ICD-11 Personality Disorders Overview

Practical Implications of ICD-11 Personality Disorder Classifications

• Personality disorders (PDs) are linked to lower quality of life, poor health, and higher mortality, creating substantial clinical, familial, and societal burdens.
• The ICD-11 represents a shift from categorical to dimensional diagnosis for PDs, extending application to adolescents.
• Studies support the dimensional utility of the ICD-11 approach in adolescents, highlighting the need for early detection and intervention.
• More research is needed for ICD-11 PD application concerning social relevance, simpler measurement, and longitudinal lifespan studies.
• PDs affect human functioning in areas like affectivity, impulse control, perception, and reaction to stress.
• PDs are highly comorbid with other mental illnesses, affecting treatment and outcomes.
• Life expectancy is shorter for individuals with PDs, especially when comorbid with depression.
• The prevalence of PDs is high in general populations (12.16% in Western countries, 4.1% in Asia), and even higher in psychiatric patients (46-58%).
• Suicide attempts and self-harm are significantly associated with PDs (35% and 22%, respectively, in emergency departments).
• A significant paradigm shift occurred in ICD-11 moving away from traditional categorical descriptions and towards dimensional perspectives.
• This dimensional approach enhances diagnostic continuity and assists in identifying those who can benefit from therapy.
• The ICD-11 focuses on severity by emphasizing impairment in relationships and oneself.
• Five key stylistic traits include Negative Affectivity, Detachment, Disinhibition, Dissociality, and Anankastia.
• The model aligns with psychodynamic frameworks (Kernberg's, object relations) and the five-factor model of personality.
• The ICD-11 distinguishes from DSM-5 by omitting previous categories (except borderline) to emphasize a dimensional model.
• Anankastia contrasted with psychoticism in ICD-11 has better discrimination and cultural validity. The ICD-11 approach offers a more comprehensive portrayal of the personality structure than the DSM-5.
• The ICD-11 differentiates between No Impairment, Personality Difficulty, Mild Personality Disorder, Moderate Personality Disorder, and Severe Personality Disorder.
• Structured clinical interviews are absent for ICD-11; self-report and clinician rating scales evaluate severity.
• The Personality Disorder Severity (PDS-ICD-11) aids in evaluating self and interpersonal dysfunction, also encompassing emotional, cognitive, and behavioral symptoms.
• Self-report instruments, and other measures assess traits related to the dimensional trait model.
• Application of ICD-11 is potentially more suitable for some cultures than the DSM-5, and it is potentially useful in settings including legal evaluations, forensic work, and also bariatric surgery.
• Improved diagnosis and treatment planning for PDs in adolescence are highlighted as potential areas for research.
• The ICD-11 and DSM-5 overlap to varying degrees with different trait domains mapped across systems.

ICD-11-Related Diagnostic Measures

• Currently, there's no structured clinical interview for the ICD-11 model, but self-report and clinician-rating scales exist for assessing severity/functioning.
• The Severity ICD-11 (PDS-ICD-11), measures self/interpersonal dysfunction and related symptoms.
• Existing measures for traits (like the Informant Personality Inventory for ICD-11 or the FFiCD), offer detailed trait information and high correlations with evaluations of personality functioning.
• Other measures (like the PID-5) also serve as relevant comparative assessments.

Treatment and Social Issues

• The ICD-11 promotes patient-centered assessment and treatment tailoring based on severity.
• Utilizing measures for personality functioning and severity enhances clinical decision-making.
• Early intervention during adolescence is associated with improved outcomes for those with potential PDs.
• Psychotherapies can be refined to target specific trait domains like negative affectivity.
• In forensic settings, early identification and treatment are essential due to potential legal implications.
• ICD-11's dimensional approach is deemed more practical than the categorical approach in forensic settings, given its focus on severity.

Future Perspectives and Conclusions

• Existing assessment methods (for ICD-11) for PDs need improvements in diverse clinical applications.
• The implications of the ICD-11 approach are wide-ranging, demanding further research into social, family, and personal relevance of reducing stigma, applying across lifespan developments, and easy applicability.
• Early interventions, and ongoing treatment for various forms (mild to more severe) of PDs in different age groups is desirable and essential.
