When the ICD-11 working group for the revision of the classification of personality disorders was established in 2010, there was both an increasing concern, followed by general consensus, that the existing classification in ICD-10 and DSM-IV were no longer fit for purpose. First, the system was complex, with around 80 criteria and 10 separate categories. These categories had evolved from historical precedents, clinical experience, and committee consensus. There was no coherent model or theory for the diagnoses. Some categories had their origins in Galen’s temperaments described over 1800 years ago (Galen, 192), while others, such as borderline personality disorder, had appeared very recently. Clinicians responded to this confusion by often ignoring the whole concept of personality disorders, resulting in low rates of diagnosis in clinical practice. Rates of clinical diagnoses are generally reported to be less than one-quarter of those in systematic prevalence studies.1 When clinicians did make a personality disorder diagnosis, they usually confined themselves to 2 of the 10 categories; borderline personality disorder or antisocial personality disorder, or used the catch-all ‘personality disorder not otherwise specified’ (PD-NOS), or mixed and other personality disorders (61.0) in ICD-10.
