Application of the ICD-11 classification of personality disorders.

The ICD-11 Personality Disorder classification was applicable to five clinical cases, which were classified according to Personaity Disorder severity and trait domain qualifiers. We propose that the classification of severity may help inform clinical prognosis and intensity of treatment, whereas the coding of trait qualifiers may help inform the focus and style of treatment. Empirical investigation of such important aspects of clinical utility are warranted.
