Nothing can illustrate how far DSM
5 has gone off track better than the words spoken in its defense by DSM 5
leadership. Dayle Jones and Suzy Chapman have
assembled (from among many others) the 10 most wrong-headed quotations, and I
have annotated them with my own thoughts.
No!
DSM 5 is most decidedly not "a set of scientific hypotheses"; it is
an official manual that will influence people's lives for better (and sometimes
for worse) in enormously consequential ways. DSM 5 is not a research agenda
"intended to be tested" after its publication; it must hit the ground
safe and scientifically sound. Any DSM 5 proposal for change that lacks strong
evidence should be considered "disproved" right now, without further
ado before publication, not after. Our patients are not guinea pigs for
reckless DSM 5 experimentation.
Again
a resounding no! Allow entrance into DSM 5 only for
changes that have already passed muster. Exclude everything that "has not
been tested as well as we would like." DSM 5 is not a place for the
untried speculations and the pet theories of the assembled experts. Add new
suggestions only if they are well studied and of proven worth and safety.
DSM 5 is introducing a variety of
dimensional measures. Dimensions are more accurate than categories in
describing continuous variables (e.g.,
IQ, height, weight, blood sugar). Providing dimensions could have been a useful
advance if done well. But
the measures suggested by DSM 5 are ad hoc, untested, and so impossibly
time-consuming and unnecessarily complex that they will never be used in
clinical practice. A premature and poorly done dimensional system will have no
result other than to give dimensional diagnosis an undeserved bad name. And it
makes no sense to compare assessing mental disorders to assessing cholesterol
or blood pressure so long as psychiatry has no objective biological tests. Our
diagnoses are now, and will remain for some time, necessarily far less precise
than those in the rest of medicine.
Please spare us a future filled with frequently
convened expert panels; their fickle suggestions will likely do far more harm than good.
Expert panels are largely responsible for the mess DSM 5 is in now. Why so?
Experts live in an ivory tower world and don't appreciate how suggestions that
may work for them can be so badly misused in the real world. We should avoid
making changes arbitrarily and instead wait until scientific discovery makes it
clear that change is necessary. There are no prospects for quick breakthroughs
in psychiatric diagnosis in the near future except for Alzheimer's, where
diagnostic tests may be available in several years.
Not so! The
fear that DSM 5 is conducting a "wholesale imperial medicalization of
normality" originated with me, and I am a great defender of psychiatric
diagnosis and treatment -- but only when it is done well and within its proper
sphere. Most of the widespread criticism of DSM 5 is not directed toward
psychiatric diagnosis in general, but toward the careless way DSM 5 has been
prepared, and toward its disregard for the harmful unintended consequences it
will most certainly cause.
DSM 5 will
dramatically increase prevalence by adding five new, very common
"disorders" that together will mislabel many millions of people now
considered normal. Also, DSM 5 plans to lower thresholds for many of the
existing disorders, turning normal grief into depression and dramatically
increasing rates for attention-deficit disorder and generalized anxiety
disorder. It is simply irresponsible not to be concerned about or measure the
major impact this will have on the over-use of medication, on stigma, and on
the misallocation of scarce resources.
Would that
it were so. DSM 5 literature reviews are remarkably variable in quality; often
one sided, incomplete, and unsystematic; and sometimes giving undue weight to
unpublished papers or papers authored by DSM 5 work-group members. The DSM 5
changes are mostly unsupported by scientific evidence.
DSM 5 is
not-so-subtly warning us that the reliability results from its field trial came
in so low that we should accept a level of diagnostic agreement far below the
universally accepted minimum standards. It wants to include some definitions
whose diagnostic agreements are barely better than chance -- which means they
are useless. The unacceptably low reliability is caused by the remarkably
imprecise DSM 5 writing. This was supposed to be corrected in a second stage of
field testing, but DSM 5 so badly missed its deadlines for the first stage that
Phase 2 had to be stealthily cancelled. Low reliability is unacceptable; DSM 5
should rewrite and retest its poorly performing criteria to ensure that they do
not cause great confusion.
Perhaps this
casual attitude toward time explains why every DSM 5 deadline has been missed
-- some by a whopping 18 months. The poor planning and execution of DSM 5 have
already forced a postponement from its original publication in 2012 to 2013,
and yet another postponement is now necessary if it is to meet even minimal
standards of quality.
This
statement is in response to the request for independent scientific review
contained in a petition endorsed by 47 mental health professional associations.
Because it is internal, secret, and porous, DSM 5's own scientific review
process has no credibility. But contrary to the quote, there is a very clear
and highly desirable alternative. The Cochrane group is expert in conducting
independent, evidence-based scientific reviews to guide medical decision
making. Cochrane should be contracted by APA to review the most contentious
diagnoses. There is no other way DSM 5 can possibly gain the public trust.
* * * * *
This is just a select sample from among any number of equally self-incriminating quotations that consistently hoist DSM 5 on its own petard. The public statements of the DSM 5 leadership consistently reveal just how insulated they are -- far out of touch with the proper purpose of their task and unable to see serious risks that seem perfectly apparent to everyone else. DSM 5 is probably stuck on its disastrous course unless it can finally be restrained by outside forces --some combination of press shaming, public and professional opposition, and/or governmental intervention. Time is running out.
