Organization of Clinician-Rated Personality Disorder Types According to Severity of Personality Dysfunction.

The model of personality disorders (PD) allows clinicians to classify personality dysfunction according to four levels of severity. This approach is partially inspired by Kernberg's levels of personality organization, in which various PD types are organized according to their level of severity. This study sought to investigate whether the established PD categories can be organized according to the four levels of PD severity, and to what extent this organization aligns with Kernberg's four levels of personality organization.
