Background:

The International Classification of Diseases, 11th Revision (ICD-11) introduces novel diagnostic frameworks.
These include a new diagnosis for complex Post-Traumatic Stress Disorder (C-PTSD) and a revised approach to Personality Disorders (PD).

Purpose of the Study:

To delineate the overlap and boundaries between ICD-11's Complex PTSD and Personality Disorder diagnoses.
To provide guiding principles for clinicians differentiating these conditions.

Main Methods:

Review of the ICD-11 diagnostic criteria for Complex PTSD and Personality Disorders.
Analysis of shared features, including impairments in self- and interpersonal functioning and emotional dysregulation.
Identification of key differentiating principles.

Main Results:

Complex PTSD and Personality Disorders share significant features such as emotional dysregulation and impaired functioning.
Distinctions exist that necessitate careful clinical assessment.
Principles concerning trauma, onset, emotion dysregulation, self/interpersonal functioning, and dissociative/psychotic-like states are proposed.

Conclusions:

Understanding the nuances between ICD-11 Complex PTSD and Personality Disorders is crucial for accurate diagnosis.
The proposed principles offer a framework to guide practitioners in distinguishing these related but distinct conditions.
