I think that this is too strong. It's probably fair to say that psychological interventions seem to be no more effective than placebo, and don't seem to lead to statistically significant improvements of more objective measures of outcome, and that lots of patients report problems with them. I don't really follow the different CFS and ME criteria debates much though. I didn't see anyone saying that you don't have PEM, or the other stuff. I could have missed it though, as there were some long responses here.
