioral Therapy (CBT) and Graded Exercise Therapy (GET); and biological assessments and treatments of ME/CFS should not be employed.
Recently, the Belgian government has evaluated the outcome of the treatments at the CFS Centers. They concluded that a "rehabilitation therapy" with CBT/GET yielded no significant efficacy in the treatment of ME/CFS
