psychopathologypersonality disorder

In settings where a brief estimate of personality dysfunction is needed, the Personality Disorder Severity Scale (PDS-ICD-11) provides a structured self-report approach aligned with ICD-11 severity concepts. It is designed to support clinical formulation and monitoring by summarizing the overall level of impairment.

The measure includes 14 items and typically requires about 3 minutes to complete. Items sample broad domains of personality-related functioning, such as self-functioning, interpersonal functioning, and difficulties with emotional and behavioral regulation, yielding a severity-oriented score that can be used to track change over time.

Robert F. Krueger is credited as an author of the Personality Disorder Severity Scale (PDS-ICD-11). Results should be interpreted in context with clinical interview findings and other relevant assessment data rather than used as a standalone diagnostic determination.
