Personality Disorder Test (DSM-5-TR Guide)

The Personality Disorder Test is an educational guide to the 10 DSM-5-TR personality disorders, grouped in three clusters ^[1]. It does not produce a score; it describes the persistent patterns of cognition, emotion and behaviour each cluster covers, and the clinical tools used to assess them, such as the SCID-5-PD, MCMI-IV, PDQ-4+ and PAI.

What does the personality disorder test measure?

This guide does not produce a score. It explains what a personality disorder is and how the DSM-5-TR organizes the 10 specific disorders, so readers and clinicians can see which features each cluster describes.

A personality disorder is a type of mental health condition involving a persistent, pervasive pattern of inner experience and behaviour that:

• deviates markedly from cultural expectations;
• is stable across contexts and time;
• leads to distress or functional impairment;
• is not better explained by another mental health condition or substance use.

DSM-5-TR identifies 10 specific personality disorders organized into three clusters based on descriptive similarities ^[1].

Personality disorders were long viewed as treatment-resistant, but that view has shifted with the development of structured therapies such as Dialectical Behavior Therapy (DBT) for borderline personality disorder, Schema Therapy, Cognitive Analytic Therapy (CAT) and Mentalization-Based Treatment (MBT).

The Alternative Model for Personality Disorders (AMPD) in DSM-5-TR Section III takes a dimensional approach. It combines personality dysfunction (self and interpersonal domains) with maladaptive traits in five domains: negative affectivity, detachment, disinhibition, antagonism and psychoticism ^[2].

The ICD-11 goes further, replacing the categorical personality disorder list with a single severity-based diagnosis plus optional trait domain specifiers.

How do you give the personality disorder test?

Select a cluster in the explorer below to see the disorders and their core features. In clinical practice, personality disorders are assessed with dedicated tools rather than a guide like this one:

• SCID-5-PD (Structured Clinical Interview for DSM-5 Personality Disorders): the criterion standard, a semi-structured clinician-administered interview.
• MCMI-IV (Millon Clinical Multiaxial Inventory): a widely used 175-item self-report scale.
• PDQ-4+ (Personality Diagnostic Questionnaire): a 99-item screening tool with high sensitivity but lower specificity.
• PID-5 (Personality Inventory for DSM-5): measures the Alternative Model trait domains.

DSM-5-TR cluster explorer

Select a cluster to explore the personality disorders and their core features. This is an educational reference, not a diagnostic tool.

Personality disorder diagnosis requires full clinical evaluation by a licensed mental health professional. No self-report tool can diagnose a personality disorder.

How do you score and interpret the personality disorder test?

There is no score and no cutoff. A specific personality disorder can only be diagnosed by a licensed mental health professional after a full clinical evaluation, and only when the general criteria below are met first.

DSM-5-TR general diagnostic criteria

All 10 DSM-5-TR personality disorders must meet these general criteria before a specific disorder is diagnosed.

ICD-11 severity model

The ICD-11 (2019) replaced the categorical DSM-style personality disorder list with a unified severity-based model: Mild, Moderate, or Severe Personality Disorder, with optional trait domain specifiers (Negative Affectivity, Detachment, Dissociality, Disinhibition, Anankastia). This approach better reflects research showing that personality pathology is dimensional, that categorical diagnoses are highly comorbid, and that severity, not category, most strongly predicts outcomes and treatment needs.

Psychometric properties

This guide is educational and has no psychometric properties of its own. Among the tools it describes, the SCID-5-PD interview is the criterion standard; the PDQ-4+ screens with high sensitivity but lower specificity, so a positive screen needs confirmation by interview.

Limitations

• Not a diagnosis. No self-report tool, and no guide, can diagnose a personality disorder.
• Categorical model. The 10-disorder cluster model is highly comorbid: most people diagnosed with one personality disorder meet criteria for one or two more. The DSM-5-TR Alternative Model and ICD-11 take a dimensional approach instead.
• Co-occurring conditions. Depression, anxiety and PTSD commonly co-occur and must be considered in any evaluation.
• Later life. Personality disorders in older adults bring their own features and assessment challenges ^[3].

Personality disorder outcome monitoring

Programmes that treat personality disorders, including DBT and schema therapy, often track co-occurring symptoms with measures such as the PHQ-9, GAD-7 and DERS, alongside personality-specific outcomes.
