[The classification of personality disorders in ICD-11]

The classification of personality disorders in ICD-11 Abstract. In ICD-11, the classification of personality disorders (PD) is no longer categorical but dimensional, along a spectrum defined by the severity of the disorder. The definition of PD is based on the level of impairment of self-directed and interpersonal personality functioning. Only one general diagnostic category "Personality Disorder" remains (ICD-11 Code 6D10). All distinct PD diagnoses from ICD-10 are missing, with the exception of Borderline PD, which can be classified with a "trait qualifier." The type of PD is characterized by specific patterns of five maladaptive personality traits. From the perspective of child and adolescent psychiatry, the most important change from ICD-10 to ICD-11 is the removal of an age limit, meaning PDs can be diagnosed across the lifespan.
