ICD-116D11	PROMINENT PERSONALITY TRAITS OR PATTERNS Prominent personality traits or patterns
ICD-10—	No ICD-10 equivalent
DSM-5-TRF60.3	Borderline Personality Disorder (matches only the 6D11.5 borderline pattern qualifier)

1. Definition and nosology

Prominent personality traits or patterns (ICD-11: 6D11 Prominent personality traits or patterns) is not a stand-alone diagnosis but a set of qualifiers: they record which trait domains a personality disorder (6D10) or personality difficulty is expressed through. Severity is coded in 6D10 and the domains here; 6D11 is never assigned on its own.

Personality difficulty is not a mental disorder in ICD-11 — it sits in the chapter “Factors influencing health status” under the code QE50.7. Personality traits cause functional difficulty but fall short of the 6D10 criteria.

2. History

• ICD-11 (2019) — the 10 categorical personality disorders were dropped in favour of a severity rating (6D10) plus five trait domains (6D11.0–6D11.4).
• The borderline pattern (6D11.5) was added separately as the successor to ICD-10 borderline personality disorder (F60.3); in DSM-5-TR the only parallel is the Section III dimensional model.

3. Epidemiology

Precise epidemiological data are limited; subclinical personality traits are widespread in the population.

4. Aetiology and pathogenesis

Same as 6D10 — genetic and environmental interaction.

5. Clinical features

• 6D11.0 Negative affectivity — a broad range of negative emotions: anxiousness, irritability, low self-esteem, emotional lability.
• 6D11.1 Detachment — social and emotional distance: avoidance, restricted affect, refusal of intimacy.
• 6D11.2 Dissociality — disregard for the rights and feelings of others: self-centredness, lack of empathy, exploitativeness.
• 6D11.3 Disinhibition — impulsivity, distractibility, irresponsibility, a pull towards immediate reward.
• 6D11.4 Anankastia — perfectionism, rigid rules, emotional and behavioural control.
• 6D11.5 Borderline pattern — instability of relationships, self-image and affect, impulsivity, fear of abandonment, self-harm and suicidal behaviour.

6. Diagnosis

6.1 Unified diagnostic criteria

A. The diagnosis is made under 6D10 (personality disorder) or QE50.7 (personality difficulty); 6D11 is added only as a qualifier.

B. All domains present to a clinically significant degree are recorded — there may be several.

C. The borderline pattern (6D11.5) may be recorded in addition to any combination of domains.

6.2 Source-specific clarifications

ICD-11 — category somewhat similar to the Z-code for ‘clinical attention to personality problems.’

6.3 Diagnostic algorithm

1. Clinical interview.
2. 5-domain assessment.
3. Exclusion of full PD diagnosis.

6.4 Differential diagnosis

7. Examination and assessment

Personality inventories (PID-5).

8. Treatment

1. Psychotherapy — short-to-medium term; problem-focused CBT or supportive.
2. Stress management and coping skills.
3. Specific intervention for comorbid symptoms.

Treatment methods

1. Brief Psychotherapy — Problem-focused CBT or supportive.
2. DSM-5 — Personality Inventory for DSM-5 (PID-5) — Dimensional personality scale.

9. Prognosis

Improvement with treatment; risk of progression to stable or full PD.

10. Myths and misconceptions

Myth 1: “Personality Difficulty is not a real diagnosis”

Evidence: ICD-11 is the official code; it provides clinical attention to subclinical personality problems.

Myth 2: “Personality difficulty inevitably turns into PD”

Evidence: Some patients experience deterioration, but most stabilize or improve.

Myth 3: “Should only be treated with medication”

Evidence: Psychotherapy is first-line; pharmacotherapy for comorbid symptoms.

Myth 4: “This category is only for labeling ‘anxious’ patients”

Evidence: ICD-11 — clinical response to functional difficulty; provides clinical support.
