Erm... why should there be further research to explain this? The explanation is clear -- the therapy isn't appropriate. It doesn't work. Do we need further research to explain why standing out in the rain singing Reggae songs doesn't work to reduce fatigue in postpolio syndrome? Or why eating clams on Thursdays doesn't reduce fatigue in postpolio syndrome?
I find it incredibly irritating that the assumption is that this therapy
should work and it is therefore necessary to do more research to explain why it doesn't. No, the freaking therapy doesn't work. You just proved it. Move on. Find a new field of research. Retire. Whatever. Let it go already.
They need further research to explain why therapists continue to push a therapy shown to
harm patients.
Time for us to be the researchers and the psychoquacks to be the subjects. I'm sure there's plenty of good potential topics:
Ambiguity Catastrophizing in Psychotherapists Treating Unexplained Illness
Persistence of False Treatment Efficacy Beliefs in Psychotherapists Treating Unexplained Illness
Treatment Obsessions in Psychotherapists Treating Unexplained Illness
Any other ideas?
