Assessment of the ICD-11 dimensional trait model: An introduction to the special section.

Abstract

The 11th edition of the World Health Organization's International Classification of Diseases (ICD-11; World Health Organization, 2018) is scheduled to include a major shift in the classification of personality disorders. All (but one) of the ICD-10 categorical personality disorder syndromes will be deleted from the ICD-11, replaced by a five-domain dimensional trait model. The five ICD-11 trait domains are negative affectivity, detachment, dissociality, disinhibition, and anankastia. Clinicians first rate a patient with respect to a level of personality disorder severity, followed by the option of also rating the person with respect to the five trait domains along with a borderline pattern qualifier. This special section of Psychological Assessment is concerned with the self-report assessment of the ICD-11 personality disorders section, particularly (albeit not exclusively) with respect to the dimensional trait model.
