Simon Wessely refers to the hostile attitude of Chronic Fatigue
Syndrome (CFS) patients to the involvement of some psychiatrists in the
field of CFS (1). One interpretation is that this is due to some sort of
prejudice. I would like to suggest that alternative explanations are
possible.
Rehabilitative strategies such as Graded Exercise Therapy (GET) and a
form of Cognitive Behavioural Therapy (CBT) based on encouraging CFS
patients to do more activity, have long been championed by him and some of
his colleagues as safe and effective evidence-based treatments for the
condition.
However, high rates of adverse reactions to exercise programmes have
been reported (2), information that rarely if ever is imparted by many
psychiatrists when these treatments are being recommended.
The efficacy of rehabilitative therapies for CFS may not as large as
people are led to believe: a meta-analysis of CBT for CFS (which included
GET programmes) estimated the Cohen's d effect size to be 0.48 (3), less
than the 0.50 threshold generally set for a treatment to be seen to have a
moderate effect.
CFS is increasingly being recognised as heterogeneous condition (4).
However, many psychiatrists give the impression that rehabilitative
strategies for CFS will be safe and effective for all, rather than for sub
-groups.
Patients often prefer management strategies based around the pacing
of activities. A US trial of non-pharmacological interventions found that
a programme based around the pacing of activities produced better results
than the CBT and exercise programmes (5). Yet, for some reason, many from
the psychiatric profession will not recommend pacing to CFS patients.
I posit that, looking at the issues in this way, one can see that it
is not necessarily an inherent prejudice that causes some patients to
question psychiatry's involvement in the field.
Incidentally, one of the reasons that patients objected last year to
the CFS conference Prof. Wessely refers to is that, on the six-person
organising committee, the four members with a special interest in CFS all
happened to be psychiatrists!
