Normally I ignore rubbish studies but this one is so bad it deserves a special mention.

Abstracts
Participants were instructed to imagine that either they or a friend were suffering from chronic fatigue syndrome (CFS) and were asked to fabricate a story about how CFS affected their own or their friend's daily functioning. Control participants were not given an imagination exercise but were asked to write about their study choice. After the writing exercise, all participants completed the Symptom Checklist-90 (SCL-90). Participants who had written a story about how CFS symptoms affected daily life (either their own life or that of a friend) had higher scores on the Somatization subscale of the SCL-90 than controls. This finding resembles the misinformation effect documented by memory research,
and suggests that elaborative writing about illness, through its symptom-escalating power, has iatrogenic potential [harm].
The most striking feature of this study is that it doesn't feature any CFS patients, instead using a bunch of psychology undergrads (who may, co-incidentally, have strong views on CFS).
All this shows is that imagining life with CFS affects how healthy people answer a questionnaire taken immediately after that bit of writing - a 'priming' effect that is well-known is pyschology.
There is no comparison group either. They may have had similar findings if they had used MS as the illness instead, but I doubt they would have suggested in that case that the writing was causing 'harm'. The Discussion section speculates:
I haven't read fully, and don't intend to but the full text is available for masochists.
And if writing causes harm, just imagine the effect of talking about symptoms to a consultant for an hour could have. Surely better to have not medical attention at all...
