A case-controlled field study evaluating ICD-11 proposals for relational problems and intimate partner violence

Area of Science:

• Mental Health
• Clinical Psychology
• Public Health

Background:

• Intimate partner relationship problems and maltreatment significantly impact physical and mental health.
• Current classification guidelines (ICD-10) are vague, leading to inconsistent application.
• Proposed ICD-11 guidelines are more operationalized for improved clarity.

Purpose of the Study:

• To evaluate the impact of proposed ICD-11 guidelines on classification accuracy for relational problems and maltreatment.
• To compare the diagnostic accuracy of ICD-10 versus ICD-11 guidelines using standardized clinical vignettes.
• To assess the influence of clinician factors on classification performance.

Main Methods:

• An international panel of 738 mental health professionals from 65 nations participated.
• Clinicians applied either ICD-10 or proposed ICD-11 guidelines to experimentally manipulated case vignettes.
• Vignettes included varying combinations of individual mental health diagnoses and relational problems/maltreatment.

Main Results:

• ICD-11 guidelines demonstrated significantly better classification accuracy than ICD-10, particularly when co-morbid mental health problems were present.
• Clinician demographics (gender, language, region) did not substantially affect classification performance.
• Despite improved operationalization, issues with guideline adherence were observed.

Conclusions:

• The proposed ICD-11 guidelines offer enhanced accuracy for classifying relational problems and maltreatment.
• Training is essential to address pre-existing archetypes that may override ICD-11 guidelines.
• Addressing training needs is crucial before the official ICD-11 release to ensure reliable clinical application.
