: The reference is from "Psychosomatic Medicine" and it isn't OR to say that it supports the psychosomatic hypothesis, as someone reading it who knows the definition can reasonably come to that conclusion. However, there are numerous articles in newspapers where Drs (medical and PhD) describe it as a psychosomatic phenomenon, as do many sufferers (and many specifically deny it too). I'll look up a few references later. I don't think the claim that some call it psychosomatic is at all controversial. It would be if we said it definately was with no evidence, but this statement is entirely reasonable.
