The classification of personality

disorders in ICD-11: Implications

for forensic psychiatry






PETER   TYRER,   Centre for Mental Health, Department of Medicine, Imperial
   College, London W6  8RP, UK


Twenty  years ago, Criminal Behaviour and Mental Health carried an article from me
entitled 'Flamboyant, erratic, dramatic, borderline, antisocial, sadistic, narcissistic,
histrionic and impulsive personality disorder: who cares which?' (Tyrer, 1992).
The many  years since have confirmed the answer I gave in the article, the only ones
who  care are those with a vested interest in keeping these terms. The average
clinician certainly does not seem to take much interest in these curious adjectives.
When   the  International Classification of Diseases (11th edition) (ICD-11)
working group  for the revision of personality disorders met to review the use
of the diagnostic categories in the ICD-10 (World Health Organisation, 1992)
classification of personality disorders across different countries, we found that
borderline, dissocial and mixed personality disorders were responsible for 95% of
all personality disorder diagnoses, but more botheringly, they were diagnosed in
well under 5%   of all patients. When epidemiological studies show that the
prevalence of personality disorders in the community is at or above 5% (Coid
et al., 2006; Huang et al., 2009), there is clearly something wrong - this diagnostic
system apparently leads to the 'Great Clinician Switch Off'.
   Why  is this? The classification clearly has no clinical utility, and possible reasons
include (1) the stigmatic nature of the label, (2) the high comorbidity between
different personality disorders, which is clearly a false separation as nobody is
prepared to argue that this represents true comorbidity in the form of separate
disorders (Livesley and Jackson, 1986) and (3) the very high proportion of
what is called personality disorder not otherwise specified in the Diagnostic and
Statistical Manual (DSM) classification (Verheul and Widiger, 2004), giving the
clear message 'a plague on your classification, it does not represent what I see in
my clinic'. The more damning criticism is that neither the current US DSM nor
