Personality disorders.

Area of Science:

• Psychiatry
• Clinical Psychology
• Mental Health Classification

Background:

• The International Classification of Diseases, 10th Revision (ICD-10) utilized a categorical system for personality disorders.
• Previous classifications faced challenges in capturing the spectrum of personality pathology.
• A need for a more nuanced and clinically applicable system was identified.

Purpose of the Study:

• To provide an overview of the transition in personality disorder classification from ICD-10 to ICD-11.
• To describe the dimensional approach and its core components in ICD-11.
• To discuss the clinical implications and utility of the revised classification.

Main Methods:

• Comparative analysis of classification systems (ICD-10 vs. ICD-11).
• Description of the dimensional model adopted in ICD-11.
• Review of literature and expert consensus regarding the new framework.

Main Results:

• ICD-11 replaces categorical diagnoses with a dimensional approach centered on severity.
• The new system features five broad domains to describe personality pathology.
• This shift aims to improve diagnostic accuracy and clinical relevance.

Conclusions:

• The ICD-11 dimensional classification offers a more flexible and comprehensive framework for personality disorders.
• This approach has the potential to enhance clinical assessment, treatment planning, and research.
• The transition signifies a significant evolution in understanding and diagnosing personality pathology.
