N2 - Objective: The International Classification of Diseases, 11th edition (ICD-11) 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 ICD-10 PD categories can be organized according to the four levels of ICD-11 PD severity, and to what extent this organization aligns with Kernberg’s four levels of personality organization. Method: A sample of 247 patients were rated by their mental health professionals according to ICD-10 PD categories and ICD-11 PD severity levels. Results: The frequencies of ICD-10 PDs on the different ICD-11 PD severity levels were generally found to be consistent with Kernberg’s model. Accordingly, borderline and antisocial PDs predominantly occurred at the most severe levels, whereas anankastic, avoidant, and dependent PDs typically occurred at the milder levels. Only paranoid and histrionic PDs were less consistent with Kernberg’s model. Conclusions: The findings indicate that the new ICD-11 PD severity dimension largely aligns with Kernberg’s model of personality functioning with respect to the organization of PD types. Clinicians may therefore conceptualize familiar PD types in terms of their ICD-11 PD severity and vice versa.
