This is a presentation I'd done during my Psychiatry residency. I evaluated the Preamble of the DSM5, evaluating how and why the new manual was conceived, the process of creation and review and the rationale behind these changes.
I also evaluated the reasons why DSM5 has come in for such attack, and did a critique of the very obvious shortcomings in the execution and implementation of the stated aims.
2. Overview
• The Felt Need for DSM5
• Revision Process
– Work groups
– Proposals for Revisions
– Field Trials
– Reviews
• Cultural Issues
• The Multiaxial System
• Definition of a Mental
Disorder
• Organisational Structure
– Dimensional Diagnosis
– Developmental / Lifespan
Approach
3. Definition – Preamble
• “an introductory statement; especially the
introductory part of a constitution or statute that
usually states the reasons for and intent of the law”
Merriam-Webster
• “an introduction to a document, speech, or report
explaining its purpose”
• Macmillan English Dictionary for Advanced Learners
4. The Felt Need for DSM5
• “…past science was not mature enough to yield fully
validated diagnoses – i.e. to provide consistent, strong
and objective scientific validators of indl DSM
disorders”
• “Speculative results do not belong in an official
nosology, but DSM must evolve in the context of other
clinical research initiatives”
• “The boundaries between many disorder ‘categories’
are more fluid over the life course than DSM-IV
recognized”
• “Many symptoms assigned to a single disorder may
occur, at varying levels of severity, in many other
disorders”
5. The Revision Process
•American Psychiatric
Association
•WHO Division of Mental
Health
•World Psychiatric
Association
•National Institute of Mental
Health
•“Stimulate research that would enrich the empirical database
before the start of the DSM-V revision process”
•“Devise a research and analytic agenda that would facilitate the
integration of findings from research and experience in animal
studies, genetics, neuroscience, epidemiology, clinical research, and
crosscultural clinical services”
6. “It can be concluded that the field of psychiatry
has thus far failed to identify a single
neurobiological phenotypic marker or gene that
is useful in making a diagnosis of a major
psychiatric disorder or for predicting response
to psychopharmacologic treatment”
“Such an accomplishment would help move the
specialty into the mainstream of modern
medicine, where etiology and pathophysiology
have replaced descriptive symptomatology as
the fundamental basis for making diagnostic
distinctions”

11. Working Groups
1. Revisions must be feasible for routine clinical practice
2. Recommendations for revision should be guided by
research evidence
3. When possible, continuity should be maintained with
previous DSM editions
4. No a priori constraints should be placed on the degree of
change from DSM-IV to DSM5
• Change Diagnostic Criteria
• Add new disorders, subtypes & specifiers
• Delete Existing Disorders
12. Field Trials
1. Medical/Academic
Settings
Large sample sizes required to test
diagnostic hypotheses on
•reliability
•clinical utility
2. Routine Clinical
Practice (RCPs)
Tested how proposed revisions
performed in everyday clinical
settings when used by a range of
clinicians
(General + speciality psychiatrists,
Psychologists, Counselors, Therapists,
Nurses)

17. Dimensional Approach to Diagnosis
• Previous DSMs considered each diagnosis separate
from health and other diagnoses
– Failed to capture widespread sharing of symptoms and
risk factors across many disorders
– Focused on excluding false positive results
• Diagnostic spectra study group examined if
scientific validators could inform possible new
groupings of related disorders
– Within existing categorical framework
– Used to suggest grouping of disorders, e.g. internalising
v/s externalising
18. Dimensional Approach to Diagnosis
• Shared Neural
substrates
• Family traits
• Genetic Risk Factors
• Specific Environmental
Risk Factors
• Biomarkers
• Temperamental
antecedents
• Abnormalities of
emotional or cognitive
processing
• Symptom Similarity
• Course of Illness
• High co-morbidity
• Shared treatment
response
19. Developmental/Lifespan Considerations
• DSM5 organisation
– Begins with diagnoses thought to reflect developmental
processes manifesting early in life
• Neurodevelopmental, Schizophrenia Spectrum
– Followed by diagnoses manifesting in adolescence / young
adulthood
• BPAD, Depressive & Anxiety Disorders
– Ends with diagnoses relevant to adulthood & later life
• Neurocognitive
• Grouping of disorders after Neurodevelopmental into
– Internalising
– Externalising
– Neurocognitive
– Other Disorders
20. Developmental/Lifespan Considerations
• Encourage study of underlying pathophysiological
processes giving rise to diagnostic comorbidity &
symptom heterogeneity
• Facilitate identification of potential diagnoses by
non-mental health professionals
• Guide clinicians to explain to patients why over a
lifespan they recd
– multiple diagnoses
– additional / altered diagnoses
21. Cultural Issues
• Judgment of given behaviour being abnormal and requiring
clinical attention depends on cultural norms
• Awareness of culture may correct mistaken interpretations
of psychopathology
• Culture may contribute to vulnerability and suffering
• Culture may provide coping strategies to enhance resilience
& suggest help seeking /health care options of various
types
– Alternative & complementary health systems
• Influence acceptance or rejection of diagnosis and
adherence to treatment
• Affect conduct of clinical encounter
– Accuracy & acceptance of diagnosis, treatment decisions
22. Cultural Issues
• Culture Bound Syndrome replaced by
1. Cultural Syndrome
2. Cultural Idiom of Distress
3. Cultural explanation or perceived cause
23. The Multiaxial System
• DSM5 moved to a non-axial documentation of diagnosis
– Separate notations for important psychosocial & contextual
factors (earlier Axis IV) and disability (earlier Axis V)
• Consistent with DSM-IV stance that the multiaxial system DOES
NOT imply that
– There are fundamental differences in the conceptualisation of
Axix I, II or III disorders
– That mental disorders are unrelated to physical/biological factors
– That general medical conditions are unrelated to behavioural /
psychosocial factors or processes
• Consistent with WHO and ICD guidance to consider indl’s
functional status distinct from diagnostic/symptomatic status
24. Defining a Mental Disorder
• A mental disorder is a syndrome characterised by
clinically significant disturbance in an indl’s
– Cognition
– Emotional regulation
– Behaviour
• that reflects a dysfunction in the psychological,
biological or developmental processes underlying
mental functioning .
• Mental disorders are usually associated with significant
distress or disability in social, occupational or other
important activities
• An expectable or culturally approved response to a
common stressor or loss (e.g. the death of a loved one)
is NOT a mental disorder
25. Summary
• Efficient administrative machinery
• Open process of review
• Emphasis on empirical validation
• Rigorous Field Trial Framework
27. Definition – Critique
• “a careful written examination of a subject that
includes the writer’s opinions”
Macmillan’s Dictionary
• “a report of something such as a political situation
or system, or a person's work or ideas, that
examines it and provides a judgment, especially a
negative one”
Cambridge English Dictionary
29. Failed Deadlines
• Clinician Field trial
– Aug 10 – scheduled to be trained by then
– Dec 11 – training actually completed (14mths late)
– Nov 10 – patients scheduled to be enrolled
– Feb 11 – scheduled to finish trial 1
• “RCP field trials continued until after enrollment
ended in February 2012. Work groups were
provided with results from both field trials and
updated their draft criteria as needed”
32. Distortion of Kappa Values
• According to the authors, of the 23 disorders
– 14 had “very good” or “good” reliability
– 6 had questionable, but 'acceptable' levels
– 03 had “unacceptable” rates
• Only 5 of the 23 DSM 5 diagnoses that achieved kappa
levels of agreement between 0.60–0.79 would have
been considered 'good' in the past
• 9 DSM 5 disorders in the kappa range of 0.40–0.59
previously would have been considered poor
(DSM 5 calls these 'good')
• 3 diagnoses that were below <0.20 (which is barely
better than chance) are found unacceptable
33. Questionable Quality of Field Trials
•Major Depressive Disorder
•Generalized Anxiety Disorder
•GAD - DSM 5 definition was so very poorly done
•DSM 5 had made no changes from the MDD definition
•reliability has been repeatedly studied
•always achieved rates twice as high
•? Incompetence in how the DSM 5 field trials were conducted
•Throws in doubt all of the other results
34. Hypervigilance
• Work group members sign confidentiality agreements to protect
DSM 5 'intellectual property‘
• APA rebuffs calls from 51 mental health associations for an open
and independent scientific review
• APA's legal office tries to stifle criticism and censor internet
derision
– threats of trademark litigation
• Original DSM 5 plan for field trials included no prior public viewing
of criteria sets and no period for public comment
– These are added only under heavy outside pressure
• DSM 5 publishes no aggregations of key areas of concern
identified during public reviews
– Doesn't respond publicly to them
– No indication that public input has had any impact whatever on DSM 5
• APA declares it will “post a complete set of DSM 5 reliability data
in time to allow comments during the final period of public
review”
– NOT DONE
35.
36. CONCLUSIONS
• “Melancholia’s features cluster with greater consistency
than the broad heterogeneity of the disorders and
conditions included in major depression and bipolar
disorder
• The melancholia diagnosis has superior predictive
validity for prognosis and treatment, and it represents a
more homogeneous category for research study.
• We therefore advocate that melancholia be positioned
as a distinct, identifiable and specifically treatable
affective syndrome in the DSM-5 classification”
37. • “I believe you and your colleagues are
fundamentally correct
• But the inclusion of a biological measure would be
very hard to sell to the mood group
• The problem isn’t the test’s reliability, which I think
is better than anything else in psychiatry.
• Rather, it is that the D.S.T. will be the only biological
test for any diagnosis being considered”
Dr William Coryell, Member, APA Assembly’s Committee on DSM5
38. Overdiagnosis
• Binge Eating Disorder
• Disruptive Mood Dysregulation Disorder
• Removal of Bereavement Exclusion
• MDD K=0.32
• Fewer than one-third of antidepressant users have
consulted a mental health professional in the past year
• Four out of five prescriptions for psychotropic drugs are
written by practitioners who are not psychiatrists
(Psychiatric Services, 2009)
• 72% of psychotropic drugs are prescribed without
meeting a psychiatric diagnosis
• (Health Aff (Millwood). 2011 Aug;30(8):1434-42. doi: 10.1377/hlthaff.2010.1024. Proportion of antidepressants
prescribed without a psychiatric diagnosis is growing)
39. • Persons who had a bereavement related depressive syndrome at
baseline were no more likely over a 3-year follow-up period to have a
major depressive episode than those who had no lifetime history of
major depression at baseline.
• Subjects who had had an episode of major depression at baseline
were significantly more likely to have a recurrence of depression
during the 3-year followup than those without a history of depression
or those who had only had bereavement-related depression.
• Mojtabai R. Bereavement-related depressive episodes: characteristics, 3-year course, and implications for the DSM-5. Arch Gen Psychiatry 2011;68:920-8.
• The majority of bereaved and clinically depressed patients are seen
by primary care practitioners
• It is critical that such practitioners be skilled at distinguishing
between clinical depression, which requires treatment, and
uncomplicated grief, which is an entirely normal emotional response
to loss.
40. Why the rush?
• “The need to coordinate DSM-5 with ICD-10-CM coding,
which was scheduled to start Oct 2013”
• Health and Human Services (HHS) Secretary Kathleen G.
Sebelius has announced that the start date for ICD-10-CM
has been postponed. It is not yet clear for how long, but
most likely a year
ICD-10-CM Delay Removes Excuse For Rushing DSM-5 Into Premature Publication,
Psychiatric Times, February 22, 2012
41.
42. Summary
• Poor Diagnostic Consistency
• Empirical Groundwork was incomplete
• Encourages overdiagnosis of mental illness
• Ignored the ONE objective scientific validator
available
• Rushed into implementation when time was
available for a completion of 2nd phase of trials
• Validity of Psychiatry as a science undermined
– Asperger’s removed completely

Notes de l'éditeur
In their introduction to DSM5,
A crossroad had been reached. The need to evolve along with other branches and like other branches was recognised, but
The results of various streams of study revealed consistently that
The last edition for DSM, IV-TR came out in 2000, but even 01 year before it ie.e in 1999 the APA became wary that emerging research was not supporting the boundaries estd for certain mental disorders
This was a remarkable humble and practical document, its courage reflected in statements like
And its practicality in ones like
It even offered a multiaxial system for possible diagnoses
2003-2008
In 2006,
They oversaw they establishment of 13 work groups
Working groups were directed to work in accordance with 4 guiding prinicples
The DSM5 work group conceptualised two kinds of field trials, the first being done in
As they would provide the large sample siezes reqd to test the diagnoses themselves on their rel + CU
The second was a phase of rials at RCPs, testing how these reveions performed when used across the spectrum of MHPs who would eventually be be using it
Input on diagnoses which frequently ended up as causes for litigation were taken from
An executive summitt committee session was held to consolidate all findings from AC chairs, TF chairs and, Forensic advisor, for a preliminary review of each disorder by the assembly and APA board of trustees.
This was followed by a prelminary review by full APA board of trustees
Assembly finally voted in Nov 12 to rec that board approve pblication of DSM5, which the board duly recommended in Dec 12.
Hence the high number of NOS diagnoses
Supported emperically by sharing of genetic & environmental risk factors
And not to validate any specific diagnosis
The scientific indicators or validators suggested to be used for a re-grouping were
These were the proposed criteria to be used to group diagnoses together
This arrangement was done with a view to

This included how

This was a true embodiement of the DSMIV stance that
Finish then DSM5’s journey has come under heavy criticism and at times ridicule,
Phase 1 didn’t actually start till 2010 as criteria were not ready
The routine Clinical Practice (RCP) trials were actually even worse.
Eventually the APA simply gave up on the prospect of ever meeting a deadline and say they would continue
Needless to say there were no Phase 2 trials
In the initally formulated Research Agenda for DSM5, great emphasis was placed on the Kappa statistic, the ability for a diagnostic tool to yield consistent results
Only 1 disorder, for Major neurocognitive disorder reach the conventioanlly accepted Kappa score of 0.7
Had same scores as DSM4 been used 5 of the 23 diagn Only 5 of the 23 DSM 5 diagnoses that achieved kappa levels of agreement between 0.60–0.79 would have been considered 'good' in the past
The DSM5 taskforce reacted by shifting the goalposts. In an AJP editorial in Jan 12, they made a complete Uturn from their earlier stand and began declaring that it would be
What was now happening was a shifting of the goalposts
It wasn’t just the agreeability of the diagnoses themselves, it became clear that the trials themselves were shoddily conducted.

The only other feasable reason that remained was the need to get DSM5 on the market to recover exorbitant consts
This futher puts APA’s and hence Psychiatry’s credibility under a cloud
